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...

Monster Galaxy Found
2012-10-25 22:05:33

Lee Rannals for redOrbit.com — Your Universe Online A team of astronomers has grabbed an image of a huge elliptical galaxy with a core that is bigger than any seen before. The team used the Hubble Space Telescope to collect the image of the galaxy, which is about ten times the diameter of the Milky Way galaxy. The galaxy is a member of a class of galaxies with an unusually diffuse core filled without a concentrated peak of light around a central black hole. Viewing the core...

Astronomers Measure Black Hole Radius
2012-09-27 19:16:53

Lee Rannals for redOrbit.com — Your Universe Online An international team of astronomers was able to measure the radius of a black hole for the first time. Researchers measured the radius of a black hole at the center of the galaxy M87, which lies about 50 million light-years away from the Milky Way. M87 has a black hole 6 billion times more massive than the Sun, and the team was able to observe the glow of matter near the edge of the black hole, or the "event horizon," using...

Planets Can Form In The Center Of Violent, Unstable Galaxies
2012-09-12 14:05:07

April Flowers for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. The center of the Milky Way seems like the last place to form a new planet, inhospitable and violent even. Stars crowd each other, whizzing through space like cars on a rush hour freeway while supernova explosions blast out shock waves and bathe the region in intense...

Black Holes Abound - In The Millions
2012-08-29 14:25:38

Lee Rannals for redOrbit.com - Your Universe Online Millions of black holes have been discovered, as well as extreme galaxies called hot DOGs using NASA's Wide-field Infrared Survey Explorer (WISE) mission. The telescope has helped reveal millions of dusty black hole candidates throughout the universe, and about 1,000 dustier objects that are thought to be the brightest galaxies ever found called dust-obscured galaxies, or hot DOGs. "WISE has exposed a menagerie of hidden objects,"...

Massive Winds Driven By Intense Star Formation
2012-08-22 05:30:05

April Flowers for redOrbit.com - Your Universe Online Fueled by an intense burst of star formation, fierce galactic winds may blow gas right out of massive galaxies, which in turn could shut down their ability to make new stars. A team of astronomers sifted through images and data from three telescopes to find 29 objects with outflowing winds measuring up to 2,500 kilometers per second, an order of magnitude faster than most observed galactic winds. "They're nearly blowing themselves...

When Massive Stars Collide, Monsters Are Formed
2012-08-07 13:31:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers now believe the "monster stars" located in the nearby galaxy the Large Magellanic Cloud (LMC) were formed through the merger of lighter stars. The team wrote in the journal Monthly Notices of the Royal Astronomical Society that the group of stars may have formed while smaller stars were in a tight binary system. In 2010, scientists discovered these supermassive stars, one of which is more than 300 times the mass of the...

X-ray Signal Detected During Black Hole's Destruction Of Passing Star
2012-08-03 15:48:00

[Watch Video] Lee Rannals for redOrbit.com — Your Universe Online Astronomers have identified an X-ray signal that followed an observation made last year of a quiescent black hole in a distant galaxy. The black hole discovered by the team last year was seen erupting after shredding and consuming a passing star. Astronomers then witnessed days following the observation a distinctive X-ray signal that comes from matter on the verge of falling into the black hole. This...

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...
