Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now. Three years ago, scientists discovered that the Magellanic Clouds host gigantic stars with between 200 and 300 times the solar mass  of our own Sun. Before then, astronomers believed that the biggest stars in the Universe did not...

Aircraft Telescope Images Ring Of Dust Surrounding Black Hole
2013-07-10 13:34:10

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using a telescope attached to a modified Boeing 747SP aircraft have captured new images of a ring of gas and dust seven light-years in diameter surrounding the super-massive black hole at the center of the Milky Way. The team used NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) to capture images of our galaxy's circumnuclear ring (CNR), as well as a neighboring cluster of extremely luminous young stars known...

Millis, Ph.D. for redOrbit.com — Your Universe Online Click here to stream "How Stars Die And Black Holes Form": Your Universe Today Podcasts (Or right-click on the above link to download the file to your computer) Black holes are among the most exotic, mysterious and perplexing objects in the Universe. They are swallowers of light, destroyers of stars and the engines that drive our galaxies. Some believe they could even hold the key to interstellar travel and may perhaps...

Dense Cloud Defies Rules Of Star Formation
2013-01-13 09:53:05

redOrbit Staff & Wire Reports — Your Universe Online An unusually dense cloud located near the center of the galaxy does not appear to be forming any massive stars, astronomers at the California Institute of Technology (Caltech) have discovered, and that behavior has them puzzled as it appears to defy the rules of star formation. The cloud, which the researchers have named G0.253+0.016, is located in the vicinity of a supermassive black hole three millions times as massive as...

Starbursts Caught Near The Milky Way's Galactic Center
2013-01-09 10:47:01

redOrbit Staff & Wire Reports - Your Universe Online Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way, NASA officials reported on Tuesday. According to the US space agency, our galaxy´s nucleus is home to a black hole with four million times the mass of the sun. It is orbited by a large disk of dust and gas, and holds...

All Black Holes Launch Fundamentally Similar High-Speed Jets
2012-12-14 11:31:15

April Flowers for redOrbit.com - Your Universe Online It would be a mistake to think of black holes as having a uniformity of size or mass. They range from modest objects formed from the end of an individual stars' life to behemoths billions of times more massive that rule the centers of galaxies. A new study recently published in the journal Science, however, shows that high-speed jets launched from active black holes share fundamental similarities despite the mass, age or...

Chandra Eyes Most Distant X-ray Jet Ever Observed
2012-11-29 10:00:20

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory has detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth, making it the most distant X-ray jet ever observed. The jet gives astronomers a glimpse into the explosive activity associated with super massive black hole growth in the early universe. A quasar named GB 1428+4217, or GB 1428 for short, produced the jet of X-rays. The black holes at the center of most...

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...

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...
