A supernova remnant is supposed to be a rough neighborhood for a newborn star. Shock waves rip through space at thousands of kilometers per second.

Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in ...

In March 2026, the Einstein Probe detected a brief flash of soft X-rays emitted from a galaxy about 500 million light-years away. The flash, dubbed EP260321a, immediately triggered a worldwide ...

The aftermath of a supernova, a stellar explosion, is usually a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy Messier 83 (M83), they ...

The most detailed computer simulation yet of the turbulent motion inside an exploding star has been carried out by the world’s foremost supercomputer. The results help explain how nuclear reactions in ...
