What exists at the core of a black hole? A research team led by Enrico Rinaldi, a physicist at the University of Michigan, ...

From unifying quantum physics and gravity to working out what is dark matter, the universe has some deep questions that ...

Scientists are constantly unraveling the universe’s greatest riddles, but many fundamental puzzles remain unsolved. How did life first emerge on Earth? What ...

so the star core begins to collapse in on itself. If its mass collapses into an infinitely small point, a black hole is born. Packing all of that bulk—many times the mass of our own sun—into ...

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 ...

They believe the most likely culprit is a spinning white dwarf — an extremely compact core of a dead star that is orbiting around the black hole and getting precariously closer to its event ...

The change is thought to be the result of the massive black hole at its core devouring gas in its surroundings, making the galaxy light up. Massive black holes exist at the center of most galaxies ...

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 ...

An artist's concept of the supermassive black hole's mid-infrared flare. Image: CfA/Mel Weiss Astronomers have detected a mid-infrared flare from the supermassive black hole at the heart of the ...

Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.

WASHINGTON, Jan 14 (Reuters) - Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be ...
