Hypervelocity stars (HVS) are celestial bodies moving at speeds sufficient to escape the Milky Way's gravitational pull, with a primary proposed origin involving binary star interactions with the ...

A rare supernova let scientists glimpse a star's interior, revealing a dense silicon-sulphur shell and unexpected helium that should have vanished earlier. (Nanowerk News) An exploding star has given ...

The supernova was the death of a red supergiant star 500 times larger than the sun, in a galaxy just 22 million light-years away. When you purchase through links on our site, we may earn an affiliate ...

Astronomers have seen a lot of stars explode, but one unusual stellar death is forcing them to rethink what they thought they knew. In 2021, a star about 2.2 billion light-years away ended its life in ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...
