Salty water vapour provides clues to massive star formation
... life as a white dwarf as it cools and dims. Stars above eight solar masses tend to end with a bang in a supernova explosion. If the core survives it can end up as a neutron star or contracts to become a black hole if the remaining core is much...

Astronomers find closest black hole to Earth
... begin their lives with more than about 8 times the mass of the Sun and end them in a supernova explosion that leaves behind a black hole." The discoveries of these triple systems with an inner pair and a distant...
