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

Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe.

A strange, ultra-bright flash in a distant galaxy has given astronomers their strongest hint yet that a new class of stellar catastrophe exists. The event, tagged ZTF25abjmnps and also known as ...
