Science with Integral -- 5 years on
With eyes that peer into the most energetic phenomena in the universe, ESA's Integral has been setting records, discovering the unexpected and helping understanding the unknown over its first five years. view more (2007-10-18)
High-energy particles from violent black holes travel to Earth
Ultra-high-energy particles from just outside enormous, active black holes in nearby galaxies travel as far as 250 million light years to make it all the way to Earth, an international team of 400 physicists and astronomers from 17 countries reports in the Nov. 9 issue of the journal Science. view more (2007-11-12)
New deep space images of distant strip of sky to be available on Google
A global project to map a distant strip of the universe is releasing its data today to scientists and the public to be used as part of Google Sky, a new feature of Google Earth. view more (2007-10-04)
RIT Study Confirms Supermassive Black Holes Produce Powerful Galaxy-Shaping Winds
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists from Rochester Institute of Technology. view more (2007-11-01)
NASA's Chandra Finds Evidence for Quasar Ignition
New data from NASA's Chandra X-ray Observatory may provide clues to how quasars "turn on." view more (2006-03-24)
Ghost Remains After Black Hole Eruption
NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole. view more (2009-05-29)
Sophisticated telescope camera debuts with peek at nest of black holes
Less than two months after they inaugurated the world's largest telescope, University of Florida astronomers have used one of the world's most advanced telescopic instruments to gather images of the heavens. view more (2009-09-16)
Astronomers find triple interactions of supermassive black holes to be common in early universe
New cosmological computer simulations produced by a team of astronomers from Northwestern University, Harvard University and the University of Michigan show for the first time that supermassive black holes (SMBHs), which exist at the centers of nearly all galaxies, often come together during triple galaxy interactions. view more (2007-01-09)
Grub's passion for plastic causes water loss
Research by the NSW Department of Primary Industries (DPI) has found that a small white grub is responsible for water leaking from sub-surface drip irrigation pipes used by some lucerne growers. view more (2007-09-27)
Perforating aircraft wings with minute holes could make for more efficient flying.
One way to make aeroplanes fly more efficiently is to drill millions of tiny holes in the leading edges of the wings. Like the dimples on a golf ball this has the effect of reducing drag. However, producing these holes on a manufacturing scale is not yet commercially feasible. Researchers at Heriot-Watt University, funded by the Engineering and... view more... (2002-01-14)
Does racial stereotyping still occur in psychiatry?
Ten years ago, psychiatrists rated black male patients as potentially more violent than white patients. A study in this week's BMJ asks does such racial stereotyping still occur? A postal questionnaire, concerning the first presentation of a young man at casualty, was sent to 1000 British psychiatrists. It included a photograph, brief history, and... view more... (2001-10-17)
The universe just became a little simpler
Using images from the Hubble Space Telescope, astronomers have concluded that two of the most common types of galaxies in the universe are in reality different versions of the same thing. In spite of their similar-sounding names, astronomers had long considered "dwarf elliptical" and "giant elliptical" galaxies... view more... (2003-06-18)
Dancing around the Black Hole
ISAAC Finds "Cool" Young Stellar Systems at the Centres of Active Galaxies Supermassive Black Holes are present at the centres of many galaxies, some weighing hundreds of millions times more than the Sun. These extremely dense objects cannot be observed directly, but violently moving gas clouds and stars in their strong gravitational fields are... view more... (2001-08-14)
Ethnicity important factor in rates of gonorrhoea and chlamydia infections
Rates of gonorrhoea and chlamydia are about three times as high in black Caribbeans as they are in black Africans, shows a study in Sexually Transmitted Infections. Cases of gonorrhoea and chlamydia, recorded at 11 sexual health clinics in Lambeth, Southwark, and Lewisham Health Authority for the years 1994 and 1995, were studied. Ethnic group was... view more... (2001-02-02)
Cluster Quartet Probes the Secrets of the Black Aurora
Swedish and British researchers have used the European Space Agency`s Cluster spacecraft to unveil the mysteries of the "black aurora", a strange electrical phenomenon that generates dark, empty regions adjacent to the visible Northern and Southern Lights. The new results, to be announced today at a meeting of the American Geophysical Union in San... view more... (2001-12-10)
Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies evolve in shape. view more (2008-07-30)
Hubble maps the changing constellation of Internet 'black holes'
You're trying to log on to a Web site and it's not working. You try again and again. But persistence doesn't pay off. The site you want is inexplicably, frustratingly, out of reach. view more (2008-04-09)
Universe's oldest objects emerge from the background
The deepest reaches of space are permeated by a cloak of infrared radiation, an uneven energy swath generated by long-dead objects from the early universe. view more (2006-12-20)
Black pudding may interfere with cancer screening test
Eating black pudding may interfere with a screening test for colorectal cancer, claim researchers in this week’s Christmas issue of the BMJ. view more (2002-12-18)
Black hole in search of a home
The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars. view more (2005-09-15)
