Michigan State University researchers have made important discoveries about the supermassive black hole at our galaxy’s center, presenting their findings based on NuSTAR X-ray data....

Baby stars circling the supermassive black hole Sgr A* at high speed resemble a bee swarm.

New findings show the black hole at the heart of our Milky Way galaxy had a late growth spurt.

The supermassive black hole at the heart of our Milky Way Galaxy is a quiet monster. However, Sagittarius A* (or Sgr A* for short) is not totally dormant. Occasionally it gobbles down a blob of molecular gas or even a star and then suffers…

"This opens up an entirely new frontier in laboratory astrophysics," astrophysicist Charles Arrowsmith said.

Observational astronomy shows that newly discovered young stellar objects (YSOs) in the immediate vicinity of the supermassive black hole Sagittarius A* located in the center of our galaxy behave differently than expected. They describe…

Ancient starlight from the earliest quasars has been captured by MIT astronomers, revealing that some of earliest “monster” black holes likely grew from massive cosmic...

The nearby quasar dubbed "I Zwicky 1" has unique qualities and is a great place to investigate extreme circumstances surrounding active galactic nuclei (AGN). Continue reading to learn more.

NASA's NuSTAR telescope found evidence of cosmic fireworks and X-ray echoes coming from the Milky Way's supermassive black hole Sagittarius A*.

Hubble has mapped the outflow "burps" of a nearby feeding supermassive black hole-powered quasar for the first time, measuring speeds of 6.5 million mph, around 8,500 times the speed of sound.

Astronomers analyzed observations of a quasar to find changes in the winds surrounding it.

Several international research groups have already confirmed the theory that there are two black holes at the center of the distant galaxy OJ 287, first suggested by astronomers at the University of Turku, Finland. A new study shows that…

Combined X-ray surveys and supercomputer simulations track 12 billion years of cosmic black-hole growth.

The discovery helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.

Several international research groups have confirmed that two black holes exist at the center of the distant galaxy OJ 287, a theory first suggested by astronomers at the University of Turku, Finland. A new study shows that satellite…

The sector has been dealt a double whammy blow in recent months

Clouds of gas in a distant galaxy are being pushed faster and faster -- at more than 10,000 miles per second -- out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy's center. It's a discovery…

By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to date of the growth of the supermassive black holes…
