05.11.11 - The Stratospheric Observatory for Infrared Astronomy (SOFIA) program will showcase its science and education efforts to journalists on June 8 at NASA’s Dryden Aircraft Operations Facility in Palmdale, Calif.
05.11.11 - The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object. On April 12, NASA's Fermi Gamma-ray Space Telescope first detected the outburst, which lasted six days.
05.03.11 - NASA's Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.
04.28.11 - NASA will hold a news conference at 1 p.m. EDT on Wednesday, May 4, to discuss the science results and legacy of the Gravity Probe B (GP-B) mission.
04.28.11 - Late last year, astronomers noticed an asteroid named Scheila had unexpectedly brightened, and it was sporting short-lived plumes. Data from NASA's Swift satellite and Hubble Space Telescope showed these changes likely occurred after Scheila was struck by a much smaller asteroid.
04.21.11 - NASA will hold a special Science Update at 1 p.m. EDT on Thursday, April 28, to discuss the unprecedented journey of NASA's twin Voyager spacecraft to the edge of our solar system.
04.20.11 - To celebrate the 21st anniversary of the Hubble Space Telescope's deployment into space, astronomers at the Space Telescope Science Institute in Baltimore pointed Hubble's eye at an especially photogenic pair of interacting galaxies called Arp 273. The new image is available at: http://www.nasa.gov/hubble
04.12.11 - Astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, a mere 200 million years after the big bang.
03.31.11 - In a celestial forensic exercise, scientists analyzing data from NASA's Cassini, Galileo and New Horizons missions have traced telltale ripples in Saturn and Jupiter's rings to specific collisions with cometary fragments that occurred decades, not millions of years, ago.
03.25.11 - NASA's Stardust spacecraft sent its last transmission to Earth at 7:33 p.m. EDT Thursday, March 24, shortly after depleting fuel and ceasing operations.
