Astronomers have finally caught a dying star in space going out with a bang — and then another bang. The new photographic ...

About 8,150 light-years from Earth, a white dwarf star named Gaia22ayj has intrigued astronomers. Its unusual behavior, ...

Astronomers have discovered a white dwarf star, or the burnt core of a dead star, that has two completely different faces. One is made of hydrogen, while the other is made of helium.

Astronomers have captured the first-ever visual evidence of awhite dwarf star exploding twice in a remarkable supernova event ...

Astronomers have discovered an unusual blue-tinted white dwarf star with two distinct "faces": one side is hydrogen and the other side is helium, according to a new paper published in the journal ...

Scientists have discovered two rare white dwarfs—which are among the dimmest stars in the universe—that feature changes in their surface composition caused by magnetic fields. This brings the ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

Scientists have discovered that some "dead" white dwarf stars hide a metaphorical fountain of youth beneath their skin that helps them delay their cooling processes. Skip to main content.

White dwarfs typically have a radius just .01 times that of our own sun, but their mass is about the same. Stars like our sun fuse hydrogen in their cores into helium.

White dwarfs are among the most compact objects in the cosmos, though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf.

Another white dwarf, ZTF J0923+4236, dimmed irregularly every couple of months, while a third named WD 1145+017 was seen in 2015 to have variations in transits of orbiting objects, which have ...

Our Sun will become a white dwarf in about 7 billion years. At that point, it will no longer produce energy through nuclear fusion, having exhausted its fuel (hydrogen and helium). Just like the ...
