The back-to-back explosions obliterated a white dwarf that had a mass roughly equal to the sun and was located about 160,000 light‑years from Earth in the direction of the constellation Dorado ...

More Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf. This vampire ...

Recommended Videos Only two other types of objects – black holes and neutron stars – are more compact than white dwarfs. The way this white dwarf, named ZTF J1901+1458, was born also is unusual.

The remaining core is about the size of Earth, but with 200,000 times its mass. The red dwarf, in contrast, is a large, cool star with about a third the mass of our sun.

The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae, leading to the most extreme objects in the universe—neutron stars and black holes.

NASA's Hubble Space Telescope has for the first time observed a cluster of white dwarfs — the tiny, super-dense remains of burned-out stars — at the centre of the Milky Way.

It is a white dwarf star that was once "several times more massive" than the Earth's sun. It has been in the process of dying for over 4,000 years, and "will continue to change over many more ...
