#AceNewsDesk – NASA has released two spectacular new images of the Tarantula Nebula taken by the James Webb Telescope, shedding light on a nearby region of the universe that could give astronomers new insight into how stars are formed.

The Tarantula Nebula, officially known as 30 Doradus, is in the Large Magellanic Cloud galaxy, a stone’s throw away from Earth at a mere 161,000 light-years and part of the Local Group of galaxies closest to the Milky Way.

Previous images taken of the nebula have shown it with long clouds of dust and gas appearing to emanate from its centre like a web, resulting in its spidery nickname.

But the new images, produced using the James Webb Telescope’s infrared sensors, provide a more complex and detailed picture of what is happening at the nebula’s centre, where stars are born at a furious pace.

The first image, taken with the telescope’s Near-Infrared Camera (NIRCam), covers an area 340 light years across, and shows a cluster of massive stars making space for themselves at the nebula’s centre by eroding the surrounding matter with what NASA labelled “blistering radiation”.

Smaller points of light visible in the gas and dust clouds are “protostars”, young stars that are still gaining mass as they emerge from the nebula’s “web” and take their place at its centre.

The protostars have never been photographed before, as the surrounding matter is too dense for visible light to travel through.

A second image released by NASA, taken with the telescope’s Mid-Infrared Instrument (MIRI), gives the region a whole new look, with the cooler gas and dust glowing blue but the hot stars fading into the background.The area surrounding the Tarantula Nebula’s central star cluster as taken by the James Webb Telescope’s Mid-Infrared Instrument (MIRI).(Supplied: NASA, ESA, CSA, STScI, Webb ERO Production Team)none

The Tarantula Nebula is of particular interest to astronomers because its chemical composition and behaviour is similar to what would have occurred in regions of the early universe when star formation was at its peak — what is known as the universe’s “cosmic noon”.

The new pictures are the latest in a series of spectacular images produced by the James Webb Telescope, a joint venture led by NASA along with the European and Canadian space agencies.

The six-tonne telescope, the successor to the 32-year-old Hubble Space Telescope, was launched into orbit in December last year, arriving at a point of equilibrium between the Sun and the Earth in January and producing its first image for public release in July.

Allowing astronomers to see through the massive clouds of dust and gas that visible-light observatories like Hubble are unable to is one of the four main goals of the James Webb project.

The other three goals are to witness the first stars and galaxies forming near the beginning of the early universe, to further our understanding of how galaxies assemble over billions of years, and to tell us more about the atmospheres of planets beyond our solar system, perhaps even furthering the search for extraterrestrial life.

NASA JAMES WEBB TELESCOPE REPORT: Takes Its First-Ever Direct Image of Distant World Outside Our Solar System

#AceNewsDesk – For the first time, astronomers have used NASA’s James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable.

The star HIP 65425 & 4 views of its planet “b.” The background of the image is black with many white & blue stars; it is not from Webb and is labeled the “Digitized Sky Survey.” Star HIP 65425 is labeled at top center. It has 4 diffraction spikes (telescope artifacts) from the top, bottom, left, & right. Diagonal lines down from the star to the bottom of the image highlight 4 inset boxes. From left to right, first is Webb’s NIRCam view of the exoplanet. It's a purple dot with purple bars at 11 & 5 o’clock. The bars are telescope artifacts, not physically present. The planet & artifacts have been colored purple. The filter used, F300M (3 micrometers), is on the image. Next is a similar NIRCam view using filter F444W (4.44 micrometers). This view is colored blue & has the artifact bars. Next is a MIRI view, colored orange. No bars are present. The filter is F1140C (11.40 micrometers). Finally, a MIRI view using filter F1550C (15.50 micrometers). It is a red large dot. A white star icon on all 4 images represents the parent star.
Editor’s Note: This post highlights images from Webb science in progress, which has not yet been through the peer-review process.

The image, as seen through four different light filters, shows how Webb’s powerful infrared gaze can easily capture worlds beyond our solar system, pointing the way to future observations that will reveal more information than ever before about exoplanets.This image shows the exoplanet HIP 65426 b in different bands of infrared light, as seen from the James Webb Space Telescope: purple shows the NIRCam instrument’s view at 3.00 micrometers, blue shows the NIRCam instrument’s view at 4.44 micrometers, yellow shows the MIRI instrument’s view at 11.4 micrometers, and red shows the MIRI instrument’s view at 15.5 micrometers. These images look different because of the ways the different Webb instruments capture light. A set of masks within each instrument, called a coronagraph, blocks out the host star’s light so that the planet can be seen. The small white star in each image marks the location of the host star HIP 65426, which has been subtracted using the coronagraphs and image processing. The bar shapes in the NIRCam images are artifacts of the telescope’s optics, not objects in the scene. (Unlabeled version.) Credit: NASA/ESA/CSA, A Carter (UCSC), the ERS 1386 team, and A. Pagan (STScI).

“This is a transformative moment, not only for Webb but also for astronomy generally,” said Sasha Hinkley, associate professor of physics and astronomy at the University of Exeter in the United Kingdom, who led these observations with a large international collaboration. Webb is an international mission led by NASA in collaboration with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

The exoplanet in Webb’s image, called HIP 65426 b, is about six to 12 times the mass of Jupiter, and these observations could help narrow that down even further. It is young as planets go — about 15 to 20 million years old, compared to our 4.5-billion-year-old Earth.

Astronomers discovered the planet in 2017 using the SPHERE instrument on the European Southern Observatory’s Very Large Telescope in Chile and took images of it using short infrared wavelengths of light. Webb’s view, at longer infrared wavelengths, reveals new details that ground-based telescopes would not be able to detect because of the intrinsic infrared glow of Earth’s atmosphere.

Researchers have been analyzing the data from these observations and are preparing a paper they will submit to journals for peer review. But Webb’s first capture of an exoplanet already hints at future possibilities for studying distant worlds.

Since HIP 65426 b is about 100 times farther from its host star than Earth is from the Sun, it is sufficiently distant from the star that Webb can easily separate the planet from the star in the image.

Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) are both equipped with coronagraphs, which are sets of tiny masks that block out starlight, enabling Webb to take direct images of certain exoplanets like this one. NASA’s Nancy Grace Roman Space Telescope, slated to launch later this decade, will demonstrate an even more advanced coronagraph.

“It was really impressive how well the Webb coronagraphs worked to suppress the light of the host star,” Hinkley said.

Taking direct images of exoplanets is challenging because stars are so much brighter than planets. The HIP 65426 b planet is more than 10,000 times fainter than its host star in the near-infrared, and a few thousand times fainter in the mid-infrared.

In each filter image, the planet appears as a slightly differently shaped blob of light. That is because of the particulars of Webb’s optical system and how it translates light through the different optics.

“Obtaining this image felt like digging for space treasure,” said Aarynn Carter, a postdoctoral researcher at the University of California, Santa Cruz, who led the analysis of the images. “At first all I could see was light from the star, but with careful image processing I was able to remove that light and uncover the planet.”

While this is not the first direct image of an exoplanet taken from space – the Hubble Space Telescope has captured direct exoplanet images previously – HIP 65426 b points the way forward for Webb’s exoplanet exploration.

“I think what’s most exciting is that we’ve only just begun,” Carter said. “There are many more images of exoplanets to come that will shape our overall understanding of their physics, chemistry, and formation. We may even discover previously unknown planets, too.”

FEATURED: OneWeb takes $229m hit from satellites not returned by Russia

#AceNewsDesk – Launch postponements also a part of the writeoff as company pins hopes on SpaceX according to the Register by Mon.05: Sep 2022 // 14:03 UTC

OneWeb has taken a $229.2 million hit after it cancelled launches from Russia’s Baikonur facility, and a number of its low Earth orbit satellites that were waiting to be sent to space were not returned.

The detail was disclosed in OneWeb’s annual report [PDF], in which the company announced revenue for the financial year to 31 March 2022 of $9.6 million, but a net loss of $389.8 million. The company is partly owned by the UK government since it joined forces with Indian outfit Bharti Global to rescue OneWeb from bankruptcy in 2020.

This incident is a consequence of the Russian invasion of Ukraine, which caused OneWeb to suspend all launches from the Baikonur facility in Kazakhstan, operated by the Russian space agency Roscosmos. The space agency had already demanded the British government give up its stake in OneWeb and sought guarantees that its satellites would not be put to any military use.

OneWeb soon afterwards inked a deal with Elon Musk’s SpaceX to use its rockets to continue putting OneWeb’s satellites into orbit, a move that surprised many as the company is a rival for SpaceX’s own Starlink satellite network.

However, the cancellation of the Baikonur launches set back OneWeb’s plans. As The Register reported earlier this year, the company was until then closing in on the completion of its constellation of satellites, having put 428 of them into orbit which represented 66 percent of the total.

According to OneWeb, this cancellation of the launches from Baikonur has left 36 of its satellites in Russian hands, resulting in the impairment of a portion of OneWeb’s prepaid launch insurance. The operating loss for the year excluding the effect of the impairment was $196.7 million.

OneWeb CEO Neil Masterson states in the company’s annual report that the six remaining launches required for complete global coverage with its first generation of satellites (GEN 1) were postponed, and it is now working with SpaceX towards global network coverage in 2023. The company announced in June that contracts for all six additional launches had been secured.

In July, OneWeb and French satellite operator Eutelsat signed a memorandum of understanding to merge the two companies into a larger global player in space-based telecoms.

The combined entity would have satellite networks in both low Earth orbit and geostationary orbit, enabling it to offer the benefits of both. The merger is expected to complete in the first half of 2023. It is believed that OneWeb will continue to operate the low Earth orbit part of the business and remain headquartered in the UK.

OneWeb said it has received $2.7 billion in equity funding and has no external debt other than lease liabilities. ®

BREAKING: Three meteor showers set to grace our skies this weekend — this is where to see them

#AceBreakingNews – Looking for something spectacular to brighten a cold, dark winter’s night? ……………Well, this weekend might just have something in store: not one, not two, but three meteor showers active at the same time — combining to provide a celestial firework display almost all through the night.

Although the best night to watch will be the evening and night of Saturday, July 30, through to dawn on Sunday morning, the three showers will be near their peak rates from tonight. So you’ll have plenty of chances to catch the show while avoiding bad weather or other commitments.

Best of all, there’s going to be a new moon, which means there won’t be much glare spoiling the show.

What are meteor showers?

The solar system is full of debris left behind from the formation of the planets more than 4.5 billion years ago. Some of this debris — comets and asteroids — moves on orbits that cross Earth’s path around the sun.

Each time those comets and asteroids swing in towards the sun, they shed debris. Over hundreds or thousands of years their orbits become shrouded in broad streams of dust.

Earth continually passes through these streams of detritus as it moves around the sun, which gives birth to the annual meteor showers. Each year, we return to the same place in our orbit, encounter the same stream of debris, and get another nice show as that debris burns up harmlessly, 80 kilometres overhead.

In the depths of the Australian winter, Earth is moving through a bit of space where three streams of debris intersect with our planet’s orbit. Those three streams give birth to the stars of this weekend’s show: the Southern Delta Aquariids, the Alpha Capricornids, and the Piscis Austrinids.

The International Meteor Organisation has 3D animated visualisations of the Southern Delta Aquariid and the Alpha Capricornid meteor streams, which show how the debris is distributed across space.

A tale of three showers

So, let’s introduce the stars of the show.

The Southern Delta Aquariids is the most active of the three showers, with the fastest-moving meteors. Most of the meteors you’ll see this weekend will likely be members of this stream.

The origin of the Southern Delta Aquariids is the topic of some debate. They are one of several meteor showers seemingly linked to one parent object, as though a large comet fell apart long ago, leaving behind a vast amount of debris, potentially including fragments large enough to be comets in their own right.

Over millennia, the debris has spread out, so Earth runs into it multiple times each year. At the moment, the Southern Delta Aquariids are tentatively tied to a comet called 96P/Machholtz, which is the most active object in the debris stream.

The Southern Delta Aquariids have been known to throw up some surprises. In 2006, they produced an outburst, with some people observing more than 60 meteors per hour at their peak. No outburst is forecast for this year, but you never know what might happen!

The second of our triumvirate of showers is the Alpha Capricornids. These produce the slowest meteors of the three showers. They also have a reputation for being a “fireball” shower — often producing spectacular meteors that outshine the brightest stars.

These are the meteors you’re most likely to catch on film, and provide a great opportunity to practice astrophotography.

The final shower, the Piscis Austrinids, are perhaps the least studied of the three. Like the Alpha Capricornids, they are a minor shower that yields just a few meteors per hour, even at their peak. Their meteors are of medium speed.

So where, and when, should I look?

The key for observers is to work out when the shower’s “radiant” will be above the horizon. The radiant is the point in the sky from which all the meteors in the shower appear to radiate.

Meteor showers are named after the location of their radiant. The Alpha Capricornids, for example, radiate from a point near the star Alpha Capricorni.

The radiants for the meteor showers will be high in the eastern sky, around 11pm local time. The planets Jupiter and Saturn, as well as the bright stars Fomalhaut, Altair (to the north-east) and Achernar (to the south-east) will be visible, weather permitting.(Supplied:  Museums Victoria/Stellarium)none

In the case of our midwinter trio, we’re quite lucky. All three radiants rise in the early-to-mid evening from Australia, and reach a reasonable altitude by about 10pm.

As a result, you’ll be able to see meteors any time from the mid-evening onward. The best rates will be visible from about 10pm, until dawn.

Once you’re settled into a comfortable spot from which to observe, try to avoid looking at your phone. You’ll want to let your eyes properly adjust to the darkness so you can see the faintest meteors. Glancing at a screen, even for a second, will send you back to square one.

A map showing the relative positions of the showers
By morning, around 5am, local time, on Sunday, July 31, the meteor showers will appear to radiate from the western sky. The planets Saturn, Jupiter, and Mars should be visible too. (Supplied: Museums Victoria/Stellarium)none

We find the best place to look when watching a meteor shower is around 45 degrees above the horizon, and about 45 degrees to the left or the right of the radiant.

In the early evening, it would therefore be best to look to the east or northeast. By midnight, and immediately after, looking to the north would be best. And in the hours before dawn, you should look west or northwest.

And don’t fret once it’s over! While these three showers are shaping up to put on a decent show, they aren’t the best meteoric event of the year. That’s the Geminids, coming up in December. So there’s much to look forward to yet!

FEATURED: Loads of Precursors For RNA Have Been Detected in The Center of Our Galaxy

This is our daily post that is shared across Twitter & Telegram and published first on here with Kindness & Love XX on peace-truth.com/

#AceNewsDesk – The heart of the Milky Way is a hotspot for molecules that combine to form RNA: A new survey of the thick, molecular clouds that shroud the galactic center has revealed the presence of a wide range of nitriles – organic molecules that are often toxic in isolation, but also constitute the building blocks of molecules essential for life.

The increase in prebiotic molecules (molecules involved in the emergence of life) identified in the galactic center, particularly those associated with RNA, has implications for our understanding of how life emerges in the Universe – and how it did so here on Earth.

“Here we show that the chemistry that takes place in the interstellar medium is able to efficiently form multiple nitriles, which are key molecular precursors of the ‘RNA World‘ scenario,” explained astrobiologist Víctor Rivilla of the Spanish National Research Council and the National Institute of Aerospace Technology in Spain.

Precisely how life emerged on Earth is a mystery whose bottom scientists are extremely keen to reach. That information will yield important clues to discovering exoplanets likely to harbor living organisms.

One version is that RNA emerged first from the metaphorical ooze, self-replicating and diversifying all on its own; this is what’s called the RNA World Hypothesis.

We’re not likely to ever get direct evidence from Earth, but we can put together more and more clues to figure out how plausible and likely this scenario is. One of the questions raised by this hypothesis is about the source of RNA prebiotic molecules such as nitriles. Were they here on Earth from the start, or could they have been carried in from space on meteorites and asteroids?

We know the inner Solar System, including Earth, was subject to a period of intense asteroid bombardment very early in its history. We’ve also found prebiotic molecules on meteorscomets, and asteroids hanging around the Solar System today. And where do meteors, comets and asteroids get them?

Well, probably the clouds they were born in: cold molecular clouds that give birth to stars. Once a star finishes forming from a section of cloud, the cloud leftovers go on to form everything else in a planetary system – planets, comets, asteroids, dwarf planets, and whatever else might be lurking about.

The Solar System’s birth cloud is long gone, but the center of the galaxy is thick with molecular clouds. It’s called the Central Molecular Zone, and scientists have found a bunch of prebiotic molecules hanging around there.

One particular cloud, named G+0.693-0.027, is especially interesting. There’s no evidence of star formation there yet, but scientists believe that a star or stars will form there in the future.

“The chemical content of G+0.693-0.027 is similar to those of other star-forming regions in our galaxy, and also to that of Solar System objects like comets,” Rivilla said.

“This means that its study can give us important insights about the chemical ingredients that were available in the nebula that give rise to our planetary system.”

The researchers used two telescopes to study the spectrum of light coming from the cloud. When certain elements or molecules absorb and re-emit light, this can be seen on the spectrum as a darker or lighter line. Interpreting these absorption and emission lines can be tricky, but it can also be used to identify which molecules are present: each one has its own spectral signature.

By carefully studying and analyzing emission features from G+0.693-0.027, Rivilla and his colleagues identified a range of nitriles, including cyanic acid, cyanoallene, propargyl cyanide, and cyanopropyne. They also made tentative detections of cyanoformaldehyde, and glycolonitrile.

Previous observations of G+0.693-0.027 revealed the presence of cyanoformaldehyde, and glycolonitrile. This suggests that nitriles are among the most abundant chemical families in the Milky Way, and that the most basic building blocks for RNA can be found in the clouds that give birth to stars and planets.

But there is – of course, as there always is – more work to be done.

“We have detected so far several simple precursors of ribonucleotides, the building blocks of RNA,” explained astrobiologist Izaskun Jiménez-Serra, also of the Spanish National Research Council and the National Institute of Aerospace Technology.

“But there are still key missing molecules that are hard to detect. For example, we know that the origin of life on Earth probably also required other molecules such as lipids, responsible for the formation of the first cells. Therefore we should also focus on understanding how lipids could be formed from simpler precursors available in the interstellar medium.”

The research has been published in Frontiers in Astronomy and Space Sciences.

WASHINGTON: New Library of Congress Podcast Explores “Space on the Page”

This is our daily post that is shared across Twitter & Telegram and published first on here with Kindness & Love ❤️❤️ on My.Daz.blog

#AceNewsRoom With ‘Kindness & Wisdom’ Mar.20, 2022 @acenewsservices

Follow Our Breaking & Daily News Here As It Happens:

The John W. Kluge Center at the Library of Congress is pleased to announce the release of “Space on the Page,” a new podcast that explores the universe not with a rocket but through ideas.

In six episodes, hosts David Baron and Lucas Mix will interview authors and scientists who think and write about space exploration and the search for life beyond Earth. Baron and Mix are holders of the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology, Exploration and Scientific Innovation, as well as researchers and authors on the connection between science and humanity.

In the first three episodes, available today, the subject is Mars and our society’s fascination with the red planet — past, present and future.

The first episode describes the Mars “craze” that struck Earth at the start of the 20th century, leading humans to run wild with speculation that the red planet might harbor an advanced civilization. Historian of astronomy and affiliate of the Lowell Observatory William Sheehan explains the science that spawned this imaginative idea, and the optical illusion that caused some astronomers to believe Mars was covered with irrigation canals.

In the second episode, Georgetown University biologist Sarah Stewart Johnson joins Baron to explain how new discoveries about Mars, missions like NASA’s Perseverance Rover, and a better understanding of life on Earth have propelled the quest to find microbial life on Mars, and Johnson ponders what the answers might say about life elsewhere in the universe.

In the third episode, science journalist David Whitehouse discusses the dream of sending human missions to Mars, looking at the concrete steps forward being taken by NASA, other space agencies and private entrepreneurs, as well as the many constraints and risks — biological, technological, and social — that must be overcome before we see the first footprint in red Martian soil.

In the next three episodes, which will be released on April 13, Mix brings science fiction writers Nnedi Okorafor, Becky Chambers and John Scalzi into conversation with scientists Betül Kaçar of the University of Wisconsin, Rika Anderson of Carleton College and Frank Rosenzweig of Georgia Tech. Together they examine how the human imagination depicts everything that we anticipate, hope and fear about what is currently unknown.

Baron and Mix are recent holders of the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology, Exploration and Scientific Innovation at the John W. Kluge Center at the Library of Congress. Chair holders are charged with a mission to investigate the interface between human society and the scientific exploration of the cosmos and to bring the fruits of that investigation to the public.

The Kluge Center’s mission, as established in 2000, is to reinvigorate the interconnection between thought and action, bridging the gap between scholarship and policymaking. To that end, the center brings some of the world’s great thinkers to the Library to make use of the Library collections and engage in conversations addressing the challenges facing democracies in the 21st century.

The Library of Congress is the world’s largest library, offering access to the creative record of the United States — and extensive materials from around the world — both on-site and online. It is the main research arm of the U.S. Congress and the home of the U.S. Copyright Office. Explore collections, reference services and other programs and plan a visit at loc.gov; access the official site for U.S. federal legislative information at congress.gov; and register creative works of authorship at copyright.gov.The NASA/Library of Congress Chair in Astrobiology, Exploration, and Scientific Innovation represents an opportunity for high-level scholarship to understand the interface between human society and the scientific exploration of the cosmos. In the spirit of Barry Blumberg, whose life and work spanned multiple disciplines, the Blumberg Program is interested in the concept of exploration broadly defined to include any aspect of space exploration within the parameters of NASA’s mission to “reveal the unknown for the benefit of humankind.”

WORLDWIDE: SpaceX loses 40 satellites to geomagnetic storm a day after launch

#AceNewsReport – Feb.10: Such solar “storms” are caused by powerful explosions on the sun’s surface, which spit out plasma and magnetic fields that can hit the Earth.

#AceDailyNews says SpaceX has lost dozens of satellites after they were hit by a geomagnetic storm a day after launch, causing them to fall from orbit and burn up according to BBC News Report:

Onlookers watch a SpaceX Falcon 9 rocket launch from Cape Canaveral, carrying 49 Starlink satellites
This Falcon 9 rocket launch on 3 February carried 49 Starlink satellites, most of which were caught by the storm

The company, owned by billionaire Elon Musk, said up to 40 of 49 satellites from last week’s launch were hit.

They had been due to join its Starlink satellite internet project.

Starlink is Mr Musk’s bid to provide high-speed internet using thousands of orbiting satellites. 

The system is relatively expensive, but can be used in places where wired connections cannot. For example, in Tonga, where January’s earthquake severed the island’s nation’s undersea data cable, a Starlink station is being built in nearby Fiji to help restore access.

The latest 49 satellites were deployed about 210km (130 miles) above the Earth’s surface. SpaceX said “each satellite achieved controlled flight” after being sent up on 3 February.

However, a day later, the geomagnetic storm hit the Earth. It is the same kind of mechanism that creates aurorae like the Northern Lights, but it can have dangerous effects too.

This storm warmed up the atmosphere and made it much more dense than expected:

“Onboard GPS suggests the escalation speed and severity of the storm caused atmospheric drag to increase up to 50% higher than during previous launches,” SpaceX said.

SpaceX tried to put the satellites into a “safe mode”, turning them to fly edge-on to minimise drag.

The drag was strong enough to stop the satellites ever getting out of that “safe mode” and back into the orbit they needed to reach to be stable. Instead, “up to 40” will fall back into the Earth’s atmosphere and burn up.

Jacob Geer, the UK Space Agency’s Head of Space Surveillance, said he does not expect “any part” of the satellites to hit the ground.

“Events like this are a reminder that space is challenging – getting satellites or astronauts into orbit is still not easy,” he said.

WORLDWIDE: IAU REPORT: Astronomers have launched an initiative to curb the impact of artificial satellites on important astronomical research, arguing for tighter regulations on projects like Elon Musk’s Starlink network #AceNewsDesk report

#AceNewsReport – Feb.06: The center describes its main mission as being to “mitigate the negative impact of satellite constellations on ground-based optical and radio astronomy observations as well as humanity’s enjoyment of the night sky.”

#AceDailyNews says according to RT News Report: The International Astronomical Union (IAU) announced the creation of the Centre for the Protection of the Dark and Quiet Sky on Thursday, with president Debra Elmegreen saying it would help ensure that technological advances “do not inadvertently impede our study and enjoyment of the sky.”

The body will engage with policymakers around the world in an attempt to tighten regulations on man-made satellites and space infrastructure. It will also push companies like Elon Musk’s Starlink and Amazon’s Project Kuiper to minimize light pollution created with their satellites.

Satellite networks delivering broadband internet are of the biggest concern for the scientists, as thousands of objects orbit the Earth at a relatively low altitude of only a few hundred kilometers. Their quick movement during dusk and dawn leaves bright lines that can be traced by telescopes and interfere with the readings. The satellite transmissions can also meddle with radio telescopes and astronomy antennas.

The work will be led by the US National Optical-Infrared Astronomy Research Laboratory (NOIRLab) in Tucson, Arizona, which is a center for optical astronomy, and the Square Kilometre Array Organisation (SKAO), which is headquartered in Manchester, UK and is delivering the world’s most powerful networks of radio telescopes.

NASA: Intends to keep operating the International Space Station until the end of 2030, after which the ISS would be crashed into a remote part of the Pacific Ocean known as Point Nemo, according to newly published plans outlining its future #AceNewsDesk report

#AceNewsReport – Feb.05: Launched in 2000, the space lab has orbited 227 nautical miles above Earth with more than 200 astronauts from 19 different countries enjoying stints aboard — representing a continuous human presence in space.

#AceDailyNews says according to a CNN NASA plans to retire the International Space Station by 2031 by crashing it into the Pacific Ocean: We look forward to sharing our lessons learned and operations experience with the private sector to help them develop safe, reliable, and cost-effective destinations in space,” said Phil McAlister, director of commercial space at NASA Headquarters in a statement.

The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a fly around of the orbiting lab that took place following its undocking from the Harmony module's space-facing port on Nov. 8, 2021.

NASA said that commercially operated space platforms would replace the ISS as a venue for collaboration and scientific research. “The private sector is technically and financially capable of developing and operating commercial low-Earth orbit destinations, with NASA’s assistance.

“The report we have delivered to Congress describes, in detail, our comprehensive plan for ensuring a smooth transition to commercial destinations after retirement of the International Space Station in 2030.”

Space graveyard

In the International Space Station Transition Report, NASA said the plan was for the ISS to fall to Earth in an area known as the South Pacific Oceanic Uninhabited Area — also known as Point Nemo. The report said that its budget estimate assumed that the deorbit would happen in January 2031. 

Named after the submarine sailor in Jules Verne’s novel “Twenty Thousand Leagues Under the Sea,” Point Nemo is the point in the ocean that is farthest from land and has been a watery grave for many other spacecraft. The area is approximately 3,000 miles off of New Zealand’s eastern coast and 2,000 miles north of Antarctica and it’s estimated that space-faring nations such as the US, Russia, Japan and European countries have sunk more than 263 pieces of space debris there since 1971.

The report said the ISS would perform thrusting maneuvers that would ensure “safe atmospheric entry.”

Third decade

The ISS won’t rest on its laurels for the next eight years. NASA said goals for the next decade including using the ISS as “analog for a Mars transit mission,” according to the report. 

“The International Space Station is entering its third and most productive decade as a groundbreaking scientific platform in microgravity,” said Robyn Gatens, director of the International Space Station at NASA Headquarters, said in the statement. 

“This third decade is one of results, building on our successful global partnership to verify exploration and human research technologies to support deep space exploration, continue to return medical and environmental benefits to humanity, and lay the groundwork for a commercial future in low-Earth orbit.” 

Tensions with Russia worry former US astronauts about the partnership in space

“We look forward to maximizing these returns from the space station through 2030 while planning for transition to commercial space destinations that will follow.”

The space station has been home to many scientific firsts.

The first item to be 3D-printed on the space station occurred in 2014. NASA astronaut Kate Rubins sequenced DNA in space for the first time in 2016.

And the fifth state of matter, called a Bose-Einstein condensate, was produced in space by NASA’s Cold Atom Lab on the station in 2018.Astronauts have learned how to grow lettuces and leafy greens in space.

The first space-grown salad was sampled by astronauts in 2015. Now, they’re even growing radishes and chilis on the station.

This could be used to one day help astronauts grow their own food on deep space missions.

China, whose astronauts have long been excluded from the ISS, launched the first module of its planned space station last year.

While not as large as the ISS, the Chinese space station is expected to be fully operational by the end of this year. Russia has said it will leave the ISS project in 2025 and plans to build its own space station that could launch in 2030.

(SWEDEN) Lund University Report: The Atmosphere of This Extreme Exoplanet Has an Intriguing Similarity to Earth #AceNewsDesk report

#AceNewsReport – Feb.03: Astronomers have just peered into the atmosphere of one of the most extreme exoplanets ever discovered.

#AceNewsDesk says in the past, astronomers often assumed that the atmospheres of exoplanets exist as a uniform layer and try to understand it as such,” says astronomer Jens Hoeijmakers of Lund University in Sweden: The research has been published in Nature Astronomy.

Although it’s absolutely not habitable (at least as we understand it), the exoplanet WASP-189b is the first in which scientists have been able to probe distinct atmospheric layers, each with their own chemical compositions and characteristics.

“But our results demonstrate that even the atmospheres of intensely irradiated giant gas planets have complex three-dimensional structures.”

WASP-189b is a member of one of the most intriguing subsets of exoplanets: hot Jupiters. These extreme worlds are gas giants – like Jupiter – but on insanely close orbits with their host stars, whizzing around in less than 10 days. Naturally, their temperatures are therefore scorching.

In addition, we don’t know why they are like that. According to our current models of planetary formation, a gas giant can’t form that close to its star, because the gravity, radiation, and intense stellar winds ought to keep the gas from clumping together; yet, of the nearly 5,000 exoplanets confirmed to date, over 300 could be hot Jupiters. Learning more about these hell-worlds should thus reveal more about the dynamics of planetary systems.

WASP-189b, about 322 light-years away, is among the most extreme (although it’s not quite the most). It’s about 1.6 times the size of Jupiter, and orbits its star on a breakneck 2.7-day period. That star is young and hot, which means surface temperatures of WASP-189b reach up to 3,200 degrees Celsius (5,792 degrees Fahrenheit) on its day side, making the planet hotter than some stars.

It’s also one of the brightest transiting exoplanets known; that is, it passes between us and its star. In turn, that makes it very attractive for atmospheric studies.

“We measured the light coming from the planet’s host star and passing through the planet’s atmosphere,” explains astronomer Bibiana Prinothof Lund University, who led the research.

“The gases in its atmosphere absorb some of the starlight, similar to ozone absorbing some of the sunlight in Earth’s atmosphere, and thereby leave their characteristic ‘fingerprint’. With the help of HARPS [High Accuracy Radial Velocity Planet Searcher aboard ESO’s La Silla Observatory] we were able to identify the corresponding substances.”

As is often seen in hot Jupiters, those gases included vapors of heavy metals. WASP-189b’s atmosphere is drifting with clouds of gaseous iron, titanium, chromium, magnesium, vanadium and manganese.

Interestingly, the researchers also found traces of titanium oxide, which has never been conclusively detected in an exoplanetary atmosphere before, the researchers said. Titanium oxide is found rarely in nature on Earth, but on WASP-189b, its presence could be helping shape the atmosphere.

“Titanium oxide absorbs short-wave radiation, such as ultraviolet radiation,” says astrophysicist Kevin Heng of the University of Bern.

“Its detection could therefore indicate a layer in the atmosphere of WASP-189b that interacts with the stellar irradiation similarly to how the ozone layer does on Earth.”

There was another big clue that the team was observing layers in the exoplanet’s atmosphere, too. Elements in space are detected spectrally; that is, we split the light detected by our instruments into the full spectrum, and look for brighter or darker lines. These indicate that something is either amplifying or absorbing those wavelengths, what we call emission or absorption lines.

Absorption lines can then be traced to specific elements that we know absorb those wavelengths. But the absorption lines from WASP-189b were not quite where the researchers expected them to be.

“We believe that strong winds and other processes could generate these alterations,” Prinoth said.

“And because the fingerprints of different gases were altered in different ways, we think that this indicates that they exist in different layers – similarly to how the fingerprints of water vapor and ozone on Earth would appear differently altered from a distance, because they mostly occur in different atmospheric layers.”

Obviously we won’t be traveling to WASP-189b anytime soon. Even if we were, life as we know it would be mega-kaput before we even landed; however, the research still has relevance to the search for life. It represents a new milestone in probing exoplanetary atmospheres, which is where we are most likely to spot the signs of alien life.

“I am often asked if I think my research is relevant to the search for life elsewhere in the Universe. My answer is always yes. This type of study is a first step in this search,” Prinoth said.
