US-SPACE-ASTRONOMY
This NASA handout image obtained August 27, 2008 shows an all sky map. A new space telescope revealed the glowing gas of the Milky Way, pulsating stars and a flaring faraway galaxy as it began its mission to unveil the mysteries of cosmic gamma rays, NASA said.The US space agency released August 26, 2008 the first all-sky map created by the Fermi Gamma-ray Space Telescope, previously known as GLAST, with two high-tech instruments that scientists hope will help them uncover mysteries. The image was created with 95 hours of the instruments' first observations, displaying the probe's scientific potential. It took years for NASA's now-defunct Compton Gamma-ray Observatory to produce a similar map. Fermi's telescope scans the entire sky every three hours.Fermi's first all-sky image shows gas and dust in the plane of the milky way glowing in gamma rays as well as the Crab Nebula, Vela and Geminga pulsars shining brightly. The map also shows another bright spot shining about 7.1 billion light years away. "This is 3C 454.3 in Pegasus, a type of active galaxy called a blazar. It's now undergoing a flaring episode that makes it especially bright," NASA said. The telescope was renamed after American Nobel-winning physicist Enrico Fermi, a pioneer in high-energy physics.
