The Case for an Antimatter Manhattan Project

November 30, 2025

Chemical rockets have taken us to the Moon and back, but traveling to the stars demands something more powerful. Space X’s Starship can lift extraordinary masses to orbit and send payloads throughout the Solar System using its chemical rockets but it cannot fly to nearby stars at thirty percent of light speed and land. For missions beyond our local region of space, we need something fundamentally more energetic than chemical combustion, and physics offers or in other words, antimatter.
Why NASA Needs Space Gardeners

November 30, 2025

Growing fresh lettuce and strawberries might sound mundane until you consider doing it on the Moon or Mars. An international team has created a roadmap for cultivating plants in space, addressing one of NASA's highest priority challenges for long duration missions. These aren't just about providing fresh food for astronauts, plants in space will recycle air and water, produce pharmaceuticals, process waste, and support mental health during years long journeys to distant worlds. With the first lunar greenhouse scheduled to operate during NASA's 2027 Artemis III mission, humanity is on the verge of becoming an agricultural species across multiple worlds.
Mars Has Static Electricity!

November 30, 2025

A team of scientists have detected electric discharges on Mars for the first time, confirming a phenomenon that was theorised for decades but never directly observed until now. The Perseverance rover's microphone accidentally captured the electromagnetic and acoustic signatures of sparks generated inside Martian dust devils, similar to the static shocks you might experience touching a metal door handle. This discovery changes our understanding of Mars's atmospheric chemistry and could explain longstanding mysteries about the rapid disappearance of methane in the Martian atmosphere, while also raising important safety considerations for future human missions to the red planet.
The Ultraviolet Mystery Inside Newborn Stars

November 29, 2025

Young stars buried deep in molecular clouds are bathed in ultraviolet radiation, but they shouldn't be. Protostars are too cold and dim to produce UV light themselves, yet James Webb Space Telescope observations of five stellar nurseries in Ophiuchus reveal its unmistakable signature affecting the surrounding gas. Astronomers tested the obvious explanation that nearby massive stars illuminate these birthplaces but subsequently ruled it out. The UV radiation must be coming from inside the star forming regions themselves, forcing a fundamental rethink of how stars are born.
The Star That Shouldn't Exist

November 27, 2025

A red giant orbiting a dormant black hole is spinning impossibly fast and contains chemistry that makes it look ancient when it's actually relatively young. By listening to faint vibrations rippling through the star, astronomers have decoded a violent secret, that this star likely collided with and absorbed another star billions of years ago, an explosive merger that left it chemically confused and rotating once every 398 days. The discovery reveals how even quiet black hole systems can have turbulent histories written in starlight.
After a Century of Searching, We May Have Finally Seen Dark Matter

November 27, 2025

Ninety five years after Swiss astronomer Fritz Zwicky inferred its existence from galaxies moving impossibly fast, researchers may have detected the first direct evidence of dark matter, the invisible scaffolding that holds the universe together. Using gamma ray data from NASA's Fermi Space Telescope, a Japanese physicist has identified a halo of extremely energetic photons around the Milky Way's center that matches predictions for annihilating dark matter particles. If confirmed, humanity has finally "seen" the unseeable.
Hong Kong's Mission to Watch the Moon Get Bombarded

November 26, 2025

In 2028, Hong Kong will launch its first dedicated lunar orbiter not to study craters or map minerals, but to monitor something far more urgent, the constant barrage of meteoroids slamming into the Moon's surface at thousands of kilometres per hour. As China prepares to build a permanent lunar research station, understanding this relentless bombardment has become a matter of safety for future astronauts living and working on the Moon.
The Strange Physics Beneath Icy Moons

November 26, 2025

Beneath the frozen shells of Saturn's tiny moons, hidden oceans might occasionally boil, not from heat, but from dropping pressure as ice melts from below. This strange phenomenon could explain the bizarre geology of worlds like Miranda and Mimas, and reshape our understanding of where to search for life in the outer Solar System. A new study reveals how these distant water worlds operate under physics unlike anything on Earth.
What Seven Decades of Hunting for Aliens Tells Us

November 26, 2025

Seven billion year old meteorites carrying DNA building blocks. Frozen water on Mars. Amino acids floating in interstellar dust clouds. After seventy years of searching, we've found the ingredients for life scattered throughout the universe but have we found life itself? A new review examines every major claim of extraterrestrial life, from ancient space rocks to UFO sightings, revealing what the evidence actually supports and where wishful thinking has filled the gaps.
The Moss That Survived Nine Months in Space

November 25, 2025

Moss spores spent nine months strapped to the outside of the International Space Station, exposed to vacuum, cosmic radiation, temperature swings from minus 196°C to 55°C, and unfiltered solar ultraviolet light. Over 80 percent survived the ordeal and returned to Earth still capable of growing into new moss plants. This remarkable resilience, demonstrated by one of Earth's earliest land plants, suggests that life's fundamental mechanisms may be far more robust in the face of space conditions than previously imagined.
Two Years of Listening to the Universe's Most Violent Events

November 25, 2025

The world's gravitational wave detectors just wrapped up their longest and most productive observation campaign, capturing 250 new collisions over two years of continuous listening. These ripples in spacetime, created by black holes and neutron stars spiralling into each other across the universe, have given scientists their first direct evidence for Stephen Hawking's 1971 theory about black hole surface areas, revealed second generation black holes born from previous mergers, and detected the most massive black hole collision ever observed. The haul represents over two thirds of all gravitational waves ever detected.
Finding 40,000 Asteroids Before They Find Us

November 25, 2025

Astronomers have just catalogued the 40,000th near Earth asteroid, a milestone that marks humanity's transformation from passive targets to active defenders of our planet. These space rocks, ranging from house sized boulders to some the size of mountains, follow orbits that bring them uncomfortably close to Earth. Each discovery adds another piece to our planetary defence puzzle, though current surveys have found only about 30 percent of the mid sized asteroids that could still cause regional devastation if they struck our world.
AI Cracks Galaxy Simulation

November 22, 2025

Scientists have achieved a breakthrough that seemed impossible just months ago, they have simulated our entire Milky Way galaxy down to each of its 100 billion individual stars. By combining artificial intelligence with supercomputer power, researchers created a model that captures everything from galactic arms to the explosive deaths of individual stars, completing in days what would have taken conventional simulations 36 years. This fusion of AI and physics represents a significant shift in how we model complex systems, with implications reaching far beyond astronomy.
The Man in the Moon Gets a New Scar

November 20, 2025

The Moon gains new craters all the time, but catching one forming is surprisingly rare. Between 2009 and 2012, something struck our celestial companion just north of Römer crater, creating a bright 22 metre scar with distinctive rays of ejected material spreading outward. While the Moon's most dramatic bombardment ended billions of years ago, this fresh impact reminds us that our nearest neighbour continues to be peppered by space rocks, offering scientists a rare opportunity to study crater formation in real time and refine our understanding of impact rates across the Solar System.
Seeing an Interstellar Comet Through Martian Eyes

November 20, 2025

When an interstellar comet tears through our Solar System at 250,000 kilometres per hour, pinning down its exact trajectory becomes a race against time. ESA astronomers achieved something unprecedented in October 2025, using observations from the ExoMars Trace Gas Orbiter to improve predictions of comet 3I/ATLAS's path by a factor of ten. By triangulating data from Mars with Earth based observations, scientists demonstrated a powerful technique for tracking fast moving objects that could prove invaluable for planetary defence, even though this particular visitor poses no threat to our planet.
The Seven Sisters Have Thousands of Hidden Siblings

November 15, 2025

Astronomers have discovered that the famous Pleiades star cluster, otherwise known as the "Seven Sisters" is actually the bright core of a sprawling family of stars spread across nearly 2,000 light years. By combining stellar spin measurements with precise motion tracking, researchers identified over 3,000 related stars and revealed the Pleiades is twenty times larger than previously thought.
The Solar System Is Racing Through Space Far Faster Than Expected

November 15, 2025

Astronomers have discovered that our Solar System is moving through the universe more than three times faster than cosmological models predict, a finding that challenges fundamental assumptions about how the universe works. By analysing the distribution of distant radio galaxies using advanced statistical methods, the team detected motion so unexpectedly rapid it earned the rare five sigma statistical significance that scientists consider definitive evidence.
Machine Learning Discovers Quasars Acting as Lenses

November 14, 2025

Astronomers have used machine learning to discover seven new quasar lens systems, arrangements where a quasar's host galaxy bends light from a more distant galaxy behind it. The find more than doubles the number of known candidates and demonstrates how artificial intelligence can unearth astronomical needles in haystacks containing hundreds of thousands of objects. A team of researchers are training neural networks on synthetic data to revolutionising the search for these rare natural lenses.
China's 900 Metre Impact Crater Rewrites Recent History

November 14, 2025

Scientists have discovered a 900 metre wide impact crater in southern China, the largest modern meteorite scar on Earth. The Jinlin crater triples the size of the previous record holder and suggests that recent extraterrestrial impacts have been far more dramatic than anyone realised.
The Rust That Could Reveal Alien Life

November 13, 2025

Iron rusts. On Earth, this common chemical reaction often signals the presence of something far more interesting than just corroding metal for example, living microorganisms that make their living by manipulating iron atoms. Now researchers argue these microbial rust makers could provide some of the most promising biosignatures for detecting life on Mars and the icy moons of the outer Solar System.
