Orlando FL (SPX) Oct 11, 2010 Water ice on asteroids may be more common than expected, according to a new study that will be presented at the world's largest gathering of planetary scientists. Two teams of researchers who made national Water Discovered On Second Asteroid, May Be Even More Commons in April for showing the first evidence of water ice and organic molecules on an asteroid have now discovered that asteroid 65 Cybele contains the same material. "This discovery suggests that this region of our solar system contains more water ice than anticipated," said University of Central Florida Professor Humberto Campins. "And it supports the theory that asteroids may have hit Earth and brought our planet its water and the building blocks for life to form and evolve here." Asteroid 65 Cybele is somewhat larger than asteroid 24 Themis - the subject of the teams' first paper. Cybele has a diameter of 290 km (180 miles). Themis has a diameter of 200 km (124 miles). Both are in the same region of the asteroid belt between Mars and Jupiter. The academic article reporting this new finding has been accepted for publication in the European Journal "Astronomy and Astrophysics." Campins is an expert on asteroids and comets. He received national attention for an article published in Nature showing the first evidence of water ice and organic molecules on asteroid 24 Themis. He's also worked on several science missions with NASA and the European Space Agency. Campins holds degrees from the University of Kansas and the University of Arizona. He joined UCF in 2002 as the Provost Research Professor of Physics and Astronomy and head of the Planetary and Space Science Group.

Ground-Based Images Of Asteroid Lutetia Complement FlybyBoulder CO (SPX) Oct 11, 2010 On July 10, 2010, the European Space Agency (ESA) Rosetta spacecraft beamed back to Earth a dramatic set of close-up images as it flew past the 100-kilometer-sized asteroid (21) Lutetia, on its way to a comet rendezvous in 2014. But even before Rosetta made its close encounter with Lutetia, astronomers, using three of the world's largest telescopes, were busy making their own assessment of ... read more |
