    Cassini Spots Daytime Lightning on Saturn

    07.18.12 - 
    NASA’s Cassini spacecraft has captured images of last year’s storm on Saturn, the largest storm seen up-close at the planet, with bluish spots in the middle of swirling clouds. Those bluish spots indicate flashes of lightning and mark the first time scientists have detected lightning in visible wavelengths on the side of Saturn illuminated by the sun.

    Scientists know that the intensity of the lightning flash is comparable to the strongest flashes on Earth.

    Study Finds Heat is Source of ‘Pioneer Anomaly’

    07.18.12 - 
    The unexpected slowing of NASA’s Pioneer 10 and 11 spacecraft – the so-called “Pioneer Anomaly” – turns out to be due to the slight, but detectable effect of heat pushing back on the spacecraft, according to a recent paper.

    The results were published on June 12 in the journal Physical Review Letters.

    Harnessing Space Resources

    07.16.12 - 
    NASA researchers are in Hawaii this week analyzing effective ways to incorporate space resources into their spacecraft designs. The research helps improve spacecraft efficiency and guarantee the survival of hardware and people in space.

    This practice of harnessing resources at the exploration site is called in-situ-resource utilization (ISRU).

    Hubble Discovers a Fifth Moon Orbiting Pluto

    07.11.12 - 
    A team of astronomers using NASA’s Hubble Space Telescope discovered another moon orbiting the icy dwarf planet Pluto.

    The moon is estimated to be irregular in shape and 6-15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system.

    NASA/NOAA Satellite Sees Western U.S. Blazes

    07.13.12 - 
    Two of the most destructive fires in the history of Colorado and New Mexico have both now been contained.

    Together, the High Park Fire in Colorado and the Little Bear Fire in New Mexico have burned well over one hundred thousand acres and destroyed hundreds of homes and other buildings, displacing thousands of people and taking one life.

    Officials believe the blazes were caused by lightning strikes combined with dry hot summer conditions.

    July 12, 1962: The Day Information Went Global

    07.10.12 - 
    On July 12, 1962, the Telstar satellite relayed the world's first transatlantic television signal.

    Although operational for only a few months and relaying television signals of a brief duration, Telstar immediately captured the imagination of the world. The first images, those of President John F. Kennedy and of singer Yves Montand from France, along with clips of sporting events, images of the American flag waving in the breeze and a still image of Mount Rushmore.

    07.10.12 - 
    Astronomers have puzzled over why some puny, extremely faint dwarf galaxies spotted in our Milky Way galaxy's back yard contain so few stars.

    Hubble views of three of the small-fry galaxies reveal that their stars share the same birth date. The galaxies all started forming stars more than 13 billion years ago – and then abruptly stopped – all in the first billion years after the universe was born in the big bang.
