Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar ...

Astronomers have captured the first-ever visual evidence of awhite dwarf star exploding twice in a remarkable supernova event ...

Astronomers have found a remarkable pair of stars that may finally prove a long-debated theory. Described in the journal Nature Astronomy, this duo offers the strongest evidence yet that type 1a ...

Astronomers have discovered an unusual blue-tinted white dwarf star with two distinct "faces": one side is hydrogen and the other side is helium, according to a new paper published in the journal ...

RX J0648.0–4418 has a mass around 1.2 times the mass of the sun and is the fastest-spinning white dwarf ever seen, rotating once every 13 seconds or so.

When the white dwarf passes in front of its companion, gravitational lensing—the focusing of light by a massive body—magnifies the star's light very slightly.

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 ...

The center of the nebula is home to the white dwarf WD 2226-210, the dense core of a medium-mass star, which has been the source of an astronomical mystery for decades.

Astronomers have spotted two hefty white dwarf stars - highly compact stellar embers - orbiting close together that appear destined to die in an extraordinarily violent quadruple detonation.

The black hole in question is 1ES 1927+654, located around 270 million light-years from Earth, with a mass around 1.4 billion times that of the sun. 1ES 1927+654 first announced its weirdness to ...

The white dwarf - named WD 2226-210 and located only 650 light-years from Earth - might have destroyed a nearby planet. Dating back to 1980, X-ray missions have picked up an unusual reading from ...
