Astronomers have captured their second-ever glimpse into a rare celestial object: a white dwarf pulsar. Pulsars are typically envisioned as spinning neutron stars — a type of stellar remnant left by ...

Gamma Cassiopeiae, the central star of the W-shaped Cassiopeiae constellation, has long stumped astronomers because of its ...

Sirius is a blue giant, which burns through its fuel quickly and lives only a relatively short period of time. Yet it has a ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

Astronomers using the Hubble Space Telescope have discovered a "ultra-massive white dwarf that formed when a white dwarf ...

"When we saw the results, it actually fitted this long-standing question of how these hypervelocity white dwarfs formed. It was super cool." When you purchase through links on our site, we may earn an ...

Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after ...

In a breakthrough study published in Nature Astronomy, researchers have discovered a new origin for some of the fastest stars ever observed: hypervelocity white dwarfs—compact stellar remnants ...

Could an ocean – likely needed to sustain life – even survive on a planet orbiting close to a dead star? When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...
