NASA's Fermi Explores High-energy
Since its launch last June, NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars, probed gamma-ray bursts and watched flaring jets in galaxies billions of light-years away. view more (2009-05-05)
New theory sheds light on space enigma
An enormous plume of dust and water spurts violently into space from the south pole of Enceladus, Saturn's sixth-largest moon. This raging eruption has intrigued scientists ever since the Cassini spacecraft provided dramatic images of the phenomenon. view more (2008-02-25)
Asthma Research Breakthrough Holds Promise Of Cure
New research has made a vital breakthrough in the understanding of how asthma is caused, bringing the possibility of treatments for its prevention and cure. view more (1999-07-06)
U. of Colorado study shows desert droughts lead to earlier annual mountain snow loss
A new study spearheaded by the University of Colorado at Boulder's National Snow and Ice Data Center indicates wind-blown dust from drought-stricken and disturbed lands in the Southwest can shorten the duration of mountain snow cover hundreds of miles away in the Colorado mountains by roughly a month. view more (2007-06-26)
Massive-star supernovae found to be major space dust factories
An unaccounted for source of space dust which spawns life in the universe has been identified by an international team of scientists. view more (2006-06-09)
2007 hurricane forecasts took blow from winds and Saharan dry, dusty air
A new analysis of environmental conditions over the Atlantic Ocean shows that hot, dry air associated with dust outbreaks from the Sahara desert was a likely contributor to the quieter-than-expected 2007 hurricane season. view more (2008-08-19)
Cosmologists aim to observe first moments of universe
During the next decade, a delicate measurement of primordial light could reveal convincing evidence for the popular cosmic inflation theory, which proposes that a random, microscopic density fluctuation in the fabric of space and time gave birth to the universe in a hot big bang approximately 13.7 billion years ago. view more (2009-02-17)
Hidden Planet Pushes Star's Ring a Billion Miles Off-Center
A young star's strange elliptical ring of dust likely heralds the presence of an undiscovered Neptune-sized planet, says a University of Rochester astronomer in the latest Monthly Notices of the Royal Astronomical Society. view more (2007-06-14)
Killer algae a key player in mass extinctions
Supervolcanoes and cosmic impacts get all the terrible glory for causing mass extinctions, but a new theory suggests lowly algae may be the killer behind the world's great species annihilations. view more (2009-10-20)
Starburst galaxy sheds light on longstanding cosmic mystery
An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. view more (2009-11-03)
Allergens and viruses act together to worsen asthma
Common allergens (such as dust mite and grass pollen) and viruses may act together to exacerbate asthma, concludes a study in this week’s BMJ. view more (2002-03-27)
Integral looks at Earth to seek source of cosmic radiation
Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual method: observing Earth from space. view more (2006-03-17)

Possible cosmic defect may be a window into the early universe
An unusual cold spot in the oldest radiation in the universe, the cosmic microwave background, may be caused by a cosmic defect created just after the Big Bang, a Spanish and U.K. research team has found. view more (2007-10-26)
Superstrings could add gravitational cacophony to universe's chorus
Albert Einstein theorized long ago that moving matter would warp the fabric of four-dimensional space-time, sending out ripples of gravity called gravitational waves. No one has observed such a phenomenon so far, but University of Washington researchers believe it is possible to detect such waves coming from strange wispy structures called cosmic... view more...

Mystery of Quintuplet stars in Milky Way solved
For the first time, scientists have identified the cluster of Quintuplet stars in the Milky Way's galactic center, next to the super massive black hole, as massive binary stars nearing the end of their life cycle, solving a mystery that had dogged astronomers for more than 15 years. view more (2006-08-21)
U of M physicist reads the history of the solar system in grains of comet dust
Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin. view more (2008-01-04)
Turbulence May Promote the Birth of Massive Stars
On long, dark winter nights, the constellation of Orion the Hunter dominates the sky. Within the Hunter's sword, the Orion Nebula swaddles a cluster of newborn stars called the Trapezium. These stars are young but powerful, each one shining with the brilliance of 100,000 Suns. They are also massive, containing 15 to 30 times as much material as... view more... (2009-02-24)
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)
Examination of radiation left from birth of universe could alter theories
Using relic radiation from the birth of the universe, astrophysicists at the University of Illinois have proposed a new way of measuring the fine-structure constant in the past, and comparing it with today. view more (2007-04-03)
