Dark Matter May Have Left Its Fingerprint in a Gravitational Wave.

By Mark Thompson - May 15, 2026 07:03 AM UTC
Dark matter makes up roughly 85 percent of all the matter in the universe. We have never directly detected a single particle of it. But a new method developed by physicists at MIT and across Europe may have just opened a door we didn't know existed. When two black holes collide and merge, they send ripples through the fabric of spacetime, these are known as gravitational waves and if those black holes happened to spiral through a dense cloud of dark matter on their way in, those waves carry an imprint of it. For the first time, scientists have a technique to read that imprint and one signal in the existing data is already raising eyebrows.

Artemis III: The Mission That Has to Work Before Humans Can Return to the Moon.

By Mark Thompson - May 15, 2026 06:56 AM UTC
Artemis II has barely left the headlines. On April 1st 2026, four astronauts climbed aboard NASA's Orion spacecraft, rode the most powerful rocket ever to carry humans beyond low Earth orbit, and swung around the far side of the Moon. The world watched. Now, before the dust has settled, NASA has outlined its plans for what comes next. Artemis III won't be landing on the Moon. But what it will do is arguably just as important and if history is any guide, it's exactly the kind of mission that makes the difference between a Moon landing and a disaster.

It's Raining Stardust. It Has Been for Thousands of Years.

By Mark Thompson - May 15, 2026 06:50 AM UTC | Stars
Right now, as you read this, Earth is drifting through a cloud of debris from an ancient stellar explosion. Stardust, real stardust, is raining down on us so thinly scattered that we have only just found the proof. Locked inside Antarctic ice cores up to 80,000 years old, an international team led by the Helmholtz-Zentrum Dresden-Rossendorf has discovered traces of iron-60, a radioactive isotope that can only be created in the heart of an exploding star.

We've Been Listening for Ten Years. Here's What We Heard

By Mark Thompson - May 14, 2026 10:49 PM UTC | Astrobiology
For ten years, astronomers at UCLA have been pointing one of the world's most powerful radio telescopes at the stars and listening. Not for pulsars or gas clouds, or the hiss of the cosmic microwave background, but for something far more extraordinary. A signal from another civilisation. The result of a decade's work, 70,000 stars, and 100 million candidate signals is now in and every single one of them was us! But far from being a disappointment, the findings are among the most rigorous and revealing in the history of the search for extraterrestrial intelligence.

The Roman Space Telescope is Ahead of Schedule, and the Hubble is Giving it a Jump Start

By Evan Gough - May 14, 2026 05:28 PM UTC | Telescopes
One of the core community surveys of NASA’s Nancy Grace Roman Space Telescope, the Galactic Bulge Time-Domain Survey, is expected to locate over a thousand exoplanets that orbit far away from their stars, beyond the orbital distance of Earth from the Sun. Although Roman hasn’t launched yet, astronomers already are gathering useful supporting data by utilizing NASA's Hubble Space Telescope, which could assist astronomers in analyzing Roman data.

The Universe's Biggest Black Holes Aren't Born, They're Built

By Mark Thompson - May 14, 2026 11:04 AM UTC | Black Holes
When a massive star dies, it can leave behind a black hole. That much has been understood for decades. But the most monstrous black holes in the universe, the heavyweights detected by the faint ripples they send through the fabric of space and time aren't born that way at all. According to a new Cardiff University study, they're built through repeated, catastrophic collisions in the most densely packed star clusters in the cosmos.

The Planet That Shouldn't Exist… But Does

By Mark Thompson - May 14, 2026 10:56 AM UTC
Hot Jupiters are the bullies of the planetary world. These colossal gas giants orbit impossibly close to their stars and their gravity is so overwhelming that anything nearby gets scattered, swallowed, or flung into oblivion. Finding a smaller planet surviving inside a hot Jupiter's orbit should be virtually impossible. Yet 190 light years away, that's exactly what astronomers have found.

We've Been Wasting 99% of Our Supernova Data

By Mark Thompson - May 14, 2026 10:48 AM UTC | Stars
Every time an astronomer points a telescope at a distant supernova, they're trying to measure how far away it is. But the light from these stellar explosions arrives tangled up with interference from dust, the age of the host galaxy and the chemical make up of the original star . Unpicking it all has always been a painstaking business. Now a team of researchers has used artificial intelligence to cut through the noise in a single step, potentially making cosmological measurements four times more precise. In a universe full of unanswered questions, that's a very significant leap forward.

Forget Searching for Individual Biosignatures. Instead, Find Their Patterns

By Evan Gough - May 13, 2026 08:06 PM UTC | Astrobiology
The search for life elsewhere focuses on biosignatures. These are chemicals in atmospheres that can only be attributed to life. But despite the prowess of the JWST, finding slam-dunk proof of life on other worlds is a confounding exercise. New research suggests that rather than focus on individual chemicals, we should look for statistical patterns.

Citizen Scientists May Have Just Doubled the Number of Known Brown Dwarfs

By Andy Tomaswick - May 13, 2026 02:32 PM UTC | Observing
Brown dwarfs are notoriously difficult to find. These “failed stars” aren’t big enough to sustain nuclear fusion, and therefore aren’t as bright as more traditional main sequence stars. In fact, they’re nearly invisible in optical light, and faintly visible in infrared. But thanks to dozens of citizen scientists combing through archival infrared datasets from the Wide-field Infrared Survey Explorer (WISE), and a paper published in the Astronomical Journal detailing their work, we now have an additional set of over 3,000 candidate new brown dwarfs in our stellar neighborhood, more than doubling the total number found so far.

Psyche Spacecraft Spies Mars Ahead of May 15th Gravitational Assist

By David Dickinson - May 13, 2026 01:43 PM UTC | Space Exploration
A close flyby past the Red Planet this week will send NASA’s Psyche mission on its way towards its final destination. The mission’s closest approach to Mars occurs on Friday, May 15th, when the spacecraft passes only 4,500 kilometers (2,800 miles) from the surface of the Red Planet. That’s just 1.3 Mars radii distant, inside the orbits of Phobos and Deimos.

The Night is Disappearing and We're All Paying the Price

By Mark Thompson - May 13, 2026 09:24 AM UTC
Step outside on a clear night almost anywhere in Britain and look up. Chances are you won't see much. An orange coloured washed out glow hangs over every town and city, drowning the stars in a tide of misdirected light. Now the Royal Astronomical Society is demanding that tide be turned back, not just for the sake of astronomy, but because the evidence of what artificial light at night is doing to our health, our wildlife, and our ecosystems has become impossible to ignore. The night, it turns out, isn't just a backdrop. It's a habitat that’s more entwined with our very wellbeing and health than you can possibly imagine. And we're destroying it.

What Your Kitchen Sink Has in Common With Venus

By Mark Thompson - May 13, 2026 08:04 AM UTC | Planetary Science
Turn on your kitchen tap and watch the water hit the sink. That split second where fast, shallow water suddenly slows and spreads is known as a hydraulic jump. Now imagine the same thing happening in the atmosphere of Venus, but stretched across 6,000 kilometres of sulphuric acid cloud. Researchers at the University of Tokyo have just revealed that this extraordinary phenomenon, the largest hydraulic jump ever identified in the Solar System, is responsible for a mysterious wave that has been sweeping around our neighbouring planet for years.

Four People in a Pixel

By Mark Thompson - May 13, 2026 07:53 AM UTC | Space Exploration
When NASA's Artemis II spacecraft carried four astronauts around the Moon earlier this year, the world's largest fully steerable radio telescope was quietly watching from a quiet valley in West Virginia. The Green Bank Telescope tracked the Orion capsule across 213,000 miles of empty space with a precision that would embarrass most speedometers and what it produced isn't just an engineering triumph. It's a glimpse of how the world's most sensitive ears are becoming indispensable to the future of human spaceflight.

Were Martian Tides Strong Enough to Shape its Ancient Landscape?

By Laurence Tognetti, MSc - May 13, 2026 12:53 AM UTC | Planetary Science
You’re an anaerobic microbe sunbathing on a Martian beach billions of years ago listening to the small waves hit the shoreline as you take in the perchlorates in the Martian regolith. This is because while Mars is warm and wet, it still lacks sufficient oxygen, so anaerobic life like yourself doesn’t need oxygen to survive. You’re chilling for several hours and eventually notice the water hasn’t touched you. You remember over-hearing some otherworldly fellows who briefly landed and discussed the landscape didn’t look well formed, so they left.
