Astronomers using the Dark Energy Spectroscopic Instrument (DESI) on NSF’s Nicholas U. Mayall 4-m telescope at Kitt Peak National Observatory, a program...
The accretion disk orbiting Sagittarius A* is emitting a constant stream of flares with no periods of rest, according to an analysis of new data from the...
New data from NASA’s Chandra X-ray Observatory and ESO’s Very Large Telescope provide evidence that outbursts from supermassive black holes can help...
In 2018, astronomers observed that the corona of 1ES 1927+654, an actively accreting, 1.4-million-solar-mass black hole located in a galaxy around 270...
Using data from ESO’s Very Large Telescope (VLT) and Keck telescope, astronomers have discovered a binary star system in the S star cluster close to...
Messier 77 is a well-known, relatively nearby, bright spiral galaxy with a supermassive black hole at its center.
An artist’s concept of Messier 77,...
Primordial black holes have been theorized for decades and could even be ever-elusive dark matter. Still, no primordial black hole has ever been observed....
Named LID-568, this 7.2-million-solar-mass black hole appears to be feeding on matter at a rate 40 times its Eddington limit and is seen as it existed...
According to the prevailing inflationary universe theory, at the very beginning of the Big Bang, a mysterious energy drove an exponential expansion of...
The well-studied V404 Cygni, an X-ray binary hosting a low-mass black hole, is part of a wide hierarchical triple with a tertiary companion at least 3,500...
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
Astrononomers using the NASA/ESA/CSA James Webb Space Telescope have detected that GS-10578, a massive, quiescent galaxy at redshift of 3.064 (look-back...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies...
Astrophysicists with the Event Horizon Telescope (EHT) Collaboration have conducted test observations achieving the highest resolution ever obtained from...
New calculations reveal that pairs of supermassive black holes can merge into a larger black hole because of previously overlooked behavior of dark matter...
Using data from ESO’s Very Large Telescope (VLT) and other telescopes, astronomers have found evidence for an intermediate-mass black hole in IRS 13,...
Using more than 500 images from the NASA/ESA Hubble Space Telescope, astronomer have found evidence for a 20,000-solar-mass black hole at the center of...
A quasar called RX J1131-1231 resides approximately 6 billion light-years away in the constellation of Crater.
This Webb image shows the RX J1131-1231...
Cygnus X-3, an X-ray binary system located some 7,400 parsecs (24,136 light-years) in the constellation of Cygnus, represents a class of ultra-luminous...
