Milky Way's Giant Black Hole Awoke from Slumber 300 Years Ago
Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy's central black hole let loose a powerful flare three centuries ago. view more (2008-04-16)
Searching the heavens
A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. view more (2008-05-01)
Old pulsars still have new tricks to teach us
The super-sensitivity of ESA's XMM-Newton X-ray observatory has shown that the prevailing theory of how stellar corpses, known as pulsars, generate their X-rays needs revising. view more (2006-07-26)
Knobbly kneed ID
Forget LED thumb-pad identification devices, complex retinal laser scanning, or even computerized iris recognition, the way forward for biometric validation is a quick X-ray snapshot of a person's knees, according to a report published in the International Journal of Biometrics. view more (2009-03-26)
X-ray Science gets a further £3.4M
A world-leading UK research project to study the properties of new materials has been given further funding of £3.4M. The grant is for the continued operation of the British funded X-ray Beamline ( XMaS - X-ray Magnetic Scattering) based at the European Synchrotron Radiation Facility at Grenoble, France. In very basic terms the synchrotron... view more... (2002-05-28)
Supernova birth seen for first time
Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time. view more (2008-05-22)
NASA's Swift, Fermi Probe Fireworks From a Flaring Gamma-Ray Star
Astronomers using NASA's Swift satellite and Fermi Gamma-ray Space Telescope are seeing frequent blasts from a stellar remnant 30,000 light-years away. view more (2009-02-11)
X-Ray For Grain
Researchers from St. Petersburg have invented a way to check the viability of grains and seeds of agricultural plants without prior germination. The scientists assume that injuries of the germ and tissues of seeds can be revealed through X-ray photomicrography with the help of computer recognition system. This methodology allows determining the... view more... (2003-02-20)
Gamma-ray photon race ends in dead heat; Einstein wins this round
Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. view more (2009-10-29)
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)
Chandra examines Jupiter during new horizons approach
On February 28, 2007, NASA's New Horizons spacecraft made its closest approach to Jupiter on its ultimate journey to Pluto. This flyby gave scientists a unique opportunity to study Jupiter using the package of instruments available on New Horizons, while coordinating observations from both space- and ground-based telescopes including NASA's... view more...

Improving our ability to peek inside molecules
It's not easy to see a single molecule inside a living cell. Nevertheless, researchers at Lawrence Livermore National Laboratory are helping to develop a new technique that will enable them to create detailed high-resolution images, giving scientists an unprecedented look at the atomic structure of cellular molecules. view more (2008-09-17)
Brightest stellar explosion heralds new type of long-distance astronomy
A flash of light that blinded even small telescopes six months ago was the brightest astronomical explosion ever observed - visible to the naked eye despite originating halfway across the universe. view more (2008-09-11)
New Method for Measuring Residual Stress Developed at Oxford
An inventor in Oxford University’s Department of Engineering Science has developed a new portable instrument for the measurement of residual stress in engineering components and structures. view more (2002-11-13)
SMART-1 detects calcium on the Moon
Thanks to measurements by the D-CIXS X-ray spectrometer, ESA's SMART-1 spacecraft has made the first ever unambiguous remote-sensing detection of calcium on the Moon. view more (2005-06-08)
Record: fastest flashing star
Dutch researcher Steve van Straaten set a record during his doctoral research. The researcher registered the fastest ever change in the X-ray emission originating from a binary star. The record-breaking binary star consists of a neutron star and a lighter companion star. Astronomer Steve van Straaten studied the time variations in the X-ray... view more... (2004-05-07)
T-rays: New imaging technology spotlighted by American Chemical Society
T-ray sensing and imaging technology, which can spot cracks in space shuttle foam, see biological agents through a sealed envelope and detect tumors without harmful radiation, was the focus of a recent symposium at the national meeting of the American Chemical Society. view more (2005-12-07)
MAGIC discovers variable very high energy gamma-ray emission from a microquasar
In a recent issue of Science Magazine, the Major Atmospheric Gamma-ray ImagingCherenkov (MAGIC) Telescope has reported the discovery of variable very high energy (VHE) gamma-ray emission from a microquasar. view more (2006-05-19)
Immune system pathway identified to fight allergens, asthma
For the first time, researchers from the University of Pittsburgh School of Medicine have identified genetic components of dendritic cells that are key to asthma and allergy-related immune response malfunction. view more (2008-05-08)
NASA celebrates Chandra X-Ray Observatory's 10th anniversary
Ten years ago, on July 23, 1999, NASA's Chandra X-ray Observatory was launched aboard the space shuttle Columbia and deployed into orbit. view more (2009-07-24)
