• How a planetarium show discovered a spiral at the edge of our solar system

    If you’ve ever flown through outer space, at least while watching a documentary or a science fiction film, you’ve seen how artists turn astronomical findings into stunning visuals. But in the process of visualizing data for their latest planetarium show, a production team at New York’s American Museum of Natural History made a surprising discovery of their own: a trillion-and-a-half mile long spiral of material drifting along the edge of our solar system.

    “So this is a really fun thing that happened,” says Jackie Faherty, the museum’s senior scientist.

    Last winter, Faherty and her colleagues were beneath the dome of the museum’s Hayden Planetarium, fine-tuning a scene that featured the Oort cloud, the big, thick bubble surrounding our Sun and planets that’s filled with ice and rock and other remnants from the solar system’s infancy. The Oort cloud begins far beyond Neptune, around one and a half light years from the Sun. It has never been directly observed; its existence is inferred from the behavior of long-period comets entering the inner solar system. The cloud is so expansive that the Voyager spacecraft, our most distant probes, would need another 250 years just to reach its inner boundary; to reach the other side, they would need about 30,000 years. 

    The 30-minute show, Encounters in the Milky Way, narrated by Pedro Pascal, guides audiences on a trip through the galaxy across billions of years. For a section about our nascent solar system, the writing team decided “there’s going to be a fly-by” of the Oort cloud, Faherty says. “But what does our Oort cloud look like?” 

    To find out, the museum consulted astronomers and turned to David Nesvorný, a scientist at the Southwest Research Institute in San Antonio. He provided his model of the millions of particles believed to make up the Oort cloud, based on extensive observational data.

    “Everybody said, go talk to Nesvorný. He’s got the best model,” says Faherty. And “everybody told us, ‘There’s structure in the model,’ so we were kind of set up to look for stuff,” she says. 

    The museum’s technical team began using Nesvorný’s model to simulate how the cloud evolved over time. Later, as the team projected versions of the fly-by scene into the dome, with the camera looking back at the Oort cloud, they saw a familiar shape, one that appears in galaxies, Saturn’s rings, and disks around young stars.

    “We’re flying away from the Oort cloud and out pops this spiral, a spiral shape to the outside of our solar system,” Faherty marveled. “A huge structure, millions and millions of particles.”

    She emailed Nesvorný to ask for “more particles,” with a render of the scene attached. “We noticed the spiral of course,” she wrote. “And then he writes me back: ‘what are you talking about, a spiral?’” 

    While fine-tuning a simulation of the Oort cloud, a vast expanse of ice material leftover from the birth of our Sun, the ‘Encounters in the Milky Way’ production team noticed a very clear shape: a structure made of billions of comets and shaped like a spiral-armed galaxy, seen here in a scene from the final Space ShowMore simulations ensued, this time on Pleiades, a powerful NASA supercomputer. In high-performance computer simulations spanning 4.6 billion years, starting from the Solar System’s earliest days, the researchers visualized how the initial icy and rocky ingredients of the Oort cloud began circling the Sun, in the elliptical orbits that are thought to give the cloud its rough disc shape. The simulations also incorporated the physics of the Sun’s gravitational pull, the influences from our Milky Way galaxy, and the movements of the comets themselves. 

    In each simulation, the spiral persisted.

    “No one has ever seen the Oort structure like that before,” says Faherty. Nesvorný “has a great quote about this: ‘The math was all there. We just needed the visuals.’” 

    An illustration of the Kuiper Belt and Oort Cloud in relation to our solar system.As the Oort cloud grew with the early solar system, Nesvorný and his colleagues hypothesize that the galactic tide, or the gravitational force from the Milky Way, disrupted the orbits of some comets. Although the Sun pulls these objects inward, the galaxy’s gravity appears to have twisted part of the Oort cloud outward, forming a spiral tilted roughly 30 degrees from the plane of the solar system.

    “As the galactic tide acts to decouple bodies from the scattered disk it creates a spiral structure in physical space that is roughly 15,000 astronomical units in length,” or around 1.4 trillion miles from one end to the other, the researchers write in a paper that was published in March in the Astrophysical Journal. “The spiral is long-lived and persists in the inner Oort Cloud to the present time.”

    “The physics makes sense,” says Faherty. “Scientists, we’re amazing at what we do, but it doesn’t mean we can see everything right away.”

    It helped that the team behind the space show was primed to look for something, says Carter Emmart, the museum’s director of astrovisualization and director of Encounters. Astronomers had described Nesvorný’s model as having “a structure,” which intrigued the team’s artists. “We were also looking for structure so that it wouldn’t just be sort of like a big blob,” he says. “Other models were also revealing this—but they just hadn’t been visualized.”

    The museum’s attempts to simulate nature date back to its first habitat dioramas in the early 1900s, which brought visitors to places that hadn’t yet been captured by color photos, TV, or the web. The planetarium, a night sky simulator for generations of would-be scientists and astronauts, got its start after financier Charles Hayden bought the museum its first Zeiss projector. The planetarium now boasts one of the world’s few Zeiss Mark IX systems.

    Still, these days the star projector is rarely used, Emmart says, now that fulldome laser projectors can turn the old static starfield into 3D video running at 60 frames per second. The Hayden boasts six custom-built Christie projectors, part of what the museum’s former president called “the most advanced planetarium ever attempted.”

     In about 1.3 million years, the star system Gliese 710 is set to pass directly through our Oort Cloud, an event visualized in a dramatic scene in ‘Encounters in the Milky Way.’ During its flyby, our systems will swap icy comets, flinging some out on new paths.Emmart recalls how in 1998, when he and other museum leaders were imagining the future of space shows at the Hayden—now with the help of digital projectors and computer graphics—there were questions over how much space they could try to show.

    “We’re talking about these astronomical data sets we could plot to make the galaxy and the stars,” he says. “Of course, we knew that we would have this star projector, but we really wanted to emphasize astrophysics with this dome video system. I was drawing pictures of this just to get our heads around it and noting the tip of the solar system to the Milky Way is about 60 degrees. And I said, what are we gonna do when we get outside the Milky Way?’

    “ThenNeil Degrasse Tyson “goes, ‘whoa, whoa, whoa, Carter, we have enough to do. And just plotting the Milky Way, that’s hard enough.’ And I said, ‘well, when we exit the Milky Way and we don’t see any other galaxies, that’s sort of like astronomy in 1920—we thought maybe the entire universe is just a Milky Way.'”

    “And that kind of led to a chaotic discussion about, well, what other data sets are there for this?” Emmart adds.

    The museum worked with astronomer Brent Tully, who had mapped 3500 galaxies beyond the Milky Way, in collaboration with the National Center for Super Computing Applications. “That was it,” he says, “and that seemed fantastical.”

    By the time the first planetarium show opened at the museum’s new Rose Center for Earth and Space in 2000, Tully had broadened his survey “to an amazing” 30,000 galaxies. The Sloan Digital Sky Survey followed—it’s now at data release 18—with six million galaxies.

    To build the map of the universe that underlies Encounters, the team also relied on data from the European Space Agency’s space observatory, Gaia. Launched in 2013 and powered down in March of this year, Gaia brought an unprecedented precision to our astronomical map, plotting the distance between 1.7 billion stars. To visualize and render the simulated data, Jon Parker, the museum’s lead technical director, relied on Houdini, a 3D animation tool by Toronto-based SideFX.

    The goal is immersion, “whether it’s in front of the buffalo downstairs, and seeing what those herds were like before we decimated them, to coming in this room and being teleported to space, with an accurate foundation in the science,” Emmart says. “But the art is important, because the art is the way to the soul.” 

    The museum, he adds, is “a testament to wonder. And I think wonder is a gateway to inspiration, and inspiration is a gateway to motivation.”

    Three-D visuals aren’t just powerful tools for communicating science, but increasingly crucial for science itself. Software like OpenSpace, an open source simulation tool developed by the museum, along with the growing availability of high-performance computing, are making it easier to build highly detailed visuals of ever larger and more complex collections of data.

    “Anytime we look, literally, from a different angle at catalogs of astronomical positions, simulations, or exploring the phase space of a complex data set, there is great potential to discover something new,” says Brian R. Kent, an astronomer and director of science communications at National Radio Astronomy Observatory. “There is also a wealth of astronomics tatical data in archives that can be reanalyzed in new ways, leading to new discoveries.”

    As the instruments grow in size and sophistication, so does the data, and the challenge of understanding it. Like all scientists, astronomers are facing a deluge of data, ranging from gamma rays and X-rays to ultraviolet, optical, infrared, and radio bands.

    Our Oort cloud, a shell of icy bodies that surrounds the solar system and extends one-and-a-half light years in every direction, is shown in this scene from ‘Encounters in the Milky Way’ along with the Oort clouds of neighboring stars. The more massive the star, the larger its Oort cloud“New facilities like the Next Generation Very Large Array here at NRAO or the Vera Rubin Observatory and LSST survey project will generate large volumes of data, so astronomers have to get creative with how to analyze it,” says Kent. 

    More data—and new instruments—will also be needed to prove the spiral itself is actually there: there’s still no known way to even observe the Oort cloud. 

    Instead, the paper notes, the structure will have to be measured from “detection of a large number of objects” in the radius of the inner Oort cloud or from “thermal emission from small particles in the Oort spiral.” 

    The Vera C. Rubin Observatory, a powerful, U.S.-funded telescope that recently began operation in Chile, could possibly observe individual icy bodies within the cloud. But researchers expect the telescope will likely discover only dozens of these objects, maybe hundreds, not enough to meaningfully visualize any shapes in the Oort cloud. 

    For us, here and now, the 1.4 trillion mile-long spiral will remain confined to the inside of a dark dome across the street from Central Park.

  • Astronomers Discover Most Powerful Cosmic Explosions Since the Big Bang

    Astronomers have seen the most energetic cosmic explosions yet, a new class of eruptions termed "extreme nuclear transients".

    At any given time across the universe, massive cosmic bodies are releasing incomprehensible amounts of energy. Stars burn like celestial nuclear fusion reactors, quasars emit thousands of times the luminosity of the Milky Way galaxy, and asteroids slam into planets. But all of these pale in comparison to a new class of events discovered by researchers at the University of Hawai’i’s Institute for Astronomy. According to their findings published June 4 in the journal Science Advances, it’s time to classify the universe’s most energetic explosions as extreme nuclear transients–or ENTs.
    ENTs are as devastating as they are rare. They only occur when a massive star at least three times heavier than the sun drifts too close to a supermassive black hole. The colliding forces subsequently obliterate the star, sending out plumes of energy across huge swaths of space. Similar events known as tidal disruption eventsare known to occur on asmaller scale, and have been documented for over a decade. But ENTs are something else entirely.
    “ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain luminous for years, far surpassing the energy output of even the brightest known supernova explosions.”
    Hinkle was first tipped off to ENTs while looking into transients—longlasting flares that spew energy from a galaxy’s center. Two particularly strange examples captured by the European Space Agency’s Gaia mission caught his eye. The pair of events brightened over a much longer timeframe than previously documented transients, but lacked some of their usual characteristics.
    “Gaia doesn’t tell you what a transient is, just that something changed in brightness,” Hinkle said. “But when I saw these smooth, long-lived flares from the centers of distant galaxies, I knew we were looking at something unusual.”
    Hinkle soon reached out to observatory teams around the world for what would become a multiyear project to understand these anomalies. In the process, a third suspect was detected by the Zwicky Transient Facility at the Palomar Observatory in San Diego. After months of analysis, Hinkle and collaborators realized they were witnessing something unprecedented.

    The ENTs analyzed by astronomers displayed smoother, longer lasting flares that pointed towards something very particular—a supermassive black hole accreting a giant, wayward star.
    This contrasts with a more standard black hole that typically acquires its material and energy unpredictably, resulting in irregular brightness fluctuations.
    The energy and luminosity of an ENT boggles the mind. The most powerful ENT documented in Hinkle’s study, Gaia18cdj, generated 25 times more energy than the most powerful known supernovae. For reference, a standard supernova puts out as much energy in a single year as the sun does across its entire 10 billion year lifespan. Gaia18cdj, meanwhile, manages to give off 100 suns’ worth of energy over just 12 months.
    The implications of ENTs and their massive energy surges go far beyond their impressive energy outputs. Astronomers believe they contribute to some of the most pivotal events in the cosmos.
    “These ENTs don’t just mark the dramatic end of a massive star’s life. They illuminate the processes responsible for growing the largest black holes in the universe,” said Hinkle.
    From here on Earth, ENTs can also help researchers as they continue studying massive, distant black holes.
    “Because they’re so bright, we can see them across vast cosmic distances—and in astronomy, looking far away means looking back in time,” explained study co-author and astronomer Benjamin Shappee. “By observing these prolonged flares, we gain insights into black hole growth when the universe was half its current age… forming stars and feeding their supermassive black holes 10 times more vigorously than they do today.”
    There’s a catch for astronomers, however. While supernovae are relatively well-documented, ENTs are estimated to occur at least 10 million times less often. This means that further study requires consistent monitoring of the cosmos backed by the support of international governments, astronomical associations, and the public.

  • Scientists Spot Mysterious Object in Our Galaxy Pulsing Every 44 Minutes

    Astronomers have spotted something strange and spectacular: a mysterious object that keeps emitting pulses every 44 minutes.In a press release from Australia's Curtin University, which was part of the international team that detected the object just 15,000 light-years away in our Milky Way galaxy, astronomers explained that the find was all the more stunning because the signal is coming in the form of both X-rays and radio waves.The object, which was named ASKAP J1832-0911 after Australia's ASKAP radio telescope that was used to detect it, was discovered emitting two-minute-long pulses that would pause and then repeat 44 minutes later. As the Curtin press release explains, the researchers lucked out when they realized that NASA’s Chandra X-ray Observatory was observing the same part of the sky and detected the same repeating signal in X-ray form.This dual-natured pulse belongs to a newly-discovered class of space phenomena known as "long-period radio transients," or LPTs for short.Discovered in 2022 by the International Centre for Radio Astronomy Research — which also sponsored this latest study — these mystery pulses have unknown origins and occur in fixed intervals of minutes or hours. They're considered by astronomers to be remarkably slow as compared to the signals emitted by pulsars, those rapidly-rotating stars that send out similar bursts every few milliseconds when their poles point in Earth's direction.In the years since they were first discovered, astronomers around the world have only detected some 10 other LPTs — but before now, none have been run through X-ray telescopes as well.According to Ziteng "Andy" Wang, an ICRAR-affiliated Curtin astronomer and the lead author a paper about the finding that was just published in the journal Nature, discovering the dual nature of LPTs in such a coincidental manner "felt like finding a needle in a haystack.""The ASKAP radio telescope has a wide field view of the night sky, while Chandra observes only a fraction of it," Wang explained in the Curtin press release. "So, it was fortunate that Chandra observed the same area of the night sky at the same time."Because LPTs are such a new phenomenon to astronomers, they can't say for sure what causes them.When the first of them were discovered, astronomers posited that they could be coming from magnetars, a type of neutron star with extremely strong magnetic fields that also emit radio pulses at faster intervals, leading to the ICRAR team positing that they may have an "ultra-long-period magnetar" on their hands.While the magnetar theory appears to have been scrapped, the astronomers behind this update in LPT knowledge are hopeful that it will help them figure out what these strange, slow pulses are about."This object is unlike anything we have seen before," said Wang.Share This Article

  • Playdate Season 2 review: Fulcrum Defender, Dig! Dig! Dino! and Blippo+

    Playdate Season Two is here, bringing with it two new games for the quirky yellow handheld every week until July 3. And if the first two titles are any indication of what this season will be like, it's sure to be a great one. Season Two kicked off on May 29 with the arcade action game Fulcrum Defender — from the studio behind FTL: Faster Than Light and Into the Breach — and the delightfully chill Dig! Dig! Dino!. The two games couldn't be more different from each other, but they're both bangers in their own right.
    Panic also released Blippo+, which can only be described as a fever dream of cable TV, with the first drop of Season Two, and it is amazingly bizarre.
    Fulcrum Defender
    Subset Games
    "Survive for 10min!" sounded almost like a threat when I first started reading through Fulcrum Defender's How To Play guide. Between all the on-screen information you need to pay attention to, the many different types of enemies that'll be attacking and the various weapon upgrades you can earn over the course of a run, there's a lot to take in, and I braced myself for a tense and complicated playing experience. But, while that may be closer to the case on Hard Mode, I found that Fulcrum Defender wasn't all that punishing of a shooter on Normal Mode. It's a challenge, for sure, but one with a surprisingly achievable goal that I was able to enjoy without losing my mind. At least, not until crossing the 10-minute mark. After that, all hell breaks loose.
    In Fulcrum Defender, you're positioned at the center of a circular arena and have to fend off a continuous swarm of enemies. Your shield will take damage any time an enemy collides with it, and once enough have breached that zone, it's game over. To avoid that, you need to shoot them down one by one, using the crank to aim your weapon and the D-pad to shoot. Some enemies can be taken out in one shot, but others — distinguished by their filled-in appearance — require multiple shots. Over time, you'll earn weapon upgrades to build out a more powerful defense system, with options like large, guided projectiles and a flail that can knock out several enemies in one sweep.
    It's unexpectedly addicting. The music is beautiful and calming, giving the whole thing a pleasant atmosphere despite the fact that you're surrounded by enemies at any given moment and trying not to die. Once I realized it was absolutely possible to survive 10 minutes and even go beyond that, I got sucked into the loop of trying over and over to beat my high scores. I'd love to see a global leaderboard for this game at some point, because I just know I'd be floored by how long some players will be able to last.
    If you liked this one and want to know a little more about the making of it, be sure to check out our interview with Jay Ma, the co-founder of Fulcrum Defender developer Subset Games.
    Dig! Dig! Dino!
    Dom2D & Fáyer
    I can't think of anything I'd rather be doing right now than pretending to be a paleontologist and casually digging for bones. No thoughts, just dig. That's exactly what Dig! Dig! Dino! has going on, and it's awesome.
    You're working as part of a crewat the site of some really unusual dinosaur fossils, and it's your job to dig up new bones and artifacts. Once you've got the entire skeleton of a particular dinosaur, you can scan it in the lab to reveal what it was like when it was alive. That information, coupled with the peculiar artifacts scattered around the site, paints a picture of some pretty strange activities that went on there long ago. For example, some of these dinosaurs seem to have had crystals growing out of their bodies, and it looks like they were warned about the asteroid extinction event. Fishy!
    The gameplay is extremely low stakes — this is one for when you just want to zone out playing something that'll keep your hands busy. You're equipped with a shovel, a drill and a radar gadget for detecting items beneath the surface, and have no time-sensitive goals to hit. You only have so much energy, though, which will be consumed with each use of your tools. When you run out, the round is over. But you can visit each site as many times as you need to in order to find all of the dinosaur pieces hidden there, so it can be a really casual undertaking if you want it to be.
    It's a really nice time, with a fun story to tie it all together. You'll get a solid few hours of playtime out of this, too, and the simplicity of it all means you can put it down and come back to it later without having to rack your memory to figure out where you left off. I loved this one.
    Blippo+
    Panic
    What can one even say about Blippo+? This bizarre "1-bit television" experience came as a bonus with the first Season Two games, and it is something. Panic first teased it back in December 2024 as a Steam title, but here it is for the Playdate now, complete with a roster of channels playing hallucinatory programs and Femtofax, an interactive message board of sorts where you can find affirmations, neighborhood drama, chatter among amateur astronomers and more. Panic describes it as being "comparable to an old episode of The Twilight Zone," but it's more like an old episode of The Twilight Zone if it were made by Tim & Eric and aired after midnight on Adult Swim. I think I am obsessed with it?
    I'm really interested to see where this goes. I would totally park my Playdate in a dockon my desk and leave Blippo+ running in the background all day if it has enough fresh material to sustain it. The song playing alongside the endlessly scrolling Blippo+ TV guide screen is already stuck in my head, and I don't hate it.

    Playdate Season 2 review: Fulcrum Defender, Dig! Dig! Dino! and Blippo+
    Playdate Season Two is here, bringing with it two new games for the quirky yellow handheld every week until July 3. And if the first two titles are any indication of what this season will be like, it's sure to be a great one. Season Two kicked off on May 29 with the arcade action game Fulcrum Defender — from the studio behind FTL: Faster Than Light and Into the Breach — and the delightfully chill Dig! Dig! Dino!. The two games couldn't be more different from each other, but they're both bangers in their own right. Panic also released Blippo+, which can only be described as a fever dream of cable TV, with the first drop of Season Two, and it is amazingly bizarre. Fulcrum Defender Subset Games "Survive for 10min!" sounded almost like a threat when I first started reading through Fulcrum Defender's How To Play guide. Between all the on-screen information you need to pay attention to, the many different types of enemies that'll be attacking and the various weapon upgrades you can earn over the course of a run, there's a lot to take in, and I braced myself for a tense and complicated playing experience. But, while that may be closer to the case on Hard Mode, I found that Fulcrum Defender wasn't all that punishing of a shooter on Normal Mode. It's a challenge, for sure, but one with a surprisingly achievable goal that I was able to enjoy without losing my mind. At least, not until crossing the 10-minute mark. After that, all hell breaks loose. In Fulcrum Defender, you're positioned at the center of a circular arena and have to fend off a continuous swarm of enemies. Your shield will take damage any time an enemy collides with it, and once enough have breached that zone, it's game over. To avoid that, you need to shoot them down one by one, using the crank to aim your weapon and the D-pad to shoot. Some enemies can be taken out in one shot, but others — distinguished by their filled-in appearance — require multiple shots. Over time, you'll earn weapon upgrades to build out a more powerful defense system, with options like large, guided projectiles and a flail that can knock out several enemies in one sweep. It's unexpectedly addicting. The music is beautiful and calming, giving the whole thing a pleasant atmosphere despite the fact that you're surrounded by enemies at any given moment and trying not to die. Once I realized it was absolutely possible to survive 10 minutes and even go beyond that, I got sucked into the loop of trying over and over to beat my high scores. I'd love to see a global leaderboard for this game at some point, because I just know I'd be floored by how long some players will be able to last. If you liked this one and want to know a little more about the making of it, be sure to check out our interview with Jay Ma, the co-founder of Fulcrum Defender developer Subset Games. Dig! Dig! Dino! Dom2D & Fáyer I can't think of anything I'd rather be doing right now than pretending to be a paleontologist and casually digging for bones. No thoughts, just dig. That's exactly what Dig! Dig! Dino! has going on, and it's awesome. You're working as part of a crewat the site of some really unusual dinosaur fossils, and it's your job to dig up new bones and artifacts. Once you've got the entire skeleton of a particular dinosaur, you can scan it in the lab to reveal what it was like when it was alive. That information, coupled with the peculiar artifacts scattered around the site, paints a picture of some pretty strange activities that went on there long ago. For example, some of these dinosaurs seem to have had crystals growing out of their bodies, and it looks like they were warned about the asteroid extinction event. Fishy! The gameplay is extremely low stakes — this is one for when you just want to zone out playing something that'll keep your hands busy. You're equipped with a shovel, a drill and a radar gadget for detecting items beneath the surface, and have no time-sensitive goals to hit. You only have so much energy, though, which will be consumed with each use of your tools. When you run out, the round is over. But you can visit each site as many times as you need to in order to find all of the dinosaur pieces hidden there, so it can be a really casual undertaking if you want it to be. It's a really nice time, with a fun story to tie it all together. You'll get a solid few hours of playtime out of this, too, and the simplicity of it all means you can put it down and come back to it later without having to rack your memory to figure out where you left off. I loved this one. Blippo+ Panic What can one even say about Blippo+? This bizarre "1-bit television" experience came as a bonus with the first Season Two games, and it is something.

  • Webb Telescope Uncovers Hidden Active Galactic Nuclei

    Highlights

    Webb reveals dusty black holes that may link quasars and LRDs
    Hidden AGNs found by JWST could explain black hole growth
    Scientists find objects that may bridge the gap between LRDs and quasars

    Advertisement

    An obscured population of huge and massive black holes has been revealed by the James Webb Space Telescope. This discovery could bridge the gap between quasars and the Little Red Dots. These are active galactic nuclei galaxies, overlapped or blurred by active blackholes, occupied by dust. Their bright nature makes them detectable in spite of the dust surrounding them. However, during December 2022, astronomers found a new type of AGN that they called Little Red Dots, because they appear as tiny, fat red spots.Connection of AGN with Quasars is Still a MysteryFor more than a decade, the study has been led by Dale Kocevski, an astronomer at Colby College. Their team includes scientists like Jorryt Matthee, an astrophysicist at the Institute of Science and Technology, who contributed to the understanding of little dots and their connection with quasars. Their connection is still a mystery that prompts them to find the objects with properties in between.The Old Universe Abundantly Occupied by Hidden QuasarsIn a new study Yoshiki Matsuoka, associate professor at the Research Center for Space, told Live Science, the scientists are surprised to find that the not-so-clear quasars had occupied a large portion of the early universe. Out of 13 galaxies, 9 were found to have clear signs of active supermassive blackholes in connection with the heavy dust that hides them.Findings Can Give Insights into the Study of Universe EvolutionJorryt Matthee, the head of the old research, said that although there are abundant new objects found in the universe, the gap between the two known populations found by JWST is too high, and thus, there is a possibility that these belong to that missing population lying in between the known ones, providing fresh insights into how these giants formed and evolved in the early universe. The findings were reported on May 7, 2025, in the preprint database arXiv.Future Study Scopes to Unveil the Nature of LRDThe team is planning to observe 30 more objects from the sample of the Subaru Telescope. This can reveal that the behaviour of the hidden quasars aligns with Little Red Dots. Furthermore, the gases that surround them can reveal the mysterious nature of LRD.

  • New Imaging Technique Makes the Sun Look Like a Swirling Pink Liquid

    A swirling sea of pink, where fluffy tufts float majestically upward, while elsewhere violet plumes rain down from above. This is the Sun as seen in groundbreaking new images — and they're unlike anything you've ever laid eyes on.As detailed in a new study published in the journal Nature Astronomy, scientists have leveraged new coronal adaptive optics tech to bypass the blurriness caused by the turbulence of the Earth's atmosphere, a time-old obstacle that's frustrated astronomers' attempts to see features on our home star at a resolution better than 620 miles. Now, they've gotten it down to just under 40 miles — a light year sized leap.The result is some of the clearest images to date of the fine structures that make up the Sun's formidable corona, the outermost layer of its atmosphere known for its unbelievable temperatures and violent, unpredictable outbursts.The authors are optimistic that their blur-bypassing techniques will be a game-changer."These are by far the most detailed observations of this kind, showing features not previously observed, and it's not quite clear what they are," coauthor Vasyl Yurchyshyn, a research professor at the New Jersey Institute of Technology's Center for Terrestrial Research, said in a statement about the work."It is super exciting to build an instrument that shows us the Sun like never before," echoed lead author Dirk Schmidt, an adaptive optics scientist at the US National Solar Observatory.Stretching for millions of miles into space, the corona is the staging ground for the Sun's violent outbursts, which range from solar storms, to solar flares, to coronal mass ejections. One reason scientists are interested in these phenomena is because they continue to batter our own planet's atmosphere, playing a significant role in the Earth's climate and wreaking havoc on our electronics. Then, at a reach totally beyond our very limited human purview, is the corona's mighty solar wind, which sweeps across the entire solar system, shielding it from cosmic rays.But astronomers are still trying to understand how these solar phenomena occur. One abiding mystery is why the corona can reach temperatures in the millions of degrees Fahrenheit, when the Sun's surface it sits thousands of miles above is no more than a relatively cool 10,000 degrees. The conundrum even has a name: the coronal heating problem.The level of detailed captured in the latest images, taken with an adaptive optics system installed on the Goode Solar Telescope at the CSTR, could be transformative in probing these mysteries.One type of feature the unprecedented resolution revealed were solar prominences, which are large, flashy structures that protrude from the sun's surface, found in twisty shapes like arches or loops. A spectacular video shows a solar prominence swirling like a tortured water spout as it's whipped around by the sun's magnetic field.Most awe-inspiring of all are the examples of what's known as coronal rain. Appearing like waterfalls suspended in midair, the phenomenon is caused as plasma cools and condenses into huge globs before crashing down to the sun's surface. These were imaged at a scale smaller than 100 kilometers, or about 62 miles. In solar terms, that's pinpoint accuracy."With coronal adaptive optics now in operation, this marks the beginning of a new era in solar physics, promising many more discoveries in the years and decades to come," said coauthor  Philip R. Goode at the CSTR in a statement.More on our solar system: Scientists Detect Mysterious Object in Deep Solar SystemShare This Article
