 Moffett Field CA (SPX) Aug 20, 2009 
While far from a tropical rain forest, the equatorial region of Saturn's largest moon, Titan, has recently displayed tantalizing evidence that the parched, dry desert can support large-scale storms. The research, published in the journal Nature, announces the discovery of significant cloud formation (about three million square kilometers) within the moon's tropical zone near its equator. ... read more 
White Sands NM (SPX) Aug 20, 2009Anyone who's vacationed in the mountains or lived on a farm knows that it's hard to get good internet access or a strong cell phone signal in a remote area. Communicating across great distances has always been a challenge. So when NASA engineers designed the Lunar Reconnaissance Orbiter (LRO), they knew it would need an extraordinary communications system. Over the next year, the LRO, NASA ... more

Sydney, Australia (SPX) Aug 20, 2009For decades, microsatellites have been a boon to spaceflight. A small satellite can be built and launched fairly cheaply, sometimes hitching a ride for free aboard a large satellite launch. So far, microsatellites have not ventured very far into space. Could one go all the way to the Moon? Amateur groups have speculated on this possibility for years, but none have actually built a bird and ... more  
Pasadena CA (JPL) Aug 20, 2009How our solar system was formed has fascinated scientists and laymen alike for - well, for a really, really long time. New research may have answered a piece to the puzzle - how big were the first planetesimals? For those of you scoring at home," planetesimals" were the first solid objects in our newly minted solar system (also known as the protoplanetary disk). They began life as small ... more  
Pasadena CA (JPL) Aug 20, 2009For decades, astronomers have gone about their business of studying the cosmos with the assumption that stars of certain sizes form in certain quantities. Like grocery stores selling melons alone, and blueberries in bags of dozens or more, the universe was thought to create stars in specific bundles. In other words, the proportion of small to big stars was thought to be fixed. For every st ... more |

Sydney, Australia (SPX) Aug 17, 2009A team of scientists in Australia and the United States, led by Associate Professor Miroslav Filipovic from the University of Western Sydney, have discovered a new class of object which they call "Super Planetary Nebulae." They report their work in the journal Monthly Notices of the Royal Astronomical Society. Planetary nebulae are shells of gas and dust expelled by stars near the end of ... more  
Washington DC (SPX) Aug 18, 2009Will the universe expand outward for all of eternity and end in a vast, dark, cold, sterile, diffuse nothingness? Or will the "Big Bang" - the gargantuan explosion that formed the universe 14 billion years ago - end in the "Big Crunch?" Planets, stars and galaxies all hurtle inward and collapse into an incredibly hot, dense mass a billion times smaller than the period at the end of this ... more  
Greenbelt MD (SPX) Aug 18, 2009NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. "Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet," said Dr. Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. "Our discovery supports the ... more |
