The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight ...

Astronomers have been aware of cosmic vampires, dead stars that hungrily strip plasma from victim stars, for some time. New ...

The density of the white dwarf might give it an advantage, it is not easily disrupted by a black hole weighing about one million times the mass of the Sun. Still, the X-ray observations of the ...

White dwarfs are among the most compact objects in the cosmos, though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf.

Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf.

The black hole becomes a kind of parasite: quietly embedded within the white dwarf, feeding ever so slowly. This allows the white dwarf to survive with a small "endoparasitic" black hole (EBH) at ...

Curious about the supermassive black hole at the center of our galaxy? Wondering what will happen when the Sun’s core collapses, forming a white dwarf? Explore these fascinating phenomena during this ...

Previous surveys found active black holes in just 0.5 percent of dwarf galaxies. DESI found thousands of dwarf galaxies with intermediate-mass black hole candidates (some shown). Each panel in ...

300 new intermediate-mass black holes plus 2500 new active black holes in dwarf galaxies discovered Date: February 19, 2025 Source: Association of Universities for Research in Astronomy (AURA) ...

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 ...
