Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.

"If you were able to stand somewhat close to the white dwarf's pole, you would see a column of gas stretching 2,000 miles ...

For the first time, a planet has been discovered orbiting a white dwarf, also known as a dead star. This exoplanet, a planet outside of our solar system, is the size of Jupiter and it's known as WD ...

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 ...

Hubble Space Telescope observations of white dwarf star G238-44 has shown that it is "consuming both rocky-metallic and icy ...

A white dwarf star is undergoing the process of turning into a “cosmic diamond” as it begins to crystalise. The lullaby “Twinkle Twinkle Little Star” talks about stars in the sky looking like diamonds ...

Astronomers recently peered deep into space and found that an old, faint white dwarf named LSPM J0207+3331, located about 145 light-years away, is still consuming the rocky remains of its former ...

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 ...
