Astronomers at Newcastle University and Colby College have developed a new technique to determine how likely it is that two galaxies are very close together...
Centaurus A is located 13 million light-years away in the constellation of Centaurus, and represents the fifth brightest galaxy in the sky.
This composite...
SSN 7 is a so-called contact binary located in the Small Magellanic Cloud, a dwarf galaxy some 210,000 light-years away in the constellation of Tucana....
In 2017, astronomers from the Event Horizon Telescope (EHT) Collaboration captured the first image of a black hole by coordinating radio dishes around...
Intermediate-mass black holes in the mass range between 100 and 100,000 solar masses are the missing link between stellar-mass black holes and super massive...
Messier 87, a massive elliptical galaxy located approximately 53 million light-years away in the constellation of Virgo, turns out to be triaxial, or potato-shaped,...
The iconic Event Horizon Telescope (EHT) image of the supermassive black hole at the center of Messier 87 has received its first official makeover, thanks...
The newly-discovered supermassive black hole resides in a compact star-forming galaxy around 7.7 billion years away and has a mass of 20 million solar...
Using the NASA/ESA Hubble Space Telescope and other space and ground-based observatories, astronomers have discovered SDSS J0749+2255, a closely bound...

Astronomers have provided vital information in the global effort to understand GRB 221009A, one of the nearest and possibly the most-energetic gamma-ray...
It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed...
Ultramassive black holes with extreme masses of over 50 billion solar masses can be formed in the rare events that are multiple quasar mergers happening...
In 2015, astrophysicists for the first time detected gravitational waves, ripples in space-time that occur when neutron star or black hole mergers disrupt...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
