Gravitational wave detectors may have picked up a signal from a mysterious object too small to be a regular black hole or ...

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 ...

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 remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including Hawking’s area theorem and Einstein’s ringdown behavior. The findings also provide ...

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

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

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