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 ...

NASA’s IXPE has just revealed the hidden geometry of a white dwarf’s cosmic feeding frenzy—using X-rays to see what no ...

A study of supernova remnant SNR 0519-69.0 using the Chandra X-ray telescope, Hubble and more has narrowed down its age to ...

Using NASA’s IXPE, astronomers captured an unprecedented view of a white dwarf star actively feeding on material from a companion. The data revealed giant columns of ultra-hot gas shaped by the star’s ...

White dwarf stars, like this one shown shrouded by a planetary nebula, are much smaller than stars like our Sun. NASA/R. Ciardullo (PSU)/H. Bond (STScI) The Sun will someday die. This will happen when ...

What can white dwarf stars eating their own planets teach astronomers about planetary and solar system formation and evolution? This is what a recent study published in The Astrophysical Journal hopes ...

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 ...
