The James Webb Space Telescope has captured a mid-infrared picture of Sagittarius A*, filling in a long-standing gap in ...

In our study published on October 21, 2024, in the journal Physical Review Letters, we predict the existence of a new type of black hole that would be surrounded by rings similar in shape to those of ...

Galactic nuclei images reveal how supermassive black holes interact with their surroundings using infrared telescopes.

Astronomers have identified a rare cosmic phenomenon: a supermassive black hole, known as J0410−0139, located 12.9 billion ...

Active galactic nuclei are supermassive black holes at the center of certain galaxies. As matter falls into these black holes ...

Since 2018, we've seen 1ES 1927+654 generate jets in real time and found it may have a lone white dwarf orbiting near the ...

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass ...

So, astronomers have to use clever indirect methods to figure out whether a galaxy has a binary supermassive black hole in its center. One type of indirect method involves searching for periodic ...

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

But the newfound duo, dubbed D9, suggests that some stellar pairs can, in fact, hang on near a black hole, if only for a short while. Astronomers estimate the stars are about 2.7 million years old ...

Astronomers have detected the most ancient blazar ever observed, originating from the early universe and emitting a beam of ...
