Astronomers in Chile and Japan have for the first time seen part of the "cosmic web" of galaxies that permeates the known universe in a gigantic assembly some seven billion light-years from Earth. Viewed through the world's most powerful telescopes, the discovery "is the first observation of such a prominent galaxy structure in the distant universe, providing further insight into the cosmic web and how it formed," the European Southern Observatory (ESO) said Tuesday in a statement. The assembly of galaxies form filaments "millions of light years long and constitute the skeleton of the universe," it said. "Galaxies gather around them, and immense galaxy ... Read Full Story

LOOK, UP IN THE SKY: The meteors will appear to come from Constellation Taurus. Map courtesy of Spaceweather.com Most people have heard of the annual Perseid meteor shower, which reaches its peak during a night-long period every August. But what about the Taurid meteor shower , which occurs when Earth passes through tiny debris shed by Comet 2p/Encke? Are you familiar with it? In many ways, the Taurids, which begins a week-long peak period tonight, is more interesting than the Perseids. As Spaceweather.com notes, “At most, only about 5 Taurids per hour streak across the sky, but what they lack in number they make ... Read Full Story
WASHINGTON (Reuters) - European astronomers announced they had found 32 new planets orbiting stars outside our solar system and said on Monday they believe their find means that 40 percent or more of Sun-like stars have such planets. The planets range in size from about five times the size of Earth to about five times the size of Jupiter, they said. More have been discovered, too, they said, promising more announcements later this year. The latest discoveries bring the total of known exoplanets to about 400, said Stephane Udry of the Geneva Observatory in Switzerland. "Nature doesn't like a vacuum so if there is ... Read Full Story

Jupiter snared a passing comet in the middle of the last century, eventually releasing it 12 years later, astronomers reported on Monday. Data presented at the European Planetary Science Congress in Potsdam, near Berlin, showed that the biggest planet of the Solar System gained a temporary satellite, a comet called 147P/Kushida-Muramatsu, between 1949 and 1961. It is only the fifth captured comet to be identified, a press release said. Comets are lonely wanderers of the Solar System, sometimes taking decades or even centuries to complete a long orbit around the Sun. On rare occasions, though, these enigmatic bodies of ice and dust can wander ... Read Full Story

“The exceptional sensitivity of these neural stem cells suggests that we are going to have to rethink our understanding of stem cell susceptibility to radiation, including cosmic radiation encountered during space travel, as well as radiation doses that accompany different medical procedures.” ~ Dennis A. Steindler, Ph.D., executive director of UF’s McKnight Brain Institute Imagine being stuck in a tin can for 3 years while all crew members increasingly lose their ability to adapt and control mood…not a pleasant picture. A new study has found that space radiation is something that will definitely have to be addressed before man can take long space flights. ... Read Full Story
