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

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 strange double flash in a distant galaxy may be the first glimpse of a “superkilonova,” a cosmic one‑two punch that fuses ...

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

This image shows the glow from a kilonova caused by the merger of two neutron stars. The kilonova, whose peak brightness reaches up to 10,000 times that of a classical nova, appears as a bright spot ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
