Astronomers using the Hubble Space Telescope have discovered a "ultra-massive white dwarf that formed when a white dwarf merged with another star," according to the Goddard Space Flight Center. Credit ...

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 ...

New model explains how inspiraling dead stars can explode at a rate high enough to match the number of Type Ia supernovae seen in universe A new mathematical model created by astrophysicists at the ...

The night sky might be about to gain a brand-new star thanks to a distant sun exploding violently. This far-distant stellar system is situated around 3,000 light years away from Earth and is usually ...

Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star ...

In about 7 billion years our sun will become a white dwarf, the name for a star that depleted its nuclear fuel and only shines as a remnant of what it once was. No star is ever born as a white dwarf ...

In an ancient star system expected to be stable and dormant, scientists found a 3 billion-year-old white dwarf star still tearing apart massive quantities of rock. “The rate we’ve seen rock consumed ...

Scientists have used computer modeling to show how a hypothesized type of supernova would evolve on the scale of thousands of years, giving researchers a way to look for examples of supernovae of this ...
