By Will Dunham WASHINGTON, Jan 12 (Reuters) - Astronomers have observed a white dwarf - a highly compact Earth-sized stellar ember - that is creating a colorful shockwave as it moves through space, ...

The sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the sun is often thought ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

"When we saw the results, it actually fitted this long-standing question of how these hypervelocity white dwarfs formed. It was super cool." When you purchase through links on our site, we may earn an ...

A rare white dwarf merger remnant emerges in ultraviolet light, revealing thin layers of hydrogen and helium stripped away during a cosmic collision. Scientists at the University of Warwick report the ...
