The formation process involved two stages, said Mitchell Begelman, a professor and the chair of CU-Boulder's astrophysical and planetary sciences department. The predecessors to black hole format...
Physics and Astronomy |Not only is this the thinnest material possible, but it also is 10 times stronger than steel and it conducts electricity better than any other known material at room temperature. These and graphene...
Physics and Astronomy |In celebration of this International Year of Astronomy, NASA is releasing images of the galactic center region as seen by its Great Observatories to more than 150 planetariums, museums, nature centers...
Physics and Astronomy |"Intermediate-mass black holes contain between 100 and 10,000 times the sun's mass," explained Tod Strohmayer, an astrophysicist at Goddard. "We observe the heavyweight black holes...
Physics and Astronomy |"Starburst galaxies have not been accessible in gamma rays before," said Fermi team member Seth Digel, a physicist at SLAC National Accelerator Laboratory in Menlo Park, Calif. "Most of...
Physics and Astronomy |About half of 36 fish stocks in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the last four decades, with some stocks nearly disappearing ...
Ecology, The Environment and Conservation |Since the completion of the human genome sequence, a question has baffled researchers studying gene control: How is it that humans, being far more complex than the lowly yeast, do not proportionally c...
Life Sciences |The system works well, and millions rely on it every day, but what tells the GPS satellites where they are in the first place? "For GPS to work, the orbital position, or ephemeris, of the...
Information Technology |Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the ...
Physics and Astronomy |Dr Clive Trueman, who is based at the National Oceanography Centre, Southampton said:"Salmon farming is a big, intensive business. In 2006, around 130,000 tonnes of salmon were farmed in ...
Ecology, The Environment and Conservation |Life expectancy rose from 57.1 in 1929 to 63.3 years in 1932, according to the analysis by U-M researchers José A. Tapia Granados and Ana Diez Roux. The increase occurred for both men and women, and f...

Life Sciences |Permeating the region is a diffuse haze of X-ray light from gas that has been heated to millions of degrees by winds from massive young stars – which appear to form more frequently here than elsewhere...
Physics and Astronomy |This 34 by 20-degree wide image provides us with a view as experienced by amateur astronomers around the world. However, its incredible beauty and appeal owe much to the quality of the observing site ...
Physics and Astronomy |The flashes, known as gamma ray bursts, are beams of high energy radiation – similar to the radiation emitted by explosions of nuclear weapons – produced by jets of plasma from massive dying stars. ...
