Behold, the Solar System in All its X-ray Glory

Using the eROSITA space telescope, MPE researchers have successfully isolated the X-ray glow from our Solar System, revealing its impact on the soft X-ray sky. The findings, published in Science, underscore the importance of considering Solar System processes when analyzing X-ray data and highlight eROSITA’s role in advancing not only astrophysics but also heliophysics. from Universe Today https://ift.tt/CqpQzc4 via IFTTT

Exoplanets Without Lots of Water Can't Maintain Their Carbon Cycles

Water is critical to life because cells need liquid to function. That's why scientists focus on finding and studying exoplanets in habitable zones. But even if they're in habitable zones, exoplanets need lots of water to support their carbon cycles. So without water, exoplanets become inhospitable greenhouse planets, regardless if they're in habitable zones or not. from Universe Today https://ift.tt/qjrp2OF via IFTTT

NASA’s SPHEREx Telescope Just Mapped the Cosmic Ices That Will Someday Build Planets

New missions mean new capabilities - and one particularly interesting new mission is finally up and running. Data is starting to come in from SPHEREx, the medium-class surveyor that is mapping the entire sky every six months. A paper based on some of that early data was recently published in The Astrophysical Journal, mapping ice and compounds called Polycyclic Aromatic Hydrocarbons (PAHs) throughout some interesting regions of our Milky Way. from Universe Today https://ift.tt/tSA04co via IFTTT

What Happens When Light Goes Boom? Part 4: What Brad Bradington Is Good For

Cherenkov radiation isn't just a beautiful phenomenon. It turns up in nuclear reactors, in the upper atmosphere, in gamma ray telescopes on three continents, in a cubic kilometer of Antarctic ice, and in hospital imaging suites.

What Happens When Light Goes Boom? Part 3: Brad Bradington Sprints

We have the crowd. We have the star. Now it's time to put them together. Here's exactly what happens — and why — when a charged particle outruns the local speed of light in a material. Also: why it's always blue. from Universe Today https://ift.tt/Sa1f5qF via IFTTT

How a Black Hole and a Shredded Star Could Light Up a Galaxy

In 2014, a strange cloudy object called G2 made a close approach to Sagittarius A*, (Sag A*) the supermassive black hole at the heart of the Milky Way Galaxy. Astronomers were pretty excited, partly because they thought it might get torn apart by Sag A*'s intense gravitational pull. That didn't happen, and the event was a cosmic fizzle. Instead, G2 skipped around the black hole. Various observations showed that it wasn't just a gas cloud. It was likely a dusty protostellar object encased in a dusty cloud. Or perhaps several merged stars. But, it survived the flyby and continued on a shortened orbit. from Universe Today https://ift.tt/0hRZeAO via IFTTT

Small Trojan Asteroids Defy Expectations

Understanding the beginning of the solar system requires us to look at some very strange places. One such place is at the so-called “Trojan” asteroids that share Jupiter’s orbit in front of and behind it. But for a long time, these cosmic time capsules have held a mystery for astronomers: why are they color-coded? The populations of larger asteroids are very clear split into two distinct groups - the “reds” and the “less reds”, because apparently they’re all red to some extent. A new paper from researchers in Japan tried to solve this mystery by taking a close look at even smaller asteroids, and their findings, published in a recent edition of The Astronomical Journal, actually brings up a completely different question - why don’t smaller Trojan asteroids have the same color-coding? from Universe Today https://ift.tt/PYa7Dy3 via IFTTT

To Survive Deep Space, Astronauts May Owe a Debt to Microscopic Worms

Living long-term on the Moon means surviving the devastating toll that deep space takes on a human body. Astronauts in low gravity environments suffer muscle and bone loss, vision-altering fluid shifts, and heavy radiation exposure - all of which are incredibly hazardous to our biology. So, to help future lunar explorers survive, a new crew just arrived at the International Space Station (ISS). That might not sound surprising, except this crew is composed of worms. from Universe Today https://ift.tt/tbXZFIB via IFTTT

Watch This Dark Volcanic Ash Creep Across the Red Planet

Mars is well known as a static, frozen desert. We tend to think of the only thing changing on the surface of the Red Planet is due to the occasional dust storm. But if you look closely - and are willing to wait decades - you’ll see the planet is very much alive - at least in the environmental sense. The European Space Agency just released some spectacular new images from the High Resolution Stereo Camera (HRSC) on its Mars Express Orbiter, one of which shows a surprisingly “fast” geological change happening in Utopia Planitia. A dark, ominous-looking blanket of volcanic ash is actively creeping across the bright red sands - and it's moving (relatively) fast. from Universe Today https://ift.tt/CXuoepl via IFTTT

What Happens When Light Goes Boom? Part 2: The Crowd, the Molasses, and the Speed of Light (Sort Of)

Before Brad Bradington can sprint down the red carpet, we need to understand the crowd. Specifically, we need to understand why a crowd of atoms and molecules slows down light — and why that creates a loophole that changes everything. from Universe Today https://ift.tt/Lgs62ZG via IFTTT

Early Galaxies Were Surrounded by Huge Clouds of Hydrogen, and Astronomers Found a Whole Bunch!

Astronomers using data from the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX) have discovered tens of thousands of gigantic hydrogen gas halos, called “Lyman-alpha nebulae,” surrounding galaxies 10 billion to 12 billion years ago. from Universe Today https://ift.tt/beO9mpz via IFTTT

What Happens When Light Goes Boom? Part 1: The Scientist Who Stared at a Glow

In 1934, a Soviet physicist named Pavel Cherenkov shone gamma rays into a bottle of water and noticed a faint blue glow. So had others before him. They all shrugged and moved on. Cherenkov didn't. What he found — by refusing to dismiss something he didn't understand — turned into one of the most useful phenomena in modern physics. from Universe Today https://ift.tt/8mvxQVX via IFTTT

Where's the Dividing Line Between A Star and A Planet? Ask the JWST.

It's obvious that Earth is a planet. It's obvious that the Sun is a star. But for substellar objects like brown dwarfs, it's not so clear. Researchers are using the JWST to find a stronger dividing line between star and planet that depends on how they formed. from Universe Today https://ift.tt/zWaP4wL via IFTTT

JWST Sees Smoking Gun for Black Hole Mergers in the Virgo Cluster

A pair of dwarf galaxies in the giant Virgo Cluster show what can happen when these stellar cities interact. Scientists at the University of Michigan focused the James Webb Space Telescope (JWST) onto the galaxies NGC 4486B and UCD736 and found each of them sporting "overmassive" black holes at or near their hearts. Those supermassive black holes comprise a large fraction of each galaxy's mass. from Universe Today https://ift.tt/iwOzUsM via IFTTT

The Incredible Shrinking Neutrino.

They are the most abundant particles in the universe, yet we barely know they exist. Neutrinos stream through everything, through walls, through planets and even through you…. in their billions every second, leaving no trace. We've known for decades that they have mass, but pinning down exactly how much has defeated physicists for years. Now, the most sensitive experiment ever built has pushed our knowledge to a new frontier, and what it found raises a profound question about why these ghostly particles are so extraordinarily light. from Universe Today https://ift.tt/bvLVwyr via IFTTT

The Universe’s Most Powerful Telescope.

When a massive star explodes on the far side of the universe, the light from that explosion normally fades long before it reaches us. But occasionally, the universe conspires to help. A newly discovered supernova has been caught using the gravity of an entire galaxy as a natural magnifying glass, boosting its light by at least a hundred times and revealing a stellar death that would otherwise have been completely invisible. It is the most magnified supernova ever found, and it opens a remarkable new window onto the distant universe. from Universe Today https://ift.tt/lb9H1vS via IFTTT

The Zhamanshin Impact Event Was Likely Much More Destructive Than Thought

Around 900,000 years ago, an impactor slammed into modern-day Kazakhstan and excavated a crater about 14 km in diameter. It was the most recent hypervelocity impactor powerful enough to trigger a nuclear winter, but not an exinction. New research suggests the crater is almost twice as large, showing that the energy released by the impact was much greater than thought. from Universe Today https://ift.tt/xmdqskY via IFTTT

Two Monsters, One Galaxy, and a Collision 100 Years Away!

Deep in the heart of a distant galaxy, two monsters are locked in a death spiral and for the first time, they have been caught them in the act.

Are Neutrinos Their Own Evil Twins? Part 2: The Weak Left-Hander

The weak nuclear force is the eccentric cousin of the four forces — the one that only shakes hands with left-handed particles. That bizarre preference turns out to be absolutely critical for stars, nuclear fusion, and the existence of most matter. And neutrinos love it. There's just one problem: neutrinos appear to only exist in one handedness, which makes no sense at all. from Universe Today https://ift.tt/pHUCvRZ via IFTTT

The Chip That Could Survive Venus

Every piece of electronics ever sent to Venus has been destroyed within hours of landing, cooked alive by surface temperatures hot enough to melt lead.

Are Neutrinos Their Own Evil Twins? Part 1: So We're Going to Redefine "Particle"

A brilliant physicist vanished in 1938, leaving behind one strange, quiet paper. It described something that shouldn't exist: a particle that is its own antiparticle. To understand why that matters, we first need to rethink what a particle even is — and that means getting weird with chirality, the Higgs field, and the neutrino's stubborn refusal to follow the rules. from Universe Today https://ift.tt/pX6toEw via IFTTT

Student Team Finds One of the Oldest Stars in the Universe that Migrated to the Milky Way

Why Does Jupiter Have More Large Moons than Saturn?

The two largest planets in our Solar System, Jupiter and Saturn, have the largest systems of moons. However, Jupiter has more large moons than Saturn, which has only one. Since both planets are gas giants, the reasons for the differences in these satellite systems have long puzzled astronomers. This motivated a collaborative team of researchers from Japan and China to develop a physically consistent model that can explain this. from Universe Today https://ift.tt/cenKg9m via IFTTT

ESA Launches 7 New Missions to Supercharge Space Data Transfer

Space is getting crowded - and not just with satellites, but with the massive amounts of data they’re generating. The amount of information being generated and passed through orbit is exploding. From high-resolution Earth observation images to global maritime monitoring, it’s also become a critical link in our infrastructure. But there’s another space this growing crowd of satellites is dependent on that is also filling up fast - the radio frequency spectrum. If we want to keep expanding our orbital infrastructure, we need to rethink how we move data around. On March 30, 2026, the European Space Agency (ESA) supported a series of eight CubeSats and one specialized payload on SpaceX’s Transporter-16 rideshare mission with the overarching goals of testing high-throughput laser communication, inter-satellite networking, and in-orbit artificial intelligence processing to make space data transfer faster, more secure, and vastly more efficient. from Universe Today https://ift.tt/JdbXZtK ...

Scientists Spot a Solar Flare With Surprising Spectral Behavior

On August 19, 2022, astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very strong spectral fingerprints of calcium II H and hydrogen-epsilon lines. It was the first time these two light signatures were seen in great detail during a flare. According to computer models, those lines were stronger than expected and play a not well-understood role in how flares heat the solar atmosphere where they occur. from Universe Today https://ift.tt/f3KzLVm via IFTTT

Could We Actually Terraform Mars? A New Scientific Roadmap Lays Out the Blueprint—And the Risks

Reading the Mars Trilogy by Kim Stanley Robinson brings the benefits and pitfalls of efforts to terraform the Red Planet into sharp relief. Since the 1970s, when Carl Sagan first suggested the possibility that we could make Mars more Earth-like, that process has been a staple of science fiction. But there’s always been a significant amount of humanity that thinks we shouldn’t.

Meet Orpheus - A Hopper Mission Built To Hunt For Life In Martian Volcanoes

We’ve spent decades scratching the surface of Mars trying to uncover life there. But we’ve been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it's likely that it’s been too hostile to harbor extant life. So if we want a better shot at finding currently living life on Mars, we need to go underground.

The Habitable Worlds Observatory Will Need Astrometry To Find Life

We’re getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we’re looking at an Earth analog somewhere else in the galaxy, we have to directly image it too. That’s a job for the Habitable Worlds Observatory (HWO), a planned space-based telescope whose primary job is to do precisely that. But even capturing a picture and a planet and getting spectral readings of its atmospheric chemistry still isn’t enough, according to a new paper available in pre-print on arXiv by Kaz Gary of Ohio State and their co-authors.

Astronomers Find a Third Galaxy Missing Its Dark Matter, Validating a Violent Cosmic Collision Theory

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to simply fly apart. But now, scientists have found a string of galaxies that seem to be missing their dark matter entirely. The latest in this string, known as NGC 1052-DF9, is described in a new paper, available in pre-print on arXiv, by Michael Keim, Pieter van Dokkum and their team from Yale. It lends credence to a radical theory of galaxy formation known as the “Bullet Dwarf” collision scenario, which has been a controversial idea for the last decade. from Universe Today https://ift.tt/7mLVrZY via IFTTT
