Biggest ever Gamma Ray search starts in Namibia
The world's most sensitive Gamma Ray telescopes are being inaugurated in Namibia (in Southwest Africa) on September 3rd. The High Energy Stereoscopic System (H.E.S.S.), a European/African collaboration in which the UK is a partner, will look for Gamma Rays produced by the most energetic particles... view more (2002-08-28)

NASA's Swift Sees Double Supernova in Galaxy
In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time.   view more (2007-06-27)

Starburst Galaxy Showers The Universe
When a galaxy known as M82 had a near-miss with its neighbour, it set off an explosive burst of star formation that sent plumes of hot gas tens of thousands of light years into space. Now a team of UK and American astronomers has discovered that these gas clouds are like the jets from a high... view more (2004-05-21)

'Beyond Einstein' research should begin with mission to study dark energy
NASA and the U.S. Department of Energy should pursue the Joint Dark Energy Mission (JDEM) as the first mission in the "Beyond Einstein" program, according to a new report from the National Research Council.   view more (2007-09-07)

Shrinking giants, exploding dwarves
When white dwarf stars explode, they leave behind a rapidly expanding cloud of 'stardust' known as a Type Ia supernova. These exploding events, which shine billions of times brighter than our sun, are all presumed to be extremely similar, and thus have been used extensively as cosmological... view more (2007-08-28)

Long-standing neutrino question resolved
An announcement by scientists at the Department of Energy's Fermilab today significantly clarifies the overall picture of how neutrinos behave.   view more (2007-04-12)

Super-computer reaches for the stars
Scientists at the University of York have been awarded a £234,000 grant for a powerful computer, called Beowulf, that will help them model large and fundamental happenings in the universe - from the evolution of the stars to the way in which DNA works. They will be using the grant from the... view more (2002-02-05)

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.... view more (2005-03-31)

Supernova Imposter Goes Supernova
In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006,... view more (2007-04-05)

A new unidentified very high energy gamma-ray source in our Galaxy
A European team based in Heidelberg (Germany) and their colleagues from the HEGRA collaboration have discovered a new, unidentified, very high energy gamma-ray source in our Galaxy. This source was detected via ground-based observations of the Imaging Atmosphere Cherenkov Telescope System.   view more (2004-12-14)

High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy... view more (2004-09-22)

Iowa State astrophysicists provide the eyes for new gamma ray telescope system
There's a "First Light Fiesta" in the works at Mt. Hopkins near Amado, Ariz. And Iowa State University astrophysicists will be among those enjoying the celebration of a new telescope system and all the science it will produce.   view more (2007-04-20)

Clues To Supernova Origin Found In Dusty Stellar Wind
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time... view more (2005-03-30)

A Strange Supernova with a Gamma-Ray Burst
On April 25, the BeppoSAX satellite detected a Gamma-Ray Burst from the direction of the constellation Telescopium, deep in the southern sky. Although there is now general consensus that they originate in very distant galaxies, the underlying physical causes of these events that release great... view more (1998-10-15)

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)

NASA: Major Step Toward Knowing Origin of Cosmic Rays
Recent observations from NASA and Japanese X-ray observatories have helped clarify one of the long-standing mysteries in astronomy -- the origin of cosmic rays.   view more (2007-10-10)

Gamma-ray bursts: are we safe?
For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as 'gamma-ray bursts' or GRBs. Astronomers using ESA's X-ray observatory, XMM-Newton, are trying to understand the cause of these... view more (2003-09-17)

Jekyll-Hyde neutron star discovered by researchers
Like something out of a Robert Louis Stevenson novel, researchers at NASA and McGill University discovered an otherwise normal pulsar which violently transformed itself temporarily into a magnetar, a stellar metamorphosis never observed before.   view more (2008-02-22)

Neutron stars can be more massive, while black holes are more rare, Arecibo Observatory finds
Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico.   view more (2008-01-15)

Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail.   view more (2007-04-25)

Astronomers Unravel Mystery of Gamma Ray Bursts
The cause of gamma ray bursts, the most violent and explosive events in the Universe, has remained a mystery since they were first discovered in 1967. Now a team of scientists, led by astronomers from the University of Leicester, believes they have found an answer to the puzzle. Their research... view more (2002-04-04)

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,... view more (2002-10-31)

White Dwarf Pulses Like a Pulsar
New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell... view more (2008-01-03)
