General relativity survives gruelling pulsar test
Astronomers have used a pair of pulsars orbiting each other, found with CSIRO's Parkes telescope in 2003, to show that Einstein's theory of general relativity is correct to within 0.05% - the most stringent limit to date. view more (2006-09-18)
First Image and Spectrum of a Dark Matter Object
Astronomers have observed a Dark Matter object directly for the first time. Images and spectra of a MACHO microlens - a nearby dwarf star that gravitationally focuses light from a star in another galaxy - were taken by the NASA/ESA Hubble Space Telescope and the European Southern Observatory's Very Large Telescope. The Riddle of Dark Matter The... view more... (2001-12-05)
ORNL mirrors powerful tools for studying micro-, nano-materials
Precision mirrors to focus X-rays and neutron beams could speed the path to new materials and perhaps help explain why computers, cell phones and satellites go on the blink. view more (2005-07-21)
Youngest solar systems detected by U-M astronomers
Astronomers at the University of Michigan have found what are believed to be some of the youngest solar systems yet detected. view more (2007-11-30)
University of Hawaii at Manoa astronomers discover pair of solar systems in the making
Two University of Hawai'i at Mānoa astronomers have found a binary star-disk system in which each star is surrounded by the kind of dust disk that is frequently the precursor of a planetary system. view more (2009-07-01)
A new radiation therapy treatment developed for head and neck cancer patients
Most head-and-neck cancers that recur locally after prior full-dose conventional radiation therapy respond to Boron Neutron Capture Therapy (BNCT). view more (2007-08-17)
Pinpoint accuracy with the Proba camera
A new star tracker allowing a satellite to determine its orientation in space with an accuracy never seen before has proved its worth aboard ESA`s Proba mission. Proba (Project for On-Board Autonomy) built by Verhaert (Belgium) for ESA was launched in Autumn 2001 and is now fully operational, carrying out a series of Earth observations with... view more...

Further UK bid to host European Spallation Source
A former airfield near a picturesque village in the north of England joined the bid to host the European Spallation Source (ESS) following an announcement today (14 May 2002) by the White Rose Consortium(1) - the universities of Leeds, Sheffield and York, and regional development agency Yorkshire Forward. Delegates at the European Spallation... view more... (2002-05-14)
Keck Study Sheds New Light on 'Dark' Gamma-ray Bursts
Gamma-ray bursts are the universe's biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. view more (2009-06-09)
Success For Early Double Star Launch
A rare event in the history of space exploration took place yesterday (25 July) when the second European-Chinese Double Star spacecraft lifted off a day early from Taiyuan spaceport, west of Beijing, on a Long March 2C rocket. The launch of the spacecraft, officially called Tan Ce 2 (Explorer 2), was brought forward one day to avoid bad weather.... view more... (2004-07-26)
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)
European Satellites Probe a New Magnetar
On Aug. 22, 2008, NASA's Swift satellite reported multiple blasts of radiation from a rare object known as a soft gamma repeater, or SGR. view more (2009-06-17)
Astronomers catch binary star explosion inside nebula
The explosion of a binary star inside a planetary nebula has been captured by a team led by UCL (University College London) researchers - an event that has not been witnessed for more than 100 years. view more (2008-11-20)
UK Astronomers look forward to looking back
When NASA launches its Space Infrared Telescope Facility (SIRTF) - the agency's fourth 'Great Observatory' - later this week, astronomers around the world will be looking forward to using one of the most powerful time machines ever built. Among those anticipating the opportunity to look back billions of years to an era when the universe was in its... view more... (2003-08-19)
NASA's Chandra sees brightest supernova ever
The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. view more (2007-05-08)
The Mouse That Roared: Pipsqueak Star Unleashes Monster Flare
On April 25, NASA's Swift satellite picked up the brightest flare ever seen from a normal star other than our Sun. The flare, an explosive release of energy from a star, packed the power of thousands of solar flares. It would have been visible to the naked eye if the star had been easily observable in the night sky at the time. view more (2008-05-20)
Largest, brightest supernova ever seen may be long-sought pair-instability supernova
An exploding star first observed last September is the largest and most luminous supernova ever seen, according to University of California, Berkeley, astronomers, and may be the first example of a type of massive exploding star rare today but probably common in the very early universe. view more (2007-05-08)
X-Rays Examine Colliding Galaxies
Galaxies were once thought of as `island universes` evolving slowly in complete isolation. This is now known not to be the case. By using the world`s most powerful X-ray observatories, UK astronomers are discovering that most of these gigantic star systems interact with each other in a wide variety of ways. During the UK National Astronomy Meeting... view more... (2002-04-07)
Discovery of Giant X-ray Loop Hints at Cosmic Particle Accelerator
Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 times the size of the Arches Cluster, a star-forming region close to the centre of the Milky Way. This is the first time that such a distinctive and... view more... (2005-03-31)
Interacting protein theory awaits test from new neutron analysis tools
An international collaboration directed by an Oak Ridge National Laboratory researcher has performed the first-ever atomic-detail computer simulation of how proteins vibrate in a crystal. view more (2007-09-28)
