HRH The Prince of Wales to visit Jodrell Bank Observatory
HRH The Prince of Wales will visit The University of Manchester's Jodrell Bank Observatory in Cheshire on Monday, 28 April 2003, to commemorate the re-birth of its flagship Lovell Telescope following a major upgrade. The £2.5 million three-year upgrade saw the replacement of the 76-metre radio telescope's reflecting surface, which is now in... view more... (2003-04-25)
NASA's Chandra finds black holes are 'green'

Research suggests social factors behind higher schizophrenia rate in British African-Caribbeans
Unemployment and earlier separation from both parents may be key factors behind the higher rates of schizophrenia in British African-Caribbeans, according to new research by a scientist at The Centre for Caribbean Medicine, King's College London. view more (2002-06-19)
Scientists weigh ingredients in recipe of the Universe
An international team of scientists from Cambridge, Manchester and Tenerife has released the first results of new high-precision observations of the relic radiation from the Big Bang, often called the cosmic microwave background or CMB. These observations have been made with a novel radio telescope called the Very Small Array (VSA) situated on... view more... (2002-05-23)
Dark Energy From the Ground Up: Make Way for BigBOSS
Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, "supernovae" for short, certainly works: it's how dark energy was discovered in the first place. Other independent techniques, such as weak gravitational lensing and baryon acoustic oscillation, also promise great power but are... view more... (2009-08-07)
Surfing a Black Hole
An international team of astronomers [2], lead by researchers at the Max-Planck Institute for Extraterrestrial Physics (MPE), has directly observed an otherwise normal star orbiting the supermassive black hole at the center of the Milky Way Galaxy. Ten years of painstaking measurements have been crowned by a series of unique images obtained by the... view more... (2002-10-14)
New population of faint protogalaxies discovered
Astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15% of its present age. view more (2007-11-29)
Cosmic dust in farthest quasar clue to early star formation
UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is at a redshift (z) of 6.43, and is found in the direction of the constellation of Ursa Major. It is some 13 billion light years away, and we are... view more...

Galaxies gone wild!
Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies. view more (2008-04-24)
Vanderbilt astronomers participate in new search for dark energy
The most ambitious attempt yet to trace the history of the universe has seen "first light." The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey III (SDSS-III), took its first astronomical data on the night of Sept. 14-15 at the Sloan Foundation telescope in New Mexico. view more (2009-10-02)
Polarizing filter allows astronomers to see disks surrounding black holes
For the first time, a team of international researchers has found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be. view more (2008-07-24)
Radio Telescopes Reveal Unseen Galactic Cannibalism
Radio-telescope images have revealed previously-unseen galactic cannibalism -- a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies. Astronomers have long suspected that the extra-bright cores of spiral galaxies called Seyfert galaxies are powered by supermassive black holes consuming material.... view more... (2008-06-24)
First detection of magnetic field in distant galaxy produces a surprise
Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago. view more (2008-10-02)
Bringing astronomy into sharper focus
Scientists from the University of Cambridge's Astrophysics Group have today (21 June 2002) announced a collaboration with teams based in New Mexico, Puerto Rico and at the Naval Research Laboratory in Washington DC to design, install and operate a novel type of astronomical telescope for ultra-high angular resolution observations of stars,... view more...

Discovery of the chemically oldest star in the Milky Way
During the last 30 years researchers have tried to find stars that still carry vestiges of the very origin of the Milky Way Galaxy, when it formed from a gigantic collection of gas soon after the Big Bang. The gas of our galaxy, which was presumably composed of hydrogen and helium at the beginning, is continuously polluted by exploding stars that... view more... (2002-10-31)
Milagro detects cosmic ray hot spots
The University of Maryland-led Milagro collaboration, comprised of scientists from 16 institutions across the United States, has discovered two nearby regions with an unexpected excess of cosmic rays. view more (2008-11-25)
Variable physical laws
Physical quantities such as the speed of light, the gravitational constant and the electron mass are believed to be the same independent of where and when they appear in the universe. view more (2006-06-12)
