The Event Horizon Telescope captured the first image of the Milky Way galaxy's supermassive black hole Sagittarius A* — our ...

Astronomers have traced the origin point of a jet of material that is thousands of light-years long emanating from the ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

A 3,000-light-year cosmic jet erupts from M87*, the first black hole ever imaged, offering a rare view of black hole activity ...

"It is amazing to see that we are gradually moving towards combining these breakthrough observations across multiple ...

"Looking out into the universe is uniquely allowing us to look back in time and piece together this beautiful cosmic story ...

But now a new study published in Nature suggests a solution to the Little Red Dots mystery. Scientists think young ...

Some galaxies eject powerful streams of charged particles—jets—from their centers into space. The prominent jet of Messier 87 ...

A newly identified quasar shows sustained growth beyond the Eddington limit, prompting new examination of accretion physics, radiation trapping and jet activity in early supermassive black holes.

An early black hole feeds too fast—yet still blasts X-rays and radio jets.

"It is exciting to think that Little Red Dots may represent the first direct observational evidence of the birth of the most ...

The most recent CSC update adds more than 400,000 unique compact and extended X-ray sources, as well over 1.3 million ...
