"This would be the closest thing we know of around any black hole," Megan Masterson, a physicist at MIT who co-led the research, said in a statement. "This tells us that objects like white dwarfs ...

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 ...

The dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary research Sara Hashemi Daily Correspondent An artist’s concept of a white ...

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 ...

The Massachusetts Institute of Technology (MIT) team thinks that a dead stellar core, or white dwarf, daringly teetering on the edge of the black hole is the cause of increasingly frequent ...

In 2018, astronomers at MIT and elsewhere observed that the black hole's corona -- a cloud of whirling, white-hot plasma -- suddenly disappeared, before reassembling months later. The brief though ...

A white dwarf would also lose angular momentum through gravitational waves, but it also has an additional source of energy. By slowly losing its outermost material to the supermassive black hole ...

The supermassive black hole at the center of the Milky Way, called Sagittarius A*, is about four times more massive than this one. White dwarfs are among the most compact objects in the cosmos ...

It's a dead star called a "white dwarf." "This would be the closest thing we know of around any black hole," Megan Masterson, a physicist at MIT who co-led the research, said in a statement.
