After our Sun becomes a white dwarf and cools completely, what will be left? Richard LivitskiSeal Beach, California Our Sun ...

C.E, Chinese astronomers spotted a supernova and dubbed it the "guest star." The National Science Foundation’s (NSF) Víctor M ...

Astronomers theorize that a low-mass white dwarf, a compact core of a dead star about as large as Earth, could be the culprit. A cosmic mystery surrounding a black hole some 270 million light ...

"This tells us that objects like white dwarfs may be able to live very close to an event horizon for a relatively extended period of time." SEE ALSO: NASA scientist viewed first Voyager images.

When they reach the end of their long evolutions, smaller stars—those up to eight times as massive as our own sun—typically become white dwarfs. These ancient stars are incredibly dense.

Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually ...

The light output of exploding white dwarf stars, which are the stellar corpses of stars with masses around that of the sun, is so uniform that astronomers can use it to measure distances.

White dwarfs (WDs) are stellar cores left behind after a star has exhausted its nuclear fuel. Due to their high gravity, they are known to have atmospheres of either pure hydrogen or pure helium.

An artist's concept shows a stream of matter trails a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding a supermassive black hole. — Reuters WASHINGTON ...

This periodicity suggested the rotation of either a neutron star or a white dwarf. Now, a new analysis of the available data conducted by Sandro Mereghetti of the Institute of Space Astrophysics ...

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 ...
