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 number ...

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.

About 650 light-years from here, in the constellation Aquarius, lies the planetary nebula Caldwell 63, commonly known as the ...

The James Webb Space Telescope has investigated an exoplanet that’s super cool — literally. The huge planet, which is six ...

White dwarfs—stellar remnants left after stars exhaust their fuel—offer another intriguing possibility. About 97% of stars in the Milky Way will eventually become white dwarfs.

The trailer for the dark fantasy horror film The Death of Snow White shows how it's not a Disney film with its bloodthirsty ...

Results of the new observations, published April 9 on the arXiv preprint server, indicate that the system harbors a massive pulsating white dwarf. Cataclysmic variables (CVs) are binary star ...

Spade mentioned that Snow White was involved in certain problems because of the dwarfs, and seemingly referred to the casting process of the same as he stated: “There’s seven jobs out of the t ...

Astronomers have discovered a pair of white dwarf stars located about 150 light-years from Earth that are on course to collide and produce a Type 1a supernova in approximately 23 billion years.
