WASHINGTON, Oct. 19, 2011 /PRNewswire-USNewswire/ -- NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the "Late Heavy Bombardment," which may have brought water and other life-forming ingredients to Earth.

Using four of the world's largest telescopes, scientists have obtained the most detailed information yet from the regions around two young stars tens of light years away, finding compact discs of rocky and dusty material at distances comparable to that from the Earth to the Sun. Keele University astronomer Dr Rachel Smith will present the team's results on Wednesday April 14th at the RAS National Astronomy Meeting (NAM 2010) in Glasgow. The astronomers used data from the MIDI interferometer,...

Two terrestrial planets orbiting a mature sun-like star some 300 light-years from Earth recently suffered a violent collision, astronomers at UCLA, Tennessee State University and the California Institute of Technology will report in a December issue of the Astrophysical Journal, the premier journal of astronomy and astrophysics. "It's as if Earth and Venus collided with each other," said Benjamin Zuckerman, UCLA professor of physics and astronomy and a co-author on the paper. "Astronomers...

Enormous masses of dust floating around a binary star system suggest that two Earth-like planets demolished each other in a violent collision. "It's as if Earth and Venus collided with each other," said Benjamin Zuckerman, an astronomer at the University of California Los Angeles, who worked on the study. "Astronomers have never seen anything like this before; apparently major, catastrophic, collisions can take place in a fully mature planetary system." The team from UCLA, Tennessee State...

Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth. The extraordinary nature of the dust indicates a violent history of cosmic collisions between asteroids and comets, or perhaps even between planets. The discovery is published July 21 in Nature. "What is so amazing is that the amount of dust around this star is approximately 1 million times greater than the dust around the...

Gemini -- A relatively young star located about 300 light-years away is greatly improving our understanding of the formation of Earth-like planets. The star, going by the unassuming name of BD +20 307, is shrouded by the dustiest environment ever seen so close to a Sun-like star well after its formation. The warm dust is believed to be from recent collisions of rocky bodies at distances from the star comparable to that of the Earth from the Sun. The results were based on observations...
