Using data from NASA's Fermi Gamma-ray Space Telescope, scientists have recently discovered a gigantic, mysterious structure in our galaxy. This feature looks like a pair of bubbles extending above and below our galaxy's center. Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old.
Launched in October 2006, STEREO traces the flow of energy and matter from the sun to Earth. It also provides unique and revolutionary views of the sun-Earth system. STEREO has given us the first view of the entire sun on February 6, 2011 and when coupled with SDO, will give us complete views of the sun's entire surface and atmosphere for the next 8 years.
Can't get enough of the recent launch of Discovery? Try looking at these unique (and mind-blowing) views: http://go.nasa.gov/h399W3 [video] – NASA (NASA) http://twitter.com/NASA/status/44861768031404032
"No time to look at the moon every night? Now you can just watch a time-lapse that shows a changing view of the moon over the course of 2011 (see video above). Created by a team at the Goddard Space Flight Center's Scientific Visualisation Studio, it's the first time a computer simulation has reproduced the shadows on the moon in such high resolution.
