[08 December 2009]
- Every cook knows the ingredients for making bread: flour, water, yeast, and time. But what chemical elements are in the recipe of our universe?


Link to article COBE Satellite Marks 20th Anniversary
[19 November 2009]
- NASA's Cosmic Background Explorer (COBE) satellite rocketed into Earth orbit on Nov. 18, 1989, and quickly revolutionized our understanding of the early cosmos. Developed and built at Goddard Space Flight Center in Greenbelt, Md., COBE precisely measured and mapped the oldest light in the universe -- the cosmic microwave background.

[28 October 2009]
- During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. It captured more than one thousand discrete celestial sources which emit gamma rays -- the highest-energy form of light. Capping these achievements was a measurement that provided rare experimental evidence about the very structure of space and time.


Link to article First Black Holes Kept to a Strict Diet, Study Shows
[11 August 2009]
- A new supercomputer simulation designed to track the fate of the universe's first black holes finds that, counter to expectations, they couldn't efficiently gorge themselves on nearby gas. The findings have implications for understanding the formation of galaxies and of the giant black holes that reside in their centers.

[04 May 2009]
- NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen.


Link to article NASA'S Fermi Telescope Unveils a Dozen New Pulsars
[22 January 2009]
- NASA's Fermi Gamma-ray Space Telescope has discovered 12 new pulsars that emit only gamma rays. In addition, Fermi has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar cinders work.
