A star dies . When a star runs out of hydrogen fuel for nuclear fusion, its core begins to collapse. It enters the final stage of its life. At that point, the outer layers of the star expand and ...

A stellar-mass black hole starts its life with a death. It’s born when a star at least 10 times more massive than our Sun runs out of fuel, having already fused hydrogen into helium, and helium ...

It’s possible that the stellar life cycle, which is so crucial to the standard model of black hole formation, had nothing to do with the creation of the oldest supermassive black holes.

Supermassive black holes shut down star formation during cosmic noon, ... As Dr. Davies told Universe Today via email, quenching is a fundamental process in the life cycle of galaxies, ...

The star in question, named WOH G64, resides in the Large Magellanic Cloud, a satellite galaxy of our Milky Way, approximately 160,000 light-years away. This colossal red supergiant boasts ...

This star, first observed in 2004, was once about 25 times the mass of our sun. Kochanek and his colleagues found that for some months in 2009, the star briefly flared a million times brighter ...

Every time this doomed star plunges through a supermassive black hole's accretion disk, it loses orbital energy and triggers a burst of X-rays. Skip to main content Open menu Close menu ...

The researchers said it appears that a spinning disk of diffuse material has formed around the SDSS1335+0728 supermassive black hole, with some of the matter being consumed.

Now, about a year later, we know it's the first tidal disruption event—meaning a star being ripped apart by a supermassive black hole—identified at visual wavelengths.
