Astronomers have identified the origin of a mysterious flash that occurred three years ago.
This week, astronomers announce a newborn magnetar and a fast radio burst that's bursting to a beat.
A massive star lost most of its mass before exploding and creating a neutron star — and a second nearby neutron star might have been the thief.
A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
New observations have helped astronomers identify the source of a 2,000-year-old supernova explosion. But this blast, and the neutron star that created it, seem to have a curious history that defies explanation.
Astronomy news this week: Hubble images the most distant star, radio telescopes combine forces to probe black hole jet, and neutron star hotspots explained.
Astronomers have discovered a newborn neutron star in a rare pairing with an old red giant companion.
Stars leave interesting messes after they die: diamond-studded puffballs, neutron stars, and black holes. We explore an example of each in June's night skies.
Scientists have been looking for decades to confirm a weird quantum effect first predicted in 1936. Have they finally found hard evidence for it?
The gravitational wave observatory has detected a second event, heralding a new era in astrophysics. The day after Christmas last year, the cosmos quietly gifted scientists with gravitational waves — ripples in the fabric of spacetime – produced in a collision between two stellar-mass black holes. It’s the second event…
Antares and Betelgeuse may be colossal stars, but we take it to the next level of stellar monstrosity with a visit to UY Scuti, a star that makes our Sun seem no bigger than a pinpoint.
