Why SETI Counts
Sydney, Australia (SPX) Jun 04, 2012 - Are we alone in the universe? It's probably the greatest question posed by space exploration. It fascinates scientists and the general public. It's important and deeply compelling. We want to know, and we have ways of finding out. It doesn't cost much to operate a SETI (Search for Extraterrestrial Intelligence) program. Some space missions cost billions of dollars. Most cost hundreds of millions ...more

Dawn deep in the asteroid belt orbiting Vesta
Pasadena CA (JPL) Jun 04, 2012 - Far from Earth, on the opposite side of the sun, deep in the asteroid belt, Dawn is gradually spiraling around the giant protoplanet Vesta. Under the gentle pressure of its uniquely efficient ion propulsion system, the explorer is scaling the gravitational mountain from its low-altitude mapping orbit (LAMO) to its second high-altitude mapping orbit (HAMO2). Dawn spent nearly five months in ...more

There's more star-stuff out there but it's not Dark Matter
Canberra, Australia (SPX) Jun 04, 2012 - More atomic hydrogen gas - the ultimate fuel for stars - is lurking in today's Universe than we thought, CSIRO astronomer Dr Robert Braun has found. This is the first accurate measurement of this gas in galaxies close to our own. Just after the Big Bang the Universe's matter was almost entirely hydrogen atoms. Over time this gas of atoms came together and generated galaxies, stars and plan ...more

Catching solar particles infiltrating Earth's atmosphere
Greenbelt MD (SPX) Jun 04, 2012 - On May 17, 2012 an M-class flare exploded from the sun. The eruption also shot out a burst of solar particles traveling at nearly the speed of light that reached Earth about 20 minutes after the light from the flare. An M-class flare is considered a "moderate" flare, at least ten times less powerful than the largest X-class flares, but the particles sent out on May 17 were so fast and ener ...more

The 2012 Transit of Venus
Huntsville AL (SPX) Jun 04, 2012 - On June 5th, 2012, Venus will pass across the face of the sun, producing a silhouette that no one alive today will likely see again. Transits of Venus are very rare, coming in pairs separated by more than a hundred years. This June's transit, the bookend of a 2004-2012 pair, won't be repeated until the year 2117. Fortunately, the event is widely visible. Observers on seven continents, even a sli ...more

Venus, a Planetary Portrait of Inner Beauty
Pasadena CA (JPL) Jun 04, 2012 - A Venus transit across the face of the sun is a relatively rare event - occurring in pairs with more than a century separating each pair. There have been all of 53 transits of Venus across the sun between 2000 B.C. and the last one in 2004. On Wednesday, June 6 (Tuesday, June 5 from the Western Hemisphere), Earth gets another shot at it - and the last for a good long while. But beyond this uniqu ...more

Geoengineering could lead to a whiter sky
Washington DC (SPX) Jun 04, 2012 - One idea for fighting global warming is to increase the amount of aerosols in the atmosphere, scattering incoming solar energy away from the Earth's surface. But scientists theorize that this solar geoengineering could have a side effect of whitening the sky during the day. New research indicates that blocking 2 percent of the sun's light would make the sky three-to-five times brighter, as well ...more

James Cook and the Transit of Venus
Huntsville AL (SPX) Jun 04, 2012 - Every ~120 years a dark spot glides across the Sun. Small, inky-black, almost perfectly circular, it's no ordinary sunspot. Not everyone can see it, but some who do get the strangest feeling, of standing, toes curled in the damp sand, on the beach of a South Pacific isle.... City odors drifted in from Plymouth, across the ship, shoving aside the salt air. Sea gulls fluttered upward, screec ...more
