Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...

A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of colliding neutron stars known as a kilonova. Then it brightened again, shifted ...

Astronomers have spotted a distant star that seems to have exploded twice. The blast may be the first-ever known “superkilonova” — a chimera of a supernova and a neutron star merger, researchers ...

After detecting a strange combination of signals in the summer of 2025, astronomers believe they may have captured the first evidence of a unique phenomenon previously theorized, but never observed: a ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become ...
