Astronomers using the NASA/ESA / CSA James Webb Space Telescope have discovered an active supermassive black hole in CEERS 1019, a galaxy that existed...
Astrophysicists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Collaboration have found evidence for gravitational waves...
Unlike most gamma-ray bursts, which are caused by exploding massive stars or the chance mergers of neutron stars, a long gamma-ray burst event dubbed GRB...
The center of the Milky Way Galaxy hosts Sagittarius A*, a supermassive black hole with a mass of about 4 million solar masses that is very quiescent....
The newly-discovered black hole resides in the hyperluminous galaxy GN-z11 at a redshift of 11 and could have originated from a stellar mass seed at redshifts...
According to quantum mechanics, a vacuum state is populated by virtual particle pairs undergoing spontaneous creation and annihilation processes. These...
Astronomers discovered only relatively recently that black hole jets emit X-rays, and how the jets accelerate particles to this high-energy state is a...
Messier 4 is a globular cluster full of ancient stars in the constellation of Scorpius, approximately 7,200 light-years away.
Vitral et al. suspect that...
AT2021lwx occurred nearly 8 billion years ago and was more than 10 times brighter than any known supernova explosion. The event was likely caused by the...
Using the NASA/ESA Hubble Space Telescope, astronomers have captured a striking new photo of the densely packed globular cluster NGC 6325.
This Hubble...
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.

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...
