A recent neutron star merger has defied astronomers’ expectations, leading them to question longstanding ideas about neutron stars and the supernovas that create them. “We have to go back to the drawing board.”
By watching for a special kind of flare, astronomers have identified the fingerprints of an Earth-size planet orbiting a distant star.
After a space telescope disintegrated, astrophysicists had little hope of understanding how supermassive black holes agitate giant galaxies. Then they invented a hack.
Most every cosmologist believes the universe is flat. A new analysis argues that it’s closed.
How do magnetars get so magnetic? A study of stellar explosions shows that the long-accepted theory might be wrong.
The astronomers Michel Mayor and Didier Queloz won half of the prize for their 1995 discovery of a Jupiter-like planet orbiting a nearby star. The cosmologist James Peebles won the other half for work exploring the structure of the universe.
