A remarkable black hole, located 270 million light-years away in the Draco constellation, has become the center of ...

Essentially, her team witnessed the birth of jets from a supermassive black hole, in real time. Meyer is lead ... thinks the orbiter is a 0.1-solar-mass white dwarf — the superheated, compact ...

While black holes suck in light, white holes gush light outward. Objects cannot avoid being pulled to the center of a black hole, but would not be able to reach the center of a white hole.

"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 ...

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 ...

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 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 ...

At that time, it began emitting radio waves at 60 times the previous intensity over just a few months, behavior which has never been monitored in real time for a supermassive black hole. Imaging also ...
