Using the James Webb Space Telescope (JWST), astronomers have performed infrared observations of a planetary debris disk ...

White dwarfs are the compact remnants of stars that have stopped nuclear burning, a fate that will eventually befall our sun.

A new study from Kyoto University has shown that white dwarfs, can be significantly hotter than expected when locked in tight ...

Old binary star systems may contain stars that are even hotter than scientists previously believed. White dwarfs are the dense, compact remains left behind when stars exhaust their nuclear fuel, a ...

Astronomers using the Hubble Space Telescope have uncovered the remains of a frozen, Pluto-like world being devoured by a distant white dwarf star.

Astronomers using the Hubble Space Telescope have observed a white dwarf - a highly compact stellar ember - that appears to have gobbled up an icy world akin to the dwarf planet Pluto, a finding with ...

If you're worried about climate change, rising authoritarianism worldwide, or widespread automation replacing workers, take heart--in a few trillion years (ok, more like 10 10 3 years) heat death of ...

Ten billion years ago, a star in the Milky Way known as WD J2147-4035 collapsed into a smoldering core. This stellar ember was surrounded by a thin atmosphere made of the remnant hydrogen and helium ...

The sharp vision of Hubble’s Advanced Camera for Surveys uncovered the speedy white dwarfs in the ancient globular star cluster NGC 6397, a dense swarm of hundreds of thousands of stars. Before the ...

A white dwarf star has been spotted 'switching on and off' in just 30 minutes. Astronomers say the event has previously only been seen to happen over a period of days and months. Using data from ...

Researchers have discovered an unusually massive white dwarf star that may have formed when two white dwarfs merged together. These objects are the small, dense remnants of stars nearing to the end of ...
