How asteroids may have sparked life on Earth

Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal systems by cracking the planet's crust and allowing hot water to flow through it. These long-lasting, life-friendly environments may have covered much of the early Earth, turning cosmic destruction into an unexpected opportunity.

Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than what human-made accelerators can produce.

Scientists are Teaching Shrimp to Eat in Microgravity for Future Moon Bases

As far as we know, food doesn’t exist naturally in space. We have to bring it with us if we want to explore the final frontier. One of the oldest and most common types of food on planet Earth is seafood, yet we know surprisingly little about how aquatic animals would react to the microgravity environment they would experience in space. A new paper by researchers at Japan’s Okayama University of Science, which was recently published in Microgravity Science and Technology, hopes to tackle that question. It used a novel way to simulate microgravity to watch how crustaceans would react to the space environment, and found that they could likely be good candidates as part of a future space food chain.

Why scientists fear we're missing evidence of extraterrestrial life

Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives. The researchers say future missions should focus not only on finding life, but also on understanding how signs of life could be missed.

Asteroid with unexplained orbital shift turns out to be a 'dark comet'

Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. As gas escapes the body of the comet, it also acts as a tiny thruster, subtly changing the comet's path.

Asteroid breakup may explain inner solar system bombardment 800 million years ago

A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological consequences on Earth. The research suggests that the catastrophic breakup of the Eulalia parent body could be linked to an impact shower that struck the terrestrial planets about 800 million years ago. The work is published on the arXiv preprint server.

Are we missing the universe's 'noosignatures?'

Astrobiology has long been split into two camps: a search for "biosignatures" and a search for "intelligence." These look for very different things, but they also leave a huge gap in between. It took 3.5 billion years for us to go from the first microbe to a civilization that sent radio waves into the cosmos. Detecting life in between those stages is a relatively untouched aspect of astrobiology—which is also the focal point of a new paper, "Signs and Signatures of Intelligence," available on the arXiv preprint server, by astrobiologist Julia DeMarines.

Roman telescope will spot distant black holes that shred stars

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. New research suggests NASA's Nancy Grace Roman Space Telescope, which is on track to launch Aug. 30, 2026, will be able to detect these distant, ancient black holes that existed up to 11 billion years ago.

To Measure a Black Hole’s Ultimate Spin, We Have to Go to Space

Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly at that. Determining just how quickly is key to understanding how they impact their immediate vicinity, but also the galaxies that surround them. A new paper by Tegan Thomas of the University of Virginia and her colleagues, available in pre-print on arXiv, has some good news and bad news on that front. The bad news is we currently can’t determine how fast black holes are actually spinning. The good news is that, hopefully in the next few years, we will have a new tool that will allow us to.

Astronomers Find New Features Hiding in the Orion Nebula

A team of researchers used the world's largest single-dish telescope and an interferometer to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest maps ever made of neutral hydrogen in Orion, the closest region of massive star formation. The findings expose the complex relationship of star-forming regions with their environment and suggest that the Orion Nebula has been shaped by multiple episodes of stellar feedback rather than a single expanding bubble.

Astronomers are Hunting Down the Elusive Population III Stars

It’s hard hunting down the oldest stars in the universe. These behemoths, known as Population (or Pop) III stars, are a missing link in cosmology between the primordial soup that was the early universe and the complex, “metal”-rich cosmos we’re familiar with today. But we’re slowly getting a better idea of where to look for them, and a new paper available in pre-print on arXiv from Alessandra Venditti of the University of Texas at Austin and her co-authors, highlights some of the recent advances and potential new surveying techniques that could eventually help us definitively find these massive, bright, early sparks in the universe.

There are parts of the universe that are extremely hard to see, even for our most advanced telescopes.

Magnetic fields are even harder since regular light typically passes right through them. However, according to a new paper available in pre-print on arXiv, by Manisha Caleb of the University of Sydney and their co-authors, we’re currently commissioning a potentially game-changing new tool that could use a particularly violent astronomical phenomenon to provide new insight into these hard to see places.

Gravitational waves reveal hidden populations within black hole mergers

Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a catalog that now numbers in the hundreds. Yet despite this wealth of data, a fundamental question has remained stubbornly unresolved: How do these black holes actually form?

Earth may have been seeding Venus with life for billions of years

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—it may have come from Earth.

Could Permanent Magnets Protect Astronauts from Solar Storms?

Shielding astronauts from the killer radiation they face is a central challenge facing any designer of a deep-space crewed mission. Even relatively low levels of exposure for long periods of time can lead to everything from central nervous system damage to cancer. But current solutions, such as passive water shells or active superconducting magnets, have their own limitations. To get around those, a new paper, available in pre-print on arXiv by Valerio Parisi and a team of researchers from Italy and Germany, looks at the feasibility of using a permanent magnet (and its associated permanent magnetic field) to potentially block some of that deadly radiation without the costs of competing technologies.

NASA Is Calling on Industry to Build Its Lunar Infrastructure

NASA is serious about going back to the Moon. Ongoing missions like the recently completed Artemis II trip around the Moon are just one such sign. But perhaps more importantly, NASA is recognizing how much additional work will have to go into funding technology development if we hope to stay on the lunar surface permanently. To reflect that understanding, the agency recently released a request for public feedback on what it calls the Lunar Enabling Infrastructure Accelerator - which might have been named after a Star Wars fan, since its acronym is LEIA.

A "Smart Ruler" Could Help Swarms of Space Telescopes Image Exoplanets

We’ve talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings - at least as long as we’re not sending them 500+ AU away to a gravitational lensing point. We’ve also talked at length about the potential solution to that problem - interferometry, where multiple smaller satellites link up precisely, but are spaced far enough apart to act as one gigantic mirror. The problem is, from a technical standpoint, it’s really hard to build these kinds of systems. But the field has taken another step forward with a new paper from researchers at Xidian University and the Beijing Institute of Control Engineering, published in Space: Science & Technology, which describes a system to both control and calibrate a free-floating interferometer.

Black hole collisions may follow entropy law, offering simpler remnant predictions

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits gravitational waves—ripples in the fabric of spacetime—that are strong enough to be detected with precision instruments on Earth even when they originate billions of light-years away.

Meteorite reveals a lost moon-sized world from the dawn of the solar system

A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story.

Future astronauts could walk across rocks from deep inside the Moon

A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike from a large, iron-cored object blasted material from deep inside the Moon, including mantle rocks.

Much of Earth's 'space dust' may come from unidentified near-Earth asteroids

Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way to obtain samples to study our cosmic neighbors. However, it can be difficult to determine which objects certain samples originated from if their parent bodies aren't already in available catalogs. A recent study, published in Science Advances, describes a new subset of space dust with such mysterious origins and how researchers are tracking down potential sources.

Scientists thought the universe was uniform. New evidence says otherwise

What if one of the biggest assumptions in cosmology is wrong? New research suggests the universe may not be perfectly uniform in every direction, as scientists have long believed. A puzzling mismatch known as the cosmic dipole anomaly shows that the distribution of distant galaxies and quasars doesn’t align with patterns seen in the leftover glow of the Big Bang. If confirmed, this discrepancy could undermine the foundation of the standard model of cosmology and force researchers to rethink how the universe is structured from the ground up.

Discrepancies in AI lunar crater catalogs discovered

A new Southwest Research Institute-led study compared eight AI-generated lunar crater catalogs, discovering that many of their published performance metrics drop sharply when the databases are evaluated using the same scientific standards humans are held to. Crater catalogs provide a comprehensive record of impact craters on planetary surfaces. They log the precise location, dimensions and physical characteristics of impact structures to help scientists understand the geological history of the solar system and its components.

Black holes buried in mysterious 'little red dot' galaxies could blast cosmic ghosts at Earth

Mysterious "little red dots" discovered in the early universe by the James Webb Space Telescope could harbor buried black holes that fire high-energy neutrinos through the cosmos.

More: Neutrinos are referred to as ghost particles because as chargeless and near-massless particles, hundreds of trillions of them stream through your body every second at nearly the speed of light. Plus, the source of high-energy neutrinos frequently detected on Earth is something of a mystery.

The Square Kilometre Array Will Revolutionize the Hunt for Alien Life

With new technologies come new opportunities. And that is especially true in astronomy - with every new advanced telescope we have the potential to see (or in some cases, listen) further and more clearly than we ever have before.

Astronomers Spot an Extremely Rare Galaxy Mega-Merger

Scale in the universe is hard to understand from a purely human perspective. Many times the math just doesn’t sit well with our brains that evolved to capture and process data about the world around us rather than groking the complexities of stellar dynamics and galaxy mergers. But every once in a while astronomers find something that, if we can wrap our heads around the numbers, gives a sense of just how big the universe is. That is precisely what a new paper, available in preprint on arXiv from a group of astronomers led by Z.L. Wen of the Chinese Academy of Sciences, hopes to do when it describes a merger of not one, not two, but six supermassive galaxies and the active dynamics they’re subject to.

Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy measure

Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, physicists have relied on complex equations from Einstein's theory of general relativity and quantum mechanics. But in the early 1970s, Stephen Hawking and other physicists found parallels between the laws of thermodynamics describing ordinary things—like how a stovetop boils a pot of water—and black hole mechanics.

Alien messages may have reached Earth without us realizing it

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to spot. The effect could be especially important around M-dwarf stars, the most common stars in the Milky Way.

A Supermassive Black Hole Gets Blamed for Quenching Star Formation

Some of the most massive galaxies in the Universe appear to be missing a lot of stars. That seems unusual, since birthing stars is one of a galaxy's main tasks as it grows. According to Xin "Cindy" Xiang of the University of Michigan, something is suppressing or quenching the births of stars in these and she thinks that black holes might be the culprit.

A Star’s Death Throes Involves a Lot of Kicking

When stars like the Sun reach the end of their lives, the textbook story has them puffing up and quietly shedding their outer layers to leave a white dwarf behind. A new model suggests it is far less serene than that. As dying stars eject mass asymmetrically, each burst delivers a tiny recoil, and over hundreds of thousands of years roughly ten thousand of these kicks add up to send the star drifting through space at a respectable speed. The idea neatly explains why wide binary star systems tend to fall apart once one star becomes a white dwarf, and it hints at something more dramatic still waiting to be confirmed

Galaxy Groups Hiding in the Universe’s Emptiest Places

Even the universe’s emptiest regions, the vast voids that make up most of the volume of space, are not entirely empty. A new study using the CAVITY survey hunts for galaxy groups hiding within these voids, applying a friends of friends technique to chart how nearby galaxies cluster together despite the surrounding emptiness. The results paint a striking picture that most void galaxies actually live entirely solitary lives, yet where groups do form, they are small, loose and curiously indifferent to just how empty their void actually is. It raises a deceptively simple question that turns out to be anything but: in the universe’s quietest neighbourhoods, what makes some galaxies choose company while most remain alone?

ESA Outlines High-Tech Lander Instruments for 2050 Enceladus

Saturn’s moon, Enceladus, has become a prime solar system target for astrobiologists. This is because the small moon, which is just over 10 percent the diameter of Earth’s Moon, harbors a vast subsurface ocean beneath its icy crust. This subsurface ocean combined with the geysers at Enceladus’ south pole that discharges bits of this ocean into the void provides scientists with a treasure trove of opportunities for scientific research into whether Enceladus could harbor ingredients for life as we know it, or even direct evidence for life.

However, astronomers have also observed a few galaxies that don't fit this pattern. This is the most compelling evidence of missing Dark Matter, as its presence would increase that mass by a factor of 100.

Earth Microbes Can Survive Individual Martian Hazards—and Evade Astronaut Immune Systems

Hopefully, we’re about to travel back to the Moon relatively soon.

Humans themselves are essentially walking ecosystems, and understanding how our microbial companions survive in the harsh environments of space will be critical to ensure the health and safety of future astronauts, no matter where their giant leaps might be. A new PhD thesis from Tommaso Zaccaria at Radboud University showcases just how well-suited to some of these harsh environments terrestrial pathogens actually are.

Weaving the Future of Space Suits

The famous opening scene of the Martian has Mark Watney stabbed in the torso with a communications antenna. While this accident sets up the plot for what is widely regarded as a modern classic of sci-fi storytelling, what if he was wearing a space suit that would have stopped the impact altogether? That’s the idea behind a recent NASA Small Business Innovation Research (SBIR) Phase I program run by researchers from Materials Research & Design, Fiber Materials, Inc, and NASA’s Johnson Space Center. Their work, which was recently presented at the National Space & Missile Materials Symposium, showcased a type of advanced 3D-reinforced fabric that could have saved Watney and his compatriots a whole lot of trouble.

The Dead Stars That Won't Fade Quietly

The wreckage of an exploded star is meant to fade quietly, cooling over thousands of years like the embers of a fire. So astronomers were stunned when NASA's Chandra X-ray Observatory caught dozens of these supernova remnants in a nearby galaxy doing the opposite, flaring and flickering in X-rays as though refusing to die. In each case a star appears to have survived its partner's explosion, only to be slowly devoured by the black hole or neutron star its companion left behind. It’s a discovery that turns the calm graveyards of dead stars into something far stranger and more alive.

Ancient Martian River Channel Yields Complex Organics

Jezero Crater on Mars is a 45-kilometer-wide (28-mile) crater that once hosted a lake billions of years ago fed by two distinct river valleys with Jezero eventually forming an exit channel over time. One of Jezero’s most prominent features is the massive river delta that consists of sediments that were deposited as the inflow slowed down. Researchers hypothesize that the delta and lake were formed under freshwater conditions, indicating the potential for life as we know it, also called biosignatures.

A dying star could create a new universe instead of a black hole

What if some black holes aren’t black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the collapse could trigger the birth of a tiny new universe inside the dying star. Driven by dark energy, this miniature cosmos would expand and push back against gravity, preventing complete collapse and creating an exotic object known as a gravastar.

The "Shadow Blaster" Galaxy's Role in High-energy Cosmic Neutrinos

On September 22, 2021, the IceCube Neutrino Detector in Antarctica caught a blast of neutrinos as it passed through the solar system. These neutrinos were remarkably high-energy and came from a galaxy 11 billion light-years away. That's a period of the Universe's history known as "Cosmic Noon". It's when star formation in galaxies was at its most active and that provided an interesting clue to their origin. The source of the neutrinos was nicknamed "Shadow Blaster" because the event that created the neutrinos was hidden by a dense cloud of dust, which made it invisible to optical observations.

Giant mirrors in space have been a staple of science fiction for decades. But so far there’s been very little work looking at the actual physics behind the concept - possibly because we’re still so far from making them ourselves. Still, they could potentially serve as a passive technosignature, if we manage to find one. In order to do that, though, we have to understand what we’re looking for. That is the purpose of a new paper, available in pre-print on arXiv, by Shauna Sallmen of the University of Wisconsin - LaCrosse, and Eric Korpela of UC Berkeley.

The Black Holes That Burp Years After They Eat

When a star strays too close to a supermassive black hole, it is torn apart in a brief, brilliant flare, and astronomers long assumed that was the end of the story. It isn't. Using the Very Large Array to follow dozens of these stellar killings, a team has discovered that many black holes "burp" months or even years later, belching out streams of radio light as they fling part of their meal back into space. These delayed flares let astronomers watch a black hole's appetite change in real time, and reveal that even our Galaxy's quietest looking giants are messier, and far more active, than anyone realised.

An Island of Calm at the Violent Heart of the Galaxy

The centre of the Milky Way is one of the most violent places in the Galaxy, a churning storm of gas moving faster than sound, and about the last spot you would expect a star to be born. Yet astronomers mapping that chaos with the ALMA telescope have stumbled on a hidden pocket of calm, where the gas slows, settles and quietly begins gathering itself into the seeds of new stars. The find suggests stars may take their first steps the same way everywhere, even here, and that our own Sun was likely born from just such an island of stillness, billions of years ago.

Two Planets Lighter Than Candy Floss

Astronomers have found two of the lightest worlds ever discovered, a pair of giant planets so wispy that, gram for gram, they are less dense than candy floss. Each is roughly the size of Jupiter yet holds almost nothing inside and the two circle the same distant star as siblings, locked in a gravitational dance that sees them tug one another off schedule as they orbit. It was observations from the depths of the Antarctic winter, that let astronomers weigh them and uncover just how astonishingly insubstantial they are. Now they want to know just how a planet ends up barely heavier than air at all.

Europa’s Ice Shell Secrets Unlocked by Ground Radar Study

Jupiter’s moon, Europa, has become high-value real estate for astrobiologists and the search for life beyond Earth. This is because the small moon, which is slightly smaller than Earth’s Moon, boasts a massive subsurface ocean of liquid water that scientists estimate contains about double the amount of water of all Earth’s oceans combined. As seen on Earth, water equals life, so scientists are eager to continue to explore Europa in any way possible to determine if it could harbor life as we know it, or even as we don’t know it.

Listening to the One Place That Swallows Everything

The event horizon of a black hole should be impossible to study. It’s the point of no return, the boundary where gravity grows so strong that not even light can escape, so by definition nothing can carry word of it back to us. Yet a team of scientists have found a way to reach it and found a hidden signal, a faint trace, never read before, carrying information from the very edge of the horizon in the instant before it formed. From it they measured the new black hole's spin and surface gravity, and opened a fresh way to test whether Einstein's theory survives in the most extreme gravity there is.

Powerful Solar Storms Can Change Precipitation for Parts of North America

For decades, scientists have searched for a clear link between the Sun’s explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sharp changes in the weather — such as declines in precipitation — and the more powerful the storm, the more dramatic the shift.

Ancient stellar flyby may still be steering long-period comets today

The Gaia mission has allowed researchers to understand the motions of stars like never before, even revealing possible interactions between our solar system and nearby stars. Planetary Science Institute Senior Scientist Nathan Kaib and collaborator Sean Raymond (Universite de Bordeaux) have found that a recent stellar passage likely triggered a huge increase in comet formation as the star's gravity altered Oort cloud objects' orbits, sending them cascading into the inner solar system. We may even still be feeling the effects of this passage today. This work is being presented at the American Astronomical Society Division on Dynamical Astronomy.

Scientists find evidence of vast hidden magma systems inside Mars

Researchers from the University of Oxford have uncovered evidence that Mars once hosted enormous, Earth-like magmatic systems deep beneath its surface—despite the planet lacking the plate tectonics long thought necessary for this kind of geological complexity.

More: Mars is often described as a "stagnant lid" planet: Unlike Earth, its surface is not broken into moving tectonic plates. Because plate tectonics drives volcanism, recycling and continent-building on Earth, many scientists assumed Mars lacked the conditions needed to produce similarly complex crust.

Astronomers Catch the Glowing Shockwave of a Galaxy on the Move

Astronomers have discovered a galaxy so unlike anything in the textbooks that the researcher who found it, after 25 years studying these objects, says he has never seen its equal. Named RAD-BAARG, it is falling supersonically into a distant cluster of galaxies and ploughing up a glowing arc of radio plasma nearly 1.8 million light years across, shaped uncannily like a bow and arrow. It offers astronomers their clearest view yet of a bow shock, a structure long predicted but almost never glimpsed. And in a final twist, the first person to spot it was not a professional at all, but a student combing through telescope data from a remote hillside in the Himalayas.

How NASA Taught Four Astronauts to Read the Moon

When Artemis II swept around the far side of the Moon this April, carrying the first humans beyond Earth orbit in more than fifty years, NASA had prepared its four astronauts for something more than flying the spacecraft. It had trained them to see. Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen spent two years learning to read the Moon like field geologists, hunting through impact rocks in Labrador and volcanic ash in Iceland, so that when they finally gazed down on the terrain, they could describe its colours, shadows and history with a scientist's judgement. It’s a quiet revolution in what we send astronauts to the Moon to do, and a glimpse of how the next explorers will work when they finally land.

Uranus, Neptune May Be Magma Worlds, Not Ice Giants

Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they’ve only been visited by NASA’s Voyager 2 spacecraft in 1986 and 1989, respectively. Their “ice giant” moniker comes from longstanding hypotheses that their interiors are comprised of an icy mantle beneath their hydrogen/helium atmospheres. While Jupiter and Saturn are also comprised primarily of hydrogen and helium, Uranus and Neptune are hypothesized to have a layered structure comprised of icy elements within their interiors.

Crystalline Clocks Confirm Earth's Oldest Crater

A chip of zircon found in Western Australian rocks at a place called North Pole Dome revealed the age of Earth's oldest known impact crater. The team that found it was working on age-dating the crater, which is located in a region called the Pilbara Craton. They used mineral dating to pinpoint the exact time it was dug out by an impactor. Team lead Chris Kirkland from the Timescales of Minerals Systems Group within Curtin University's School of Earth and Planetary Sciences, said the findings help resolve a longstanding question about the timing of the impact. The results of the team's analysis of several minerals at the site, along with zircon, indicated that the North Pole Dome impact occurred at 3.024 billion years ago (plus or minus a few million years).

For a long time, astrophysicists thought that the Universe's first stars, called Population III stars, were uniformly massive. It seemed like the conditions they formed in were calm and serene, which favoured massive stars. But new research based on high-resolution simulations show that conditions were more chaotic than thought, and gas cloud turbulence means that Population III stars were not all massive. This affected the metallicity of the next stars to form.

Organic carbon detected in Bright Angel rock formation on Mars

In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously confirms the detection of organic carbon, the building blocks of life, in the same two rocks from the Bright Angel formation, and describes in more detail exactly what we can say about that organic matter.

Finding Organics on Mars Isn't Enough. ExoMars Will Look for Their "Handedness."

We’ve known for a long time that there are organic molecules on Mars. Rovers and landers keep turning them up wherever they look. But, “organic” simply means a molecule is made up of carbon and hydrogen atoms, not that it was created by life - there are plenty of non-biological processes that can create organic molecules. But there is one feature of organic molecules that can point very strongly in the direction of life or not - its chirality, and a new instrument on the Rosalind Franklin rover, planned for launch to Mars in the 2030s, just proved it can successfully look for it.

The Solar Gravitational Lens Could Map White Dwarfs and Black Holes

It feels like every few months we get to report on another academic paper coming out singing the praises of the Solar Gravitational SGL (SGL). Partly, this is due to Dr. Slava Turyshev’s astounding productivity in terms of pumping out academic articles, but partly because such a ground-breaking mission has lots of positive aspects, but also challenges that need to be addressed. A new paper, available in pre-print on arXiv from Dr. Turyshev, stresses an often overlooked feature of the SGL - how useful it can be at imaging things other than far away exoplanets.

Astronomers map a magnetic 'skeleton' funneling gas into a stellar nursery

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this process—and a leading suspect has been the role of magnetic fields, which thread through interstellar gas like an invisible scaffolding.

How solar wind forecasting will help define heliosphere's boundaries

Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as NASA's New Horizons spacecraft hurtles toward this mysterious region of space.

More: The heliosphere, a vast bubble of plasma created by the solar wind flowing outward from the sun, surrounds the entire solar system and shields it from much of the high-energy galactic radiation found in interstellar space. During solar maximum, the "turbocharged" solar wind expands the heliosphere. During solar minimum, the ebbing solar wind allows the heliosphere to contract.

A Quasar at Cosmic Dawn Flickers into View

Astronomers have detected a flickering quasar called J0439+1634 as it appeared only 850 million years after the Big Bang. That discovery raises fresh questions about black hole formation and activity in the early Universe. The flickering light of this distant cosmic lighthouse showed that black hole at the heart of the quasr has a flat, pancake-shaped accretion disk. That shape is more familiar in modern-day quasars, which leads astronomers to wonder how these objects formed so quickly in the infant cosmos?
