Gamma-Ray Image Reveals 'Some Things We Didn't Expect to See'
Last week astronomers released the most detailed gamma-ray map of the sky--representing the Universe's most violent and extreme processes. The Fermi space telescope's newest results, as well as the map, were described at the Third Fermi Symposium in Rome.
At the same meeting astronomers expressed bewilderment over an unprecedented blast of gamma rays, the highest-energy light in the Universe, coming from the Crab Nebula. They said the cause of the April 12 gamma-ray flare is a mystery.
Scientists have also been surprised by solar wind data collected by the Genesis Mission. The data show discrepancies between the composition of the sun and the inner solar system, which contains the sun's four closest planets, including Earth.
Finally, a new study bolsters the notion that the thick, nitrogen-rich atmosphere of Saturn's largest moon, Titan, was literally blasted into existence billions of years ago by comets or other objects pounding its icy surface.

VIDEO: The Promise and Peril of Drones
The automation of tasks at work and at home is just around the corner, including driving cars, piloting planes, delivering packages, and transporting weapons. Unmanned aerial vehicles are rapidly evolving to meet both society’s and the military’s needs in automation and better efficiency.
During her time as one of the first female fighter pilots in the US Navy, Dr. Missy Cummings observed that computers could take off and land a plane more precisely than humans. Because of this breakthrough and her fascination with this growing technology, she began human–drone interaction research.
