The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

For the first time, researchers have simultaneously measured the gravitational waves and the light from two merging neutron stars. ‘Multi-messenger astronomy’, combining the observation of ...

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

EIRSAT-1, the student-built satellite from University College Dublin (UCD) that was launched into space last December, detected two separate gamma-ray bursts on 21 August. One of the gamma-ray bursts ...

The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers ...

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star explodes twice in violently different ways. Their analysis of a series of ...

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

Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit ...

"These extreme events stretch the bounds of our understanding of physics, and studying them allows us to learn new things." When you purchase through links on our site, we may earn an affiliate ...

New research suggests that colliding neutron stars can briefly "trap" ghostly particles called neutrinos, which could reveal new secrets about some of space's most extreme events. When you purchase ...
