Scientist: SETI success within 25 years?Santa Clara, Calif. (UPI) Aug 16, 2010 The search for extraterrestrial intelligence could yield proof of its existence within 25 years, a U.S. scientist involved in the quest says. Speaking at the SETI Con convention in Santa Clara, Calif., Seth Shostak - senior astronomer at the Search for Extraterrestrial Intelligence Institute in Mountain View, Calif. - said, "I actually think the chances that we'll find ET are pretty good," SPACE.COM reported Monday. "Young people in the audience, I think there's a really good chance yo ... read more |

Washington DC (SPX) Aug 13, 2010There are places in space where the gravitational tug between a planet and the Sun balance out, allowing other smaller bodies to remain stable. These places are called Lagrangian points. So-called Trojan asteroids have been found in some of these stable spots near Jupiter and Neptune. Trojans share their planet's orbit and help astronomers understand how the planets formed and how the sola ... more  
Pasadena CA (JPL) Aug 13, 2010Saturn's moon Titan ripples with mountains, and scientists have been trying to figure out how they form. The best explanation, it turns out, is that Titan is shrinking as it cools, wrinkling up the moon's surface like a raisin. A new model developed by scientists working with radar data obtained by NASA's Cassini spacecraft shows that differing densities in the outermost layers of Titan ca ... more  
Moffett Field CA (SPX) Aug 13, 2010A mysterious bias in the way the building blocks of proteins twist could be due to supernovae, researchers now suggest. If correct, this could be evidence that the molecules of life weren't created on Earth, but came from elsewhere in the cosmos. Organic molecules are often chiral, meaning they come in two versions that are mirror images of each other, much as right and left hands appear i ... more |

Giant Ultraviolet Rings Found In Resurrected GalaxiesPasadena CA (JPL) Aug 12, 2010 Astronomers have found mysterious, giant loops of ultraviolet light in aged, massive galaxies, which seem to have a second lease on life. Somehow these "over-the-hill galaxies" have been infused with fresh gas to form new stars that power these truly gargantuan rings, some of which could encircle several Milky Way galaxies. The discovery of these rings implies that bloated galaxies presumed "dead" and devoid of star-making can be reignited with star birth, and that galaxy evolution does not procee ... read more |
