Red Dead Redemption: Black Holes Bully Galaxies Into Submission

Typically filled with only the oldest stars, which are relatively low in mass and appear red, giant elliptical galaxies have long baffled astronomers. These galaxies are mysteriously shut down with respect to star-forming activity

Active Supermassive Black Holes Discovered In Two Merging Galaxies
2014-01-28 13:17:31

Astronomers publishing a paper in the Astrophysical Journal say they have found that two merging galaxies have active supermassive black holes.

If most physicists claimed that the popular notion of black holes as event horizons from which light cannot escape is wrong, they would be almost immediately dismissed (and possibly even scoffed at). However, when Stephen Hawking makes such an assertion, the scientific community stands up and takes notice.

Astronomers have located one of the most powerful black holes ever discovered – a gravity-intense region of space that is located nearly four billion light years from Earth and has prevented trillions of stars from forming.

Be Star Black Hole

The black hole in question is orbiting an object known as a Be-type star, which is unusual because of its incredibly high rate of rotation.

Wormholes Driving Quantum Entanglement

Two physicists have theorized that wormholes could be the cause behind the bizarre phenomenon known as quantum entanglement.

Distant Black Holes Circling Each Other

NASA astronomers have found evidence of two supermassive black holes at the center of a remote galaxy that are locked in a fierce, circling dance.

Lightweight Black Hole Has Elegant Manners

Our understanding of how some black holes consume matter might be changed by new observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light years away.

NuSTAR Helps Scientists Hunt For Medium-Sized Black Holes
2013-11-27 15:39:33

Black holes are known to either come in masses of only about 10 times that of our sun, or the equivalent in mass of up to 10 billion suns. However, NuSTAR could be finally finding a middle ground.

Hubble Sees Old And Mysterious Cluster

The NASA/ESA Hubble Space Telescope has captured the best ever image of the globular cluster Messier 15, a gathering of very old stars that orbits the center of the Milky Way.

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....

Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...

Event Horizon -- The event horizon is a boundary beyond which information will never reach an observer. An event horizon is a mathematical construct and not a physical object and a person passing through an event horizon will not notice any odd behavior. From an outside observer however, an object passing though an event horizon will appear redder and dimmer and will appear to freeze at the moment the object passes the event horizon. An event horizon can form around a gravitational...

Black Hole -- Black holes are objects so dense that not even light can escape their gravity. They are believed to form from the gravitational collapse of astronomical objects containing two or more solar masses. Astronomical observations suggest that the center of most galaxies, including our own Milky Way, contain supermassive black holes containing millions to billions of solar masses. Black holes are predictions of Einstein's theory of general relativity. In particular, they occur...
