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 ...

University of Warwick astronomers have uncovered compelling evidence that a nearby white dwarf is in fact the remnant of two stars merging — a rare stellar discovery revealed through Hubble Space ...

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 ...

Astronomers have uncovered an extraordinary discovery in the cosmos: a binary star system consisting of two white dwarf stars, located just 150 light-years away from Earth. These stars are on a ...

Based on a survey of nearby galaxies, researchers conclude that type Ia supernovae—cosmology's "standard candles"—typically result from the collision of white ...

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

The ultimate cosmic "cold case" has lingered for 843 years — and now, space detectives may have solved it at last. In 1181 AD, as the Genpei War raged in Japan, a mystery "guest star" briefly flashed ...

When astronomers peer up at the heavens, they aren't just looking for objects we already know to exist. They also hunt for evidence of physical phenomena we think should exist but haven't found yet.
