A Signal From Before the Stars

By Mark Thompson - March 27, 2026 04:27 PM UTC | Cosmology
On 12 November 2025, LIGO picked up a gravitational wave signal that stopped astronomers in their tracks. The object that produced it was too small to be any known type of black hole, smaller in fact, than our own Sun. If confirmed, it would be something that has never been directly detected before, a primordial black hole forged in the violent chaos of the first fraction of a second after the Big Bang. Now two astrophysicists believe they can explain exactly what LIGO found and why it could crack open one of the deepest mysteries in cosmology.

Hunting Moon Water With Neutrons

By Mark Thompson - March 27, 2026 04:17 PM UTC | Planetary Science
Water is the difference between a temporary visit and a permanent home. If humanity is serious about building a lasting presence on the Moon, finding usable ice near the lunar south pole isn't just a scientific curiosity, it's a practical necessity. Now NASA is sending a clever instrument that hunts for water without digging a single hole, using the behaviour of subatomic particles to sniff out hidden ice deposits up to three feet underground.

Hera Aces A Massive Engine Burn On Its Way To Didymos

By Andy Tomaswick - March 27, 2026 01:43 PM UTC | Missions
In September 2022, humanity crashed a spacecraft into an asteroid - on purpose. The objective of NASA’s Double Asteroid Redirection Test (DART) was to see if we could intentionally modify the orbit of Dimorphos, the small moonlet orbiting the larger asteroid Didymos. According to all accounts, the mission worked spectacularly, but it was a one-way trip, so our ability to see what happened to the binary asteroid system has so far been limited to ground-based telescopes. That wasn’t good enough for the planetary defense community, so they planned a follow up mission called Hera, which, according to a recent press release from its operator, the European Space Agency (ESA), just successfully completed its most dramatic deep-space orbital maneuver.

Looking For Nearby ‘Project Hail Mary’ Worlds

By David Dickinson - March 26, 2026 02:30 PM UTC | Exoplanets
It’s out. The top sci-fi draw of the year Project Hail Mary is now showing in a theater near you. The movie tells the tale of middle school teacher Ryland Grace, who is sent on a one way, last ditch mission to save humanity. The story is a refreshing take on first contact and just how different life out there could be… but are there real ‘Adrians’ or ‘Erids’ out there? A new paper published in the Monthly Notices of the Royal Astronomical Society identifies 45 rocky worlds with a potential for life, out of the currently 6,281 exoplanets known.

Ripples in Spacetime and the Universe's Most Controversial Number

By Mark Thompson - March 26, 2026 02:12 PM UTC | Cosmology
Douglas Adams famously told us the answer to life, the universe and everything is 42. Astronomers have been wrestling with their own version of that answer for years, except their number is the Hubble constant, a measure of how fast the universe is expanding, and nobody can agree what it is. Now a new study using ripples in spacetime as a measuring tools has produced a fresh value that might just help resolve one of the biggest arguments in modern cosmology.

The Star That Kept Its Secret for 50 Years

By Mark Thompson - March 26, 2026 01:58 PM UTC | Stars
Look up on a clear night and you can spot the distinctive 'W' shape of Cassiopeia with the naked eye. The middle star of that W, which has the catchy name of Gamma Cas, has been puzzling astronomers since 1866, and for the last fifty years it's been blazing with peculiar high energy X-rays that simply shouldn't be there. Now, thanks to a next generation space telescope with extraordinary precision, the mystery has finally been solved. The culprit is a hungry invisible companion, quietly feeding in the dark.

How Did Venus Become a Hellscape? 234,000 Simulations Reveal Four Possible Paths

By Andy Tomaswick - March 26, 2026 12:15 PM UTC | Planetary Science
Venus is increasingly becoming a touch point for our studies of the exoplanets, as missions like the James Webb Space Telescope (JWST)and the upcoming Habitable Worlds Observatory (HWO) begin to characterize rocky exoplanets around other stars. Understanding the difference between the evolutions of Venus and Earth, which ended up with such different results, is a key to understanding whether we might be looking at an Earth-analogue or a hellish landscape like Venus. A new paper by Rodolfo Garcia of the University of Washington and his colleagues, which is available in pre-print form on arXiv, simulates Venus’ 4.5 billion year evolution as part of the solar system to try to understand some of those differences.

Direct Confirmation Of Two Baby Planets Forming Around A Young Sun-like Star

By Evan Gough - March 25, 2026 08:15 PM UTC | Exoplanets
Astronomers have observed two planets forming in the disc around a young star named WISPIT 2. Having previously detected one planet, the team have now employed European Southern Observatory (ESO) telescopes to confirm the presence of another. These observations, and the unique structure of the disc around the star, indicate that the WISPIT 2 system could resemble our young Solar System.

The Moon That Tipped a Planet

By Mark Thompson - March 25, 2026 05:04 PM UTC
Neptune has always been something of a puzzle. The distant ice giant sits tilted at an awkward angle, although not as extreme as Uranus, that astronomers have long struggled to explain. Now new research suggests the answer may have been lurking in its own backyard all along and the culprit is Triton, Neptune's strange, rebellious moon.

Russia’s Return to the Launchpad

By Mark Thompson - March 25, 2026 04:59 PM UTC | Space Exploration
Russia has returned to orbit from the very launch pad that failed it just months ago. Following an embarrassing structural collapse at Baikonur Cosmodrome last November, repairs have been completed and a fresh cargo mission has blasted skyward. But with a space programme that was once the envy of the world now struggling to recapture its former glory, questions remain about whether Russia can truly rebuild its place among the stars.

Dedicated Amateur Beats All-Sky Surveys to Asteroid Discovery

By David Dickinson - March 25, 2026 01:10 PM UTC | Observing
The modern era of all-sky surveys including Pan-STARRS, ATLAS and now the Vera C. Rubin Observatory have given amateur astronomers some stiff competition. But many amateurs have simply upped their game, and took their quest online. The ability to access remote observatories has really helped in this regard. One recent discovery highlights this growing trend. Amateur astronomer Filipp Romanov was able to nab the fast-moving asteroid 2026 CQ3 flitting through the constellation Leo last month on the night of February 15th, 2026.

We’re getting close to launch day for Dragonfly! Engineers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have officially kicked off the integration and testing stage for the car-sized, nuclear-powered helicopter bound for Saturn’s largest moon, Titan. According to a press release for APL, after years of designing, tweaking, and testing individual components in laboratories and on computer simulations, various organizations have started testing actual hardware ahead of the mission’s planned 2028 launch.

Mars Plant Growth from Cyanobacteria-Based Fertilizer

By Laurence Tognetti, MSc - March 25, 2026 03:21 AM UTC | Space Exploration
You’re the Lead Botanist on the third human mission to Mars whose primary job involves growing food for the crew throughout the long mission. While you’re very familiar with the infamous “poop potatoes” from the 2025 film The Martian, the greatest minds in science had since devised a more efficient, and less messy, method for growing food on Mars: cyanobacteria.

Extragalactic Archaeology: A New Method To Understand Galaxy Growth and Evolution

By Evan Gough - March 24, 2026 08:07 PM UTC | Extragalactic
Galactic archaeology uses chemical fingerprints in the Milky Way to trace its formation and evolution. Now a team of researchers led by the Center for Astrophysics | Harvard and Smithsonian have employed it for the first time in a distant galaxy. This is the first example of extragalactic archaeology, and it relies on help from the powerful Illustris TNG simulations.
