Colliding Galaxies Create Supermassive Black Holes

At the center of almost every galaxy we have studied is a black hole of such magnitude that the traditional black hole progenitor does not seem likely. These aptly named supermassive black holes can reach millions or billions of times the mass of our Sun.

Virtual Observatory Study Explains How Black Holes Get So Massive

Astronomers using a "Virtual Observatory" set out to study "fat" black holes that grow up to more than one million solar masses.

ALMA Observatory Reveals Black Hole's Eating Habits

New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in the high-altitude Atacama Desert of Chile have revealed new details about the powerful molecular-gas jets that stream out of supermassive black holes.

Sleeping Supermassive Black Holes Can Have Periods Of Intense Flare-Ups

Around 2 million years ago, the supermassive black hole at the center of our galaxy erupted in a blaze of glory big enough to leave a residual glow that can still be seen today.

Researchers Explain Why Supermassive Black Holes Eat Less Material Than Expected

A long-standing mystery concerning super massive black holes at the center of galaxies has been solved by a team of astronomers using NASA’s super-sensitive Chandra X-ray space telescope.

Milky Way Gas Cloud Creates Multiple Images Of Distant Quasar

Using the National Science Foundation's Very Long Baseline Array radio telescope system, astronomers have for the first time managed to capture an image of a distant quasar split into multiple images due to the effects of a cloud of ionized gas in the Milky Way.

Space Slinky Video Compiled From Hubble Images

Astronomers are hoping to gain new insight in the role that black holes play in galaxy evolution thanks to a new series of time-lapse movies compiled from over a decade’s worth of observations from NASA’s Hubble Space Telescope.

Quasar Observed In 6 Separate Light Reflections

Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...

Seyfert Galaxy -- Seyfert galaxies are spiral or irregular galaxies containing an extremely bright nucleus, most likely caused by a supermassive black hole, that can sometimes outshine the surrounding galaxy. The light from the central nucleus varies in less than a year, which implies that the emitting region must be less than one light year across. They are named for the astronomer Carl Seyfert, who studied them extensively in the 1940s. They are a subclass of active galactic nuclei....

Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
