Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed ...

Scientists have confirmed Albert Einstein's 100 year-old theory of gravitational waves, detected using a massive system of instruments called the Laser Interferometer Gravitational-wave Observatory ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely ...

A massive star may have burst, leaving behind two dense, dead cores, which then collided and caused another explosion ...

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

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

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, ...

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

The 26-foot-tall (8-meter-tall) cargo lander is expected to embark on its first flight during the first quarter of 2026, ...

Astronomers have found evidence for a possible first-of-its-kind "superkilonova," or a kilonova spurred by a supernova. Such an event has been hypothesized but never seen.
