Black hole GW190412 has been caught speeding away from its birth site at about 112,000 miles per hour (180,000 kilometers per ...

The signal indicated that the event occurred extremely far away. The masses of the objects involved also caught scientists’ ...

"We found a collision within a collision. The galaxy collision triggered a wave of star formation that, over hundreds of millions of years, led to the birth and eventual collision of these neutron ...

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

NASA astronomers using the Chandra X-ray Observatory have discovered a vast, million-degree gas bubble surrounding HD 61005, a 100-million-year-old Sun-like star about 120 light-years away. Its ...

An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger ...

Astronomers have collected evidence of a violent collision between two planets in a distant star system. The first clues of this cataclysmic event came when a rather boring star began behaving very ...

Using Event Horizon Telescope observations of M87's black hole from 2017, 2018 and 2021, "astronomers have found some changes in this now iconic image that could be caused by variations in the ...

This violent fate is rare: fewer than about 1% of stars are big enough to end their lives this way. Indeed, these dramatic explosions only occur in so-called “massive stars”. These are stars with a ...

The final dance of a black hole and a neutron star before their ultimate merger has been revealed, according to new research.

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...
