    HuScience Nugget: Lightning Signature Could Help Reveal the Solar System's Originsbble Sees the Eye of the Storm in Galaxy Cluster

    May 4, 2012

    As lightning flashes, it creates low frequency waves that circle Earth, a phenomenon known as Schumann Resonance, which tells scientists what kinds of atoms exist in a planet's atmosphere.

    Cassini to Probe Enceladus Gravity, Take Pictures

    May 2, 2012

    NASA's Cassini spacecraft will be flying within about 46 miles (74 kilometers) of Saturn's moon Enceladus on Wednesday, May 2, aiming primarily to learn more about the moon's internal structure. The flyby is the third part of a trilogy of flybys -- the other two took place on April 28, 2010, and Nov. 30, 2010 -- for Cassini's radio science experiment.

    100 Days and Counting to NASA's Curiosity Mars Rover Landing 04.27.12

    April 30, 2012

    At 10:31 p.m. PDT today, April 27, (1:31 p.m. EDT), NASA's Mars Science Laboratory, carrying the one-ton Curiosity rover, will be within 100 days from its appointment with the Martian surface. At that moment, the mission has about 119 million miles (191 million kilometers) to go and is closing at a speed of 13,000 mph (21,000 kilometers per hour).

    Fireball Over California/Nevada

    April 25, 2012

    A bright ball of light traveling east to west was seen over the skies of central/northern California Sunday morning, April 22. The former space rock-turned-flaming-meteor entered Earth's atmosphere around 8 a.m. PDT. Reports of the fireball have come in from as far north as Sacramento, Calif. and as far east as North Las Vegas, Nev.

    Study Finds Surprising Arctic Methane Emission Source

    April 23, 2012

    A new airborne study with NASA contributions measured surprising levels of the potent greenhouse gas methane coming from cracks in Arctic sea ice and areas of partial sea ice cover. This image was taken over the Arctic Ocean at a latitude of approximately 71 degrees North on April 15, 2010.

    Year Two: SDO Highlights On Its Anniversary

    April 23, 2012

    In April of 2010, NASA's Solar Dynamics Observatory (SDO) released its first images, an event known for any telescope as "first light." Since then SDO has continually observed the ever-changing sun on quiet days and explosive ones: there have been more than 1000 solar outbursts since SDO sent back its first pictures of the sun, including flares, coronal mass ejections (CMEs), and the release of energetic particles that can be flung to the farthest reaches of the solar system. Here we describe some of the highlights of SDO science and observations during its second year.

    Discovery Departs Kennedy Space Center

    April 18, 2012

    Space shuttle Discovery departed NASA's Kennedy Space Center in Florida for the last time with an early-morning takeoff atop NASA's Shuttle Carrier Aircraft (SCA). Instead of blazing a trail toward low Earth orbit, the agency's most-flown shuttle is on its way to Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center in Chantilly, Va.
