Astronomers have observed with unprecedented precision a massive star in the midst of cosmic feasting. This discovery offers ...

Astronomers have spotted a supermassive black hole ripping apart and devouring a star in colliding galaxies. It is only the ...

Black holes are one of our Universe’s greatest mysteries. What are they made of? What happens after they gobble something up?

Published in Publications of the Astronomical Society of Japan, their work shows that these phenomena occur when the accretion disk around the black hole abruptly contracts. The inner edge of the gas ...

The data revealed that gas from HW2's accretion disk is collapsing inward at breakneck speed, feeding the star at an ...

By observing the young star HW2 in Cepheus A, located 2,300 light years from Earth, researchers have resolved the structure and dynamics of an accretion disk feeding material to this massive star.

A star in a faraway galaxy is sending itself into a spiral of doom, repeatedly plunging through a disk of hot gas surrounding a black hole and releasing powerful bursts of X-rays in the process. Soon, ...

What lies at the heart of a black hole has puzzled physicists for decades. Now, a team led by physicist Enrico Rinaldi has ...

Black holes are infamous for being invisible. But thanks to a new technique from the Event Horizon Telescope (EHT) team, ...

Supermassive black holes are some of the most powerful engines in the universe. These giants sit at the centers of galaxies, ...

As gas, dust, and stellar material spiral inward through an accretion disk superheated to millions of degrees, this matter releases tremendous energy across the electromagnetic spectrum before ...
