Long-Period Radio Transients: A White Dwarf 'Rosetta Stone'
A 'cannibal' white dwarf in Western Australia is the 'Rosetta Stone' for a decade of mysterious long-period radio transients in the Milky Way.
Space & AstronomyThe First Weather Report From a Sunless World: JWST Maps Storms and Auroras on a Rogue Brown Dwarf
JWST captures the first detailed weather report from beyond our solar system. SIMP-0136, a rogue brown dwarf 20 light-years away, has iron-silicate clouds, 2,000 km/h storms, and auroras powered by its own magnetic field rather than a star.
Space & AstronomyWhat Scientists Found When They Turned Black Hole Collisions Into Dark Matter Detectors
Physicists analyzing gravitational wave data from black hole mergers found 27 of 28 signals matched empty-space predictions — but one did not, matching a dark matter imprint instead.
Space & AstronomyScientists Finally Know Why Mars Is Red — And What It Means for the Planet's Watery Past
A February 2025 study has overturned a century of thinking about why Mars is red, identifying water-rich ferrihydrite as the source and revealing the Red Planet once had a cold, wet climate.
Space & AstronomyCuriosity Found 7 New Organic Molecules on Mars — What It Actually Means
Curiosity found 7 organic molecules on Mars never before detected. In 3.5 billion-year-old rocks, here is what they reveal about ancient Martian life.
Space & AstronomyThe Pentagon's UFO Document Release: What the Apollo Astronaut Transcripts Actually Reveal
The Pentagon's AARO office released Apollo-era transcripts describing astronaut sightings of unexplained lights and objects near the Moon. But the gap between what the documents say and what headlines claimed is substantial. Here is what the evidence actually supports.
Space & AstronomyThe 'Moon Joy' Moment: How Artemis II's Historic Crew Reignited Global Space Optimism
Artemis II's diverse crew sparked a global 'Moon Joy' wave. Victor Glover became the first Black astronaut to orbit the Moon, reigniting public enthusiasm for human spaceflight.
Space & AstronomyA grapefruit-sized quantum device mapped Earth magnetic field from space
A device roughly the size of a grapefruit has proven it can map Earth's magnetic field from space. OSCAR-QUBE, a 10-centimeter cube built by students at Hasselt University in Belgium, operated aboard the International Space Station for 10 months starting in August 2021, and its measurements...

Space & AstronomyAtmosphere Discovered on Tiny Icy World at Edge of Solar System Defies All Predictions
At 43.7 astronomical units from the Sun, a world half the size of Pluto is holding onto something it should not possess: an atmosphere. Quaoar's discovery has planetary scientists rethinking everything they thought they understood about how small, icy worlds at the edge of our solar system behave.
Space & AstronomyCuriosity Rover Finds 7 New Organic Molecules on Mars, Including Compounds Tied to Life Building Blocks
NASA's Curiosity rover has identified seven never-before-seen organic molecules in a Martian rock sample, including compounds tied to the chemistry of life. The discovery, using a new laboratory technique aboard the rover, represents the most diverse haul of organic molecules ever found in a single sample on Mars.
