Time-lapse snapshots of a nova's fading light
Scientists in a collaboration led by Dai Takei of the RIKEN SPring-8 Center in Japan have, for the first time, examined a detailed 'time lapse' X-ray image of the expansion of a classical nova explosion using the GK Persei nova -- a binary star system which underwent a nova explosion in 1901. View News Article (2015-03-18)


IceCube neutrino observatory nears complete
In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, whiuch is located beneath the Antarctic ice -- will finally be completed after two decades of planning. View News Article (2010-09-01)


Astronomers find puzzling dwarf star with complex magnetic fields
Typically, little M-dwarf stars-the most common type of star in the galaxy-are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform. View News Article (2007-12-06)


Cosmic accelerators discovered in our galaxy by UCLA physicists, Japanese colleague
Physicists from UCLA and Japan have discovered evidence of "natural nuclear accelerators" at work in our Milky Way galaxy, based on an analysis of data from the world's largest cosmic ray detector. View News Article (2010-08-18)


Diagnosis murder
Black holes have long been beloved of science fiction writers for their destructive capabilities and peculiar ability to warp space time. Now a study led by researchers from The University of Nottingham reveals the awesome power of supermassive black holes -- the ability to strip massive galaxies of the cool gases required to form new stars, leaving ageing red giants to splutter out of existence...

CERN scientists predict supernova
A team of theoretical physicists working at CERN and the Technion Institute of Technology in Israel has developed a theory to account for the mysterious gamma ray bursts that come from the depths of the Universe. According to their ideas, gamma ray bursts are linked to supernovae, the cataclysmic explosions of massive stars at the end of their lives. When a new gamma ray burst (GRB 030329) was...

Clouds seen circling supermassive black holes
Astronomers see huge clouds of gas orbiting supermassive black holes at the centers of galaxies. Once thought to be a relatively uniform, fog-like ring, the accreting matter instead forms clumps dense enough to intermittently dim the intense radiation blazing forth as these enormous objects condense and consume matter. View News Article (2014-02-20)


A Vanishing Star Revisited
Reinhold H'¬§fner of the Munich University Observatory (Germany) is a happy astronomer. View News Article (1999-07-20)


Gamma-ray birth cries suggest massive magnetic engines
Several times a week, astronomers detect the violent death cry of a massive star — an extraordinarily energetic release of gamma rays that takes place in just a matter of seconds to minutes, called a gamma-ray burst (GRB). View News Article (2007-03-09)


Black holes, galaxies young and old visible in massive mapping of the night sky
Color images documenting the past 10 billion years of galactic evolution were distributed online this week as part of the first public release of data from a massive project to map a distant region of the universe that combines the efforts of nearly 100 researchers from around the world, including the University of Pittsburgh. View News Article (2007-10-04)
