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...

Massive Black Hole Is A Real Heavyweight
2012-11-29 06:42:37

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have measured the mass of what may be the most massive black hole observed so far by using the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory. The black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent, according to the study published in the journal Nature. NGC 1277 is about 220 million light-years away from Earth, and is just ten percent the size and...

Thanksgiving Dinner At The Center Of The Galaxy

[ Watch the Video: The Diner at the Center of the Galaxy ] Lee Rannals for redOrbit.com - Your Universe Online NASA's NuSTAR spacecraft has detected the Milky Way's central black hole eating a Thanksgiving snack. Supermassive black holes like the one in the middle of our galaxy sustain themselves by swallowing stars, planets, asteroids, comets and clouds of gas that wander around the galaxy. The space agency's new spacecraft allowed it to take an observation of the black hole...

Black Hole Blows Giant Plasma Bubble Like A Child Blowing Bubble Gum

Michael Harper for redOrbit.com — Your Universe Online The team at ASTRON, the Netherlands Institute for Radio Astronomy, has been pointing their low Frequency Array (or LOFAR) telescope at the sky since 2010, using bands of low frequencies to observe the heavens. With LOFAR, ASTRON is able to look deep into the heavens for signals of galaxies and other far away objects that haven´t yet reached earth. Now, after using a new, international version of LOFAR, called (ILT), the...

Chandra Eyes Mini Supermassive Black Hole
2012-10-25 07:19:58

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory, along with other observatories, has identified one of the lowest mass supermassive black holes ever observed in the middle of a galaxy that one would not expect to harbor this type of beast. This suggests that this black hole, while related to its supermassive cousins, may have a different origin. Located in the middle of the spiral galaxy NGC 4178, the black hole is shown in the image from the Sloan...

Black Hole Afterburner Moves At The Speed Of Light
2012-10-23 09:02:38

[ Watch the Video: High Speed Video Of Shock Diamond ] April Flowers for redOrbit.com - Your Universe Online A supersonic jet of material that looks amazingly similar to the afterburner flow of a fighter jet is blasting over two million light-years from the center of a distant galaxy. The big difference, however, is that the jet engine responsible for this material is a supermassive black hole and the material is moving at nearly the speed of light. A new study, published this past...

Milky Way Black Hole Ready For A Snack
2012-10-23 04:05:24

Lee Rannals for redOrbit.com - Your Universe Online Scientists have determined that the black hole in the middle of the Milky Way is getting ready to devour an approaching cloud of dust and gas. The researchers used a supercomputer simulation to determine that the cloud, known as G2, could possibly survive the encounter with the black hole, but its surviving mass would be torn apart and shaped differently. They came up with six simulations using Cosmos++ computer code, requiring more...

Early Universe Was Full Of Supermassive Black Holes
2012-10-08 12:41:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered a new population of supermassive black holes in the early universe by using infrared surveys. After traveling 11 billion years, the light from supermassive black hole ULASJ1234+0907 reached Earth. This black hole has more than 10 billion times the mass of the Sun, and 10,000 times the mass of the supermassive black hole in our own Milky Way. The latest research, published in the journal Monthly Notices of...

X-Ray Nova Reveals A Black Hole Surprise
2012-10-05 15:40:26

[ Watch the Video: X-ray Nova Reveals a New Black Hole in Our Galaxy ] Lee Rannals for redOrbit.com - Your Universe Online A new stellar-mass black hole has been discovered in our galaxy by NASA's Swift satellite. High-energy X-rays emanating from a source towards the center of our Milky Way galaxy were observed, indicating the presence of a previously unknown black hole. "Bright X-ray novae are so rare that they're essentially once-a-mission events and this is the first one...

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...

penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
