The black hole, with an official name of 1ES 1927+654, is located in the distant constellation Draco. Astronomers have been monitoring the black hole for years, primarily since 2018 when the mass ...

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.

Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes—those up to billions of times heavier than the sun. The new survey is unique because it was as ...

At first glimpse, it may seem like infant stars and supermassive black holes have very little in common. Infant stars, or "protostars," haven't yet gathered enough mass to trigger the nuclear ...

"This is a promising sign that there continues to be new and exciting avenues to explore tidal disruption events and use them as probes of supermassive black holes." Astronomers have watched as a ...

Scientists have been left baffled after a massive new hole, 62 times the size of Earth, has been discovered on the surface of the sun. Graphic visualisation of NASA's Solar Dynamics Observatory ...

Jets from black holes trigger cooling in the hot gas, causing it to condense into warm filaments. These filaments then flow toward the black hole, feeding it, and the cycle repeats. Brightness ...

One supermassive black hole has kept astronomers glued to their scopes for the last several years. First came a surprise disappearance, and now, a precarious spinning act. The black hole in ...
