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.

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 found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal ...

(CNN) — Astronomers have made a first-of-its-kind discovery — a white dwarf star with two completely different faces. White dwarfs are burnt remains of dead stars. Our sun will become a white ...

White dwarfs are born hot, often in the region of about 180,000 degrees Fahrenheit (100,000 degrees Celsius), although some have been found even hotter.

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.

In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of ...

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 ...

For the study, the researchers used computer models to compare Earth-like exoplanets each orbiting a white dwarf star and the main-sequence K-dwarf star, Kepler-62, both of which exhibit temperatures ...
