NASA's Fermi Telescope Reveals Best-Ever View of Gamma-Ray Sky
A new map combining nearly three months of data from NASA's Fermi Gamma-ray Space Telescope is giving astronomers an unprecedented look at the high-energy cosmos. To Fermi's eyes, the universe is ablaze with gamma rays from sources ranging from within the solar system to galaxies billions of light-years away. view more (2009-03-12)
Galaxy cluster smashes distance record
The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes. view more (2009-10-23)
T-ray breakthrough could make detecting disease far easier
A breakthrough in the harnessing of 'T-rays'-electromagnetic terahertz waves-which could dramatically improve the detecting and sensing of objects as varied as biological cell abnormalities and explosives has been announced. view more (2006-11-03)
Hinode: new insights on the origin of solar wind
Spectacular images and data from the Hinode mission have shed new light on the Sun's magnetic field and the origins of solar wind, which can disrupt power grids, satellites and communications on Earth. view more (2007-12-10)
Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
Two brilliant flashes of light from nearby galaxies are puzzling astronomers and could indicate that gamma-ray bursts, which signal the birth of a black hole, are more diverse than once thought. view more (2006-12-21)
Scientists capture the speediest ever motion in a molecule
The fastest ever observations of protons moving within a molecule open a new window on fundamental processes in chemistry and biology, researchers report today in the journal Science. view more (2006-03-03)
The Last Cry Of Matter
'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be precise, astronomers do not detect black holes.... view more... (2003-11-27)
Researchers determine predicting factors of positive lung cancer diagnoses in chest radiographs
A study published in the June 2009 issue of the Journal of Thoracic Oncology determined several predictors of a positive lung cancer diagnosis after having an abnormal chest x-ray. view more (2009-06-02)
NASA's GLAST Satellite Gets Twin Solar Panels in Prep for Launch
Preparations for launching NASA's Gamma-ray Large Area Telescope (GLAST) satellite are underway at NASA's Kennedy Space Center (KSC), Fla. NASA KSC's "NASA Expendable Launch Vehicle Status Report" on Thursday, March 20, noted that GLAST's twin solar panels have been attached. view more (2008-04-02)
X-ray satellites discover the biggest collisions in the Universe
The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought. view more (2007-07-18)
Hinode reveals new insights about the origin of solar wind
Images from NASA-funded telescopes aboard a Japanese satellite have shed new light about the sun's magnetic field and the origins of solar wind, which disrupts power grids, satellites and communications on Earth. view more (2007-12-07)
A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts-both extremely luminous, distant objects-has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction of gamma-ray bursts than in the direction of quasars. view more (2006-08-01)
Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed. view more (2006-11-28)
NASA's Swift Catches Farthest Ever Gamma-Ray Burst
NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away. view more (2008-09-23)
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)
Distant 'Super-Starburst' Galaxies Hide Active Black Holes
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: view more (2005-03-31)
At the limits of the photoelectric effect
By way of the classical photoeffect, Einstein proved in 1905 that light also has particle character. However, with extremely high light intensities, remarkable things happen in the process. view more (2009-04-24)
`Quiet` star wasn`t quiet after all, say astronomers
For more than two years the star was `quiet`. Or so astronomers thought. But the X-ray pulsar EXO 2030+375 was abuzz with activity. Scientists simply lacked the ability to `hear` it over the hum of a nearby black hole. Now a study by scientists at the University of Southampton, the National Space Science and Technology Center (NSSTC) in... view more... (2002-07-10)
Cone-Beam CT faster, potentially more accurate than conventional mammography
Cone-beam breast CT provides exceptional tissue contrast and can potentially reduce examination time with comparable radiation dose to conventional 2D mammography, according to a new study by a team of researchers from the University of Texas M. D. Anderson Cancer Center in Houston. view more (2007-12-28)
Skylark Gets Set for Final Launch
The launch of the 441st Skylark sounding rocket marks the end of 50 years of outstanding scientific research that has included investigations into atmospheric conditions, X-ray astronomy, land use and the effects of microgravity. view more (2005-04-28)
