Black Hole Research Nets Stephen Hawking $3 Million Prize
2012-12-11 08:41:39

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the world´s most renowned physicists has likely got something bigger on his mind now than solving puzzles of the universe. Stephen Hawking, who has been shaking up the science world more than 25 years, has won a $3 million (£1.8m) Fundamental Physics Prize for his discovery in the 1970s that black holes emit radiation, for his work in quantum gravity and for his work in quantum aspects of the early universe. The...

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...

Bright Flare In A Black Hole
2012-11-06 19:14:34

Lee Rannals for redOrbit.com — Your Universe Online A team of scientists say they have detected the brightest flare ever observed in our galaxy's black hole. The astronomers used NASA´s Chandra X-Ray Observatory to detect the brightest flare ever observed from Sagittarius A*. The black hole is considered to be low-key, emitting very little energy for its size. It gives off about as much energy as the sun, despite it being 4 billion times as massive. The recent flare is...

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...

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...

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...

Top Physicists Come To Jerusalem To Mark 40 Years Since Jacob Bekenstein’s Famous Essay On The Entropy Of Black Holes
2012-09-04 09:53:43

Speakers include Nobel laureate and winner of new $3 million physics prize As the scientific community marks 40 years since the publication of Prof. Jacob Bekenstein's famous paper on black hole entropy, the Hebrew University of Jerusalem´s Institute for Advanced Studies is celebrating the occasion by hosting an international conference featuring the world´s top theoretical physicists. The Sep. 3-7 conference, Forty Years of Black Hole Thermodynamics, is presented in cooperation...

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...

Four Black Hole Candidates Discovered
2012-07-21 08:01:00

redOrbit Staff & Wire Reports - Your Universe Online Researchers from a Japanese university have discovered intermediate-mass black hole (IMBH) candidates at the center of the Milky Way, the National Astronomical Observatory of Japan (NAO) announced on Friday. Tomoharu Oka, an Associate Professor at Keio University, and colleagues used radio telescopes to locate four black hole candidates approximately 30,000 light-years from the solar system, located in the direction of the...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

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...

Cygnus X-1 -- Cygnus X-1 (often abbreviated to Cyg X-1) is an X-ray source in the Cygnus constellation considered to be one of the most likely black hole candidates. The optical counterpart (HDE 226868) is a variable 8.9 magnitude star (visible with good binoculars in good observing conditions.) at right ascension 19 h 56.5 min and declination of 35 deg 4 min (for 1950 epoch). Cyg X-1 is a binary star that contains a O9-B0 supergiant (with a surface temperature of 31000 Kelvin) and a...
