JWST Photographs Possible Giant Planets Around White Dwarfs
JWST has directly imaged two giant exoplanets orbiting white dwarf stars. This discovery may reveal the fate of our solar system.
A Jekyll-Hyde White Dwarf
The white dwarf J2033 seems to switch rapidly between two compositions.
Ancient White Dwarf Hosts Planetary Graveyard
Scientists have discovered one of the oldest planetary graveyards in the Milky Way: a cool white dwarf "polluted" with rocky debris.
A Strange White Dwarf with a Chaotic Past
New observations show that both rocky and icy worlds fell onto a white dwarf, indicating past orbital chaos in the system.
Astronomers Watched a White Dwarf Turn into a Thermonuclear Fireball
Astronomers have spotted the X-ray flash that precedes a nova. The brief flare is the first sign of a white dwarf erupting into a nuclear-fusion fireball.
60-second Astro News: White Dwarfs Still Burn, Black Holes Merge
This week in astronomy news, we learn that some white dwarfs still burn and image X-rays from black holes almost 12 billion light-years away.
Moon-size White Dwarf Is the Smallest Ever Found
Astronomers have discovered a white dwarf only slightly bigger than the Moon, making it the smallest ever found. It might even be on the edge of collapse.
Planet-eating White Dwarfs, A Black Hole Cluster & The "Farfarout" Object
This week in astronomy news, astronomers found planet-eating white dwarfs, a cluster of black holes, and a "farfarout" object that's now the most distant known in the solar system.
Giant Planet Found Around a White Dwarf
Astronomers have found a Jupiter-size planet orbiting a much smaller white dwarf. The discovery shows what a system might look like after its star's death.
60-second Astro News: White Dwarfs & Hot Jupiters
This week in astronomy news: Space telescopes show us that white dwarfs are crystallizing in their cores and cloudy night skies are universal among hot Jupiters.
Shockwaves Light up Stellar Explosions
Thermonuclear power sets off a type of stellar explosion known as a classical nova. Now, new research explains the mechanisms that cause these blasts to light up.
Historical Observations Reveal Ancient Nova
Astronomers and historians pinpoint the source of a 15th-century classical nova. It’s currently regathering strength.
The White Dwarf That Survived
A peculiar white dwarf could be what’s left after a failed supernova explosion.
