Odds For Life Better In Photosynthesis ZonesMoffett Field CA (SPX) Jul 26, 2010 By calculating where photosynthesis might be possible around the galaxy, scientists are developing a new way to figure out where Earth-like planets with life might be located. When seeking to figure out where life might evolve, researchers have often focused on the "habitable zones" around stars, where the heat from the star is at the perfect level for liquid water to exist on the surface of a planet in that zone. The reasoning there is that wherever there is water on Earth, there is a chance for ... read more |

Antarctica Traced From Space
Washington DC (SPX) Jul 26, 2010Antarctica may not be the world's largest landmass - it's the fifth-largest continent - but resting on top of that land is the world's largest ice sheet. That ice holds more than 60 percent of Earth's fresh water and carries the potential to significantly raise sea level. The continent is losing ice to the sea, and scientists want to know how much. Antarctica's ice generally flows from the ... more e2v Delivers Over 150 Imaging Sensors For ESA's Galaxy Mapping Mission Gaia
Essex, UK (SPX) Jul 26, 2010e2v, a leading designer, developer and manufacturer of high performance imaging sensors has delivered over 150 Charge Coupled Devices (CCD) imaging sensors for Gaia, a European Space Agency (ESA) cornerstone mission. Due to launch in 2012, Gaia's goal is to map the positions, parallaxes and proper motions (movement across the sky) of around 1 billion objects in our galaxy, the Milky Way, t ... more Hyperfast Star Was Booted From Milky Way
Boston MA (SPX) Jul 23, 2010A hundred million years ago, a triple-star system was traveling through the bustling center of our Milky Way galaxy when it made a life-changing misstep. The trio wandered too close to the galaxy's giant black hole, which captured one of the stars and hurled the other two out of the Milky Way. Adding to the stellar game of musical chairs, the two outbound stars merged to form a super- hot, blue ... more |

Elusive Buckyballs Found In Space For First TimePasadena CA (SPX) Jul 23, 2010 Astronomers using NASA's Spitzer Space Telescope have discovered carbon molecules, known as "buckyballs," in space for the first time. Buckyballs are soccer-ball-shaped molecules that were first observed in a laboratory 25 years ago. They are named for their resemblance to architect Buckminster Fuller's geodesic domes, which have interlocking circles on the surface of a partial sphere. Buckyballs were thought to float around in space, but had escaped detection until now. "We found what are n ... read more |
