No Spin, No Explanation: A Massive Ancient Galaxy Sits Still
A rare non-rotating galaxy spotted by the James Webb telescope. One dramatic collision might explain it.

A World Beyond Pluto Burped Up an Atmosphere
An icy rock out past Neptune is holding onto gas it has no right to hold.
An Unknown Object Has Been Keeping a 44-Minute Clock. Astronomers Just Found Out It Has Two Hands.
It has pulsed every 44 minutes for longer than anyone has been watching. Astronomers just found a second signal running in perfect sync — and the physics for it doesn't exist yet.
A Planet 140 Light-Years Away Is Shedding Itself Into Space, One Mountain at a Time
A world is disintegrating as it orbits too close to its star. Each lost fragment speeds up the collapse.
A Vampire Star Exploded Twice. The Wreckage Shows Both Blasts.
The wreckage of a double-detonation supernova 60,000 light-years away just gave astronomers the first image of a stellar death that happened twice.
A Planet Had a Growth Spurt to the Tune of Six Billion Tonnes Per Second
A rogue planet with no star just consumed gas and dust at six billion tonnes per second, the highest accretion rate ever recorded for any planetary object.
A Star in Andromeda Skipped the Explosion
One of the most luminous stars in Andromeda quietly collapsed and became a black hole — no explosion, no warning.
The Dark Matter Answer May Have Arrived From Before Time Began
The invisible glue holding galaxies together may be wreckage from a universe that died before ours began. Could dark matter predate the Big Bang itself?
Space Sent Bigger Fireballs in March. People Noticed.
Double the fireballs. Rocks through roofs. Sonic booms every three days. Scientists have ruled out meteor showers, camera effects and AI. What's left?
Mars Volcano Is Changing the Planet
A planet declared geologically dead for billions of years may have an active mantle plume.
Something Invisible Is Warping Space. No Current Dark Matter Model Explains It.
An invisible object weighing a million suns is warping space 11 billion light-years away — and every dark matter model we have fails to explain it.
A Dead Galaxy Is Screaming Radio Signals Into Space. It Shouldn't Be.
A galaxy that stopped making stars billions of years ago is firing off intense radio bursts — and the leading explanation involves ancient stellar corpses finding each other in the dark.
A Supermassive Black Hole Just Went Dark on a Human Timescale
The models said this would take thousands of years. A galaxy 10 billion light-years away apparently didn't get the memo — and now the whole framework is in question.
