Scientists have measured a fundamental property of a supermassive black hole—how fast it spins—by measuring a star slamming into it. It can be hard to measure black holes unless they actually ...

The search for dark matter requires all the best models, theories, and ideas we can throw at it. A new paper by Julia Monika ...

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

In the galaxy GSN 069, a star has survived a close encounter with a black hole, ending up in orbit around it. Material pulled off the star turned it from a red giant into a white dwarf, and in ...

We’ve studied pairs of black holes merging, neutron stars colliding into one-another, and now, we may have finally witnessed signs of a black hole slamming into a neutron star.

A black hole devouring a star (NASA/Goddard Space Flight Center/CI Lab)So it's a little disturbing thinking about a star getting shredded to bits with the same ease someone chomps into a stringy ...

When a massive star expends its fuel, its core collapses into a dense object and sends the rest of its gas outward in an event called a supernova. What’s left is mostly neutron stars or black holes.

When a black hole devours a star, some of the celestial material that makes up the star occasionally gets flung out back into space, which astronomers liken to black holes being messy eaters, the ...

The supermassive black hole, located 300 million light-years from Earth at the core of the galaxy ESO 583-G004, snared and shredded the star after it wandered too close, sending out a powerful ...

The black hole is ripping apart an unfortunate star, stretching it like taffy and shaping the "leftovers" into a stellar donut the size of the solar system before feasting on this cosmic ...

A black hole in a galaxy not far from Earth gobbled up a star like it was a big, exploding noodle, and astronomers got a front-row seat to the action.. The "unfortunate star," as the researchers ...
