Eurekalert.org Monday, November 02, 2009Scientists Detect Most Distance Object Ever SeenOnly 630 million years after the creation of the Universe a super-massive star exploded in a violent supernova. The energy from this explosion has been traveling across the Universe ever since, more than 13 billion years. This event marks the most distance object ever observed. These types of events, known as a gamma-ray burst or GRB, typically occur at least twice a week on average. However, this is the oldest event ever recorded, besting the previous mark by 150 million years. GRBs are important to understanding the Universe as they allow us to "see" events that occured billions of years ago. Normally, celestial events are difficult to observe when they are that far away, but GRBs emit so much light, particularly in the gamma-ray band (hence the name), that scientists can easily detect them.

About Monday, November 02, 2009'Ultra-primitive' particles found in comet dust(Carnegie Institution) Dust samples collected from the stratosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. The dust includes presolar grains and material from interstellar molecular clouds. This "ultra-primitive" material likely wafted into the atmosphere after the Earth passed through the trail of an Earth-crossing comet in 2003, giving scientists a rare opportunity to study cometary dust in the laboratory.
Eurekalert.org Monday, November 02, 2009High-precision measurements confirm cosmologists' standard view of the universe(DOE/SLAC National Accelerator Laboratory) A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by Sarah Church of KIPAC, jointly located SLAC and Stanford University, and by Walter Gear, of Cardiff University. These measurements put limits on proposed alternatives to the standard model of cosmology and provide further support for the standard cosmological model, confirming that dark matter and dark energy make up 95 percent of everything in existence.
Eurekalert.org Monday, November 02, 2009Starburst galaxy sheds light on longstanding cosmic mystery(University of Delaware) 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. The gamma rays observed by the team are the highest-energy photons ever detected from a galaxy undergoing large amounts of star formation and point to the origins of cosmic rays.
