Astronomers theorize that a low-mass white dwarf, a compact core of a dead star about as large as Earth, could be the culprit. A cosmic mystery surrounding a black hole some 270 million light ...

Many mysteries in the universe still confound physicists and astronomers. The idea of white holes, which are hypothetical equivalents of black holes, is one of the most puzzling notions in ...

Rather than succumbing to star-shredding tidal forces, such a white dwarf would instead trickle-feed a small fraction of its matter to the black hole. This could offset the orbital energy being ...

According to the research, the strange behavior of 1ES is caused by a 'white dwarf' that came very close to the black hole. A white dwarf is the remains of a dead star and is made up of matter ...

It's believed that a dead stellar remnant, or white dwarf, could be spinning precariously on the edge of the black hole, causing the explosions of high-energy light. “This would be the closest ...

An artist's concept shows a stream of matter trails a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding a supermassive black hole. — Reuters WASHINGTON ...

The images show the Perseus Cluster and the Centaurus Cluster, each with a central black hole appearing as a bright white dot surrounded by patches and filaments of gas. In each image, a patch of ...
