The Phoenix Cluster's central galaxy is about 5.8 billion light-years away and should be mostly done with star formation. Many galaxy clusters have a region of hot gas in the intracluster medium (ICM) ...

NASA's flagship space telescope captured flares from the disk of superheated material around the black hole, revealing the dynamic—and explosive—physics at our galaxy's core.

Astrophysicists have observed our central supermassive black hole. They found the accretion disk is constantly emitting flares without periods of rest. Shorter, faint flares and longer, bright flares ...

NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive ...

A new image from the Hubble Space Telescope shows a cosmic cloudscape, with clouds of dust and gas swirling in beautiful colors.

The supermassive black hole at the center of the Milky Way appears to be having a party, complete with a disco ball-style ...

New observations using NASA's James Webb Space Telescope (JWST) reveal a "unique" ongoing, rapid-fire light show.

Sagittarius A*, our galaxy's supermassive black hole, is constantly producing strange eruptions. Astronomers are using the ...

Using NASA's James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way.

The Milky Way’s central black hole, Sagittarius A*, is an unstoppable cosmic firework show, flaring with wild bursts of energy that seem to have no pattern. Using the James Webb Space Telescope, ...

S agittarius A*, the supermassive black hole (SMBH) at the center of our galaxy, is not as placid as previously thought, new observations with the JWST reveal. Instead, the surrounding accretion disk ...
