Astrophysicists Solve Mystery in Milky Way Galaxy
A team of astrophysicists has solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the universe. view more (2009-07-09)
Peculiar, junior-sized supernova discovered by New York teen
In November 2008, Caroline Moore, a 14-year-old student from upstate New York, discovered a supernova in a nearby galaxy, making her the youngest person ever to do so. view more (2009-06-11)
Stellar explosion displays massive carbon footprint
While humans are still struggling to get rid of unwanted carbon it appears that the heavens are really rather good at it. view more (2009-06-01)
Rare radio supernova in nearby galaxy is nearest supernova in five years
The chance discovery last month of a rare radio supernova - an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes - underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. view more (2009-05-28)
Cosmology's Best Standard Candles Get Even Better
Members of the international Nearby Supernova Factory (SNfactory), a collaboration among the U.S. Department of Energy's Lawrence Berkeley National Laboratory, a consortium of French laboratories, and Yale University, have found a new technique that establishes the intrinsic brightness of Type Ia supernovae more accurately than ever before. view more (2009-05-19)
NC State Researchers
Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. view more (2009-04-23)
A Curious Pair of Galaxies
The ESO Very Large Telescope has taken the best image ever of a strange and chaotic duo of interwoven galaxies. The images also contain some surprises - interlopers both far and near. view more (2009-03-17)
Colors of Quasars Reveal a Dusty Universe
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II). view more (2009-02-26)
Cassiopeia A comes alive across time and space
Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant. view more (2009-01-06)
Earth not center of the universe, surrounded by 'dark energy': UBC cosmologists
