Chinese researchers are poring over a puzzling gravitational wave signal that appears to defy the standard script of black ...

Astronomers may have identified the first-ever superkilonova, a massive cosmic explosion, through a gravitational wave signal ...

A team of Chinese researchers has suggested that the mysterious gravitational wave detected in 2019, known as GW190521, may ...

Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, challenging astronomers to rethink how neutron stars are born and collide.

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

In a strange turn of events, a supernova birthed twin baby neutron stars that merged to make a powerful kilonova.

Researchers are studying a rare double star explosion that could change how we understand space events. Astronomers may have seen a space event that has never been clearly confirmed before. It is ...

Columbia Professor Brian Metzger helped other astronomers interpret their observations of the unexpected stellar event.
