Physicists Demonstrate How Information Can Escape From Black Holes (5/17/2008)

Physicists Demonstrate How Information Can Escape From Black HolesPhysicists have provided a mechanism by which information can be recovered from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Stephen Hawking. ...> Full Article


Searching the heavens (5/6/2008)

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. It could even help us comprehend the origin and distribution of dark matter ...> Full Article


Telescope helps give astronomers insights into blazars (4/24/2008)

For the first time, astronomers have observed a blazar in action, substantiating a prevailing theory about how these luminous and energetic galactic cores work. ...> Full Article

Giant Particle Accelerator Discovered In The Sky (1/28/2008)

Giant Particle Accelerator Discovered In The SkyESA's orbiting gamma-ray observatory, Integral, has made the first unambiguous discovery of highly energetic X-rays coming from a galaxy cluster. The find has shown the cluster to be a giant particle accelerator. ...> Full Article


Integral discovers the galaxy's antimatter cloud is lopsided (1/13/2008)

Integral discovers the galaxy's antimatter cloud is lopsidedThe shape of the mysterious cloud of antimatter in the central regions of the Milky Way has been revealed by ESA's orbiting gamma-ray observatory Integral. The unexpectedly lopsided shape is a new clue to the origin of the antimatter. ...> Full Article


Lack Of Gravitational Wave Prompts Fresh Look At Gamma Ray Burst (1/5/2008)

Lack Of Gravitational Wave Prompts Fresh Look At Gamma Ray BurstAn international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from merging neutron stars or black holes within Andromeda. ...> Full Article


Mysterious Cosmic Powerhouses Explored (12/27/2007)

Mysterious Cosmic Powerhouses ExploredBy working in synergy with a ground-based telescope array, the joint Japanese Aerospace Exploration Agency (JAXA)/NASA Suzaku X-ray observatory is shedding new light on some of the most energetic objects in our galaxy, but objects that remain shrouded in mystery. ...> Full Article


Intergalactic cosmic explosion shocks astronomers (12/25/2007)

Intergalactic cosmic explosion shocks astronomersA team of astronomers at Penn State and Caltech has discovered a cosmic explosion that seems to have come from the middle of nowhere -- thousands of light-years from the nearest galaxy-sized collection of stars, gas and dust. This "shot in the dark" is surprising because the type of explosion, a long-duration gamma-ray burst (GRB), is thought to be powered by the death of a massive star. ...> Full Article


Gamma Ray Delay May Be Sign of 'New Physics' (10/1/2007)

Gamma Ray Delay May Be Sign of 'New Physics'Delayed gamma rays from deep space may provide the first evidence for physics beyond current theories. ...> Full Article


Mysterious Energy Burst Stuns Astronomers (9/30/2007)

Mysterious Energy Burst Stuns AstronomersIn a shock finding, astronomers using CSIRO's Parkes telescope have detected a huge burst of radio energy from the distant universe that could open up a new field in astrophysics. ...> Full Article


Astrophysicists predict most dangerous explosions (9/11/2007)

Astrophysicists predict most dangerous explosionsA team of astrophysicists at The University of Western Australia today announced results from a new computer program that predicts when potentially dangerous bursts of gamma radiation may hit our planet. ...> Full Article
