  • Galaxy's Gamma-Ray Flares Erupted Far From Its Black Hole

    01.07.13 - In 2011, a months-long blast of energy launched by an enormous black hole almost 11 billion years ago swept past Earth. Using a combination of data from NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Very Long Baseline Array (VLBA), the world's largest radio telescope, astronomers have zeroed in on the source of this ancient outburst.

  • New Chandra Movie Features Neutron Star Action

    01.07.13 - Unlike with some blockbuster films, the sequel to a movie from NASA's Chandra X-ray Observatory is better than the first. This latest movie features a deeper look at a fast moving jet of particles produced by a rapidly rotating neutron star, and may provide new insight into the nature of some of the densest matter in the universe.

  • NASA Events Set for American Astronomical Society Meeting

    01.04.13 - NASA scientists will present new findings on a wide range of astrophysics topics next week at the annual meeting of the American Astronomical Society (AAS).

  • Researchers Identify Water Rich Meteorite Linked To Mars Crust

    01.03.13 - NASA-funded researchers analyzing a small meteorite that may be the first discovered from the Martian surface or crust have found it contains 10 times more water than other Martian meteorites from unknown origins.

  • NASA to Provide Dec. 17 Commentary as Twin Probes End Lunar Mission

    12.14.12 - NASA will provide live commentary of the scheduled lunar surface impacts of its twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft beginning at 2 p.m. PST (5 p.m. EST) Monday, Dec. 17.

  • NASA's Hubble Provides First Census of Galaxies Near Cosmic Dawn

    12.12.12 - Using NASA's Hubble Space Telescope, astronomers announced Dec. 12 they have seen further back in time than ever before and have uncovered a previously unseen population of seven primitive galaxies that formed more than 13 billion years ago, when the universe was less than 3 percent of its present age. The deepest images to date from Hubble yield the first statistically robust sample of galaxies that tells how abundant they were close to the era when galaxies first formed.

  • NASA Makes Unprecedented Return to Mars, Advances Commercial Spaceflight and Adds to its Amazing Research and Discoveries in 2012

    12.12.12 - In 2012, NASA continued to implement America's ambitious space exploration program, landing the most sophisticated rover on the surface of Mars, carrying out the first-ever commercial mission to the International Space Station and advancing the systems needed to send humans deeper into space.

  • NASA's Hubble to Reveal New Findings About the Early Universe

    12.10.12 - NASA will hold a media teleconference at 2 p.m. EST Wednesday, Dec. 12, to discuss the latest findings from NASA's Hubble Space Telescope. Astronomers will report on recent observations of a previously unseen population of primitive galaxies that formed more than 13 billion years ago.

  • NASA Astrobiology Institute Shows How Wide Binary Stars Form

    12.10.12 - Using computer simulations, scientists from the NASA Astrobiology Institute team at the University of Hawaii are shedding light on a question that has challenged astronomers for years: What causes wide binary stars?

  • Fermi Improves its Vision for Thunderstorm Gamma-Ray Flashes

    12.06.12 - Thanks to improved data analysis techniques and a new operating mode, the Gamma-ray Burst Monitor (GBM) aboard NASA's Fermi Gamma-ray Space Telescope is now 10 times better at catching the brief outbursts of high-energy light mysteriously produced above thunderstorms.
