Astronomers have discovered evidence for an extraordinarily long jet of particles coming from a supermassive black hole in the early universe, using NASA s Chandra X-ray Observatory.
If confirmed, it would be the most distant supermassive black hole with a jet detected in X-rays. Coming from a galaxy about 12.7 billion light-years from Earth, the jet may help explain how the biggest black holes formed at a very early time in the universe s history. ....

Nearby black hole Cyg X-1 more massive than thought | Space


February 24, 2021
New research suggests that the famous black hole Cygnus X-1 – first black hole ever detected and one of the closest to Earth – is farther away and much more massive than previously believed.
A new study suggests that one of the closest black holes to Earth, and the first ever detected, is both farther away and more massive than we thought.
The study – published February 18, 2021 in the peer-reviewed journal
Science – says that Cygnus X-1 is about 7,200 light-years from Earth, 20% farther away than astronomers had previously believed. Before the study’s new measurements, the black hole was believed to be about 6,100 light-years away and 15 times the mass of the sun. With an increase in distance, Cygnus X-1 is now believed to be 50% larger than previous estimates. That would make this black hole about 21 times the mass of our sun. ....
