Accidental discovery of 1st-ever 'black hole triple' system challenges what we know about how singularities form
Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.
The Milky Way could be part of a much larger 'cosmic neighborhood' than we realized, challenging our understanding of the universe
A probabilistic new map of the universe surrounding the Milky Way reveals that our galaxy is likely part of an even larger "basin of attraction" than we previously assumed.
Are there any planets in the universe that aren't round?
Earth is round, but are there any planets in the universe that aren't?
'Martian dog' and dozens of other mysterious blobs found hiding under Mars' north pole in new 'gravity map'
A new map that details gravitational anomalies on Mars has revealed 20 mysteriously dense blobs, including a dog-shaped mass, buried below the planet's north pole. And researchers have no clear idea where they came from.
NASA discovers planet-wide electric field around Earth that's shooting bits of our atmosphere into space
NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying the field could yield some vital information about how our planet's atmosphere has evolved.
Huge cosmological mystery could be solved by wormholes, new study argues
The universe is expanding at an ever accelerating rate — and tiny wormholes that bore through the fabric of space-time might be to blame, a new study proposes.
Dead stars sometimes shine again — and gravity itself may be responsible
Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests.
What would happen if a black hole wandered into our solar system?
Black holes aren't "cosmic vacuum cleaners," but what would happen if one wandered into our solar system?
Gravity waves spark pair of perfect cloud ripples above uninhabited islands
Earth from space This 2023 astronaut photo shows a pair of perfectly aligned "wave clouds" rippling above the Crozet Islands in the Southern Ocean. The unusual patterns are the result of changes in temperature caused by gravity waves.
