 Moffett Field CA (SPX) Aug 05, 2009 
With this essay by Ray Villard, news director for the Hubble Space Telescope, Astrobiology Magazine presents another in our series of 'Gedanken', or thought, experiments - musings by noted scientists on scientific mysteries in a series of "what if" scenarios. Gedanken experiments, which have been used for hundreds of years by scientists and philosophers to ponder thorny problems, rely on the pow ... read more 
Akron OH (SPX) Aug 05, 2009The National Aeronautics and Space Administration (NASA) and Goodyear Tire have developed an airless tire to transport large, long-range vehicles across the surface of the moon. The new "Spring Tire" with 800 load bearing springs is designed to carry much heavier vehicles over much greater distances than the wire mesh tire previously used on the Apollo Lunar Roving Vehicle (LRV). The new t ... more

Moffett Field CA (SPX) Aug 05, 2009Scientists have long debated the role of asteroid and comet impacts in mass extinctions on Earth. New research may indicate that it is highly unlikely that comets caused any mass extinctions. The findings could have implications in determining the likelihood of globally-damaging impacts in our planet's future. Scientists have debated how many mass extinction events in Earth's history were ... more 
Miami (UPI) Aug 3, 2009 Four Miami-area high school students have an unusual summer job on their resumes: building a cosmic ray detector alongside nuclear physicists. The four participated in a six-week paid internship with Florida International University's physics department, selected from a pool of top student applicants, The Miami Herald reported Monday. "It was a little overwhelming at first," Alys ... more 
Bangalore, India (IANS) Aug 04, 2009In the nine months India's Chandrayaan-1 has been circling the moon everyone connected with it has been awarded, rewarded or interviewed on TV, except the scientist whose pioneering work in liquid propulsion was pivotal to the mission's success. Perhaps it had something to do with the false spying charges under which he was arrested in 1994. It may seem odd but Nambi Narayanan who introduc ... more |

Moffett Field CA (SPX) Jul 30, 2009At the most recent NASA Astrobiology Science Conference, a panel of scientists discussed different types of planets where we might find alien life. In the fifth segment of this series, the panelists address questions from the audience about the search for life on Mars and elsewhere. Tori Hoehler: I think the question of manned exploration crystallizes around Mars. That's the one ... more 
Bonn, Germany (SPX) Jul 30, 2009An international team of astronomers, led by Keiichi Ohnaka at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, has taken the sharpest view of a dying mammoth star ever made. For the first time they could show, how the gas is moving in different areas over the surface of a distant star. This was made possible by combining three 1.8 m telescopes as an interferometer, giving the ... more  
Paris (AFP) July 29, 2009A day on Saturn is pretty short, and it just got shorter. The time it takes the beringed behemoth to complete a spin on its axis has just been calculated by astrophysicists at 10 hours, 34 minutes and 13 seconds, more than five minutes shorter than previous estimates. A planet comprising clouds of gas driven by layers of mighty jetstreams, Saturn has no lasting visual landmarks as a rock ... more |
