Rapid star formation spotted in 'stellar nurseries' of infant galaxies
The Universe's infant galaxies enjoyed rapid growth spurts forming stars like our sun at a rate of up to 50 stars a year, according to scientists at Durham University. view more (2009-11-11)
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)
NASA's Fermi Telescope Detects Gamma-Ray From
Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. view more (2009-11-03)
Shedding light on the cosmic skeleton
"Matter is not distributed uniformly in the Universe," says Masayuki Tanaka from ESO, who led the new study. "In our cosmic vicinity, stars form in galaxies and galaxies usually form groups and clusters of galaxies. The most widely accepted cosmological theories predict that matter also clumps on a larger scale in the so-called... view more... (2009-11-03)

Particles as tracers for the most massive explosions in the Milky Way
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter". view more (2009-08-11)
Astronomers discover stars in early galaxies had a need for speed
A team of astronomers has measured the motions of stars in a very distant galaxy for the first time and discovered they are whizzing around at astonishingly high speeds-about one million miles per hour, or twice the speed at which the Sun circles our own Milky Way galaxy. view more (2009-08-07)
Cosmic dance helps galaxies lose weight
A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation. view more (2009-07-30)
Galaxy Zoo hunters help astronomers discover rare 'Green Pea' galaxies
A team of astronomers has discovered a group of rare galaxies called the "Green Peas" with the help of citizen scientists working through an online project called Galaxy Zoo. The finding could lend unique insights into how galaxies form stars in the early universe. view more (2009-07-28)
Herschel Space Telescope's SPIRE instrument package makes first-light observations
A scientific instrument package developed in part by the University of Colorado at Boulder for the $2.2 billion orbiting Herschel Space Observatory that was launched in May by the European Space Agency has made its first successful observations, targeting two star-forming galaxies near the Milky Way. view more (2009-07-13)
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)
Intense heat killed the Universe's would-be galaxies, researchers say
Our Milky Way galaxy only survived because it was already immersed in a large clump of dark matter which trapped gases inside it. view more (2009-07-01)
