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.
Milky Way's rarest black hole may lurk behind 7 stars that 'shouldn't be there'
Seven strangely-behaving stars in the Milky Way's Omega Centauri cluster may be under the influence of an extremely rare type of black hole, new research suggests.
Study finds black holes made from light are impossible — challenging Einstein's theory of relativity
New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.
Planet Nine: Is the search for this elusive world nearly over?
Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts say.
What is the 3-body problem, and is it really unsolvable?
The three-body problem is a physics conundrum that has boggled scientists since Isaac Newton's day. But what is it, why is it so hard to solve and is the sci-fi series of the same name really possible?
A new theory of quantum gravity could explain the biggest puzzle in cosmology, study suggests
A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests.
