Mars, Jupiter | featured news

A British astrobiology conference has revived a years-old debate over the best place to look for life elsewhere in the solar system: Mars, or the moons of Jupiter and Saturn? "For reasons I don't really understand, the wider solar system and the potential for life there has not been high priority," The Telegraph quoted Robert Pappalardo, a senior research scientist at NASA's Jet Propulsion Laboratory, as saying on BBC Radio 4.

NASA's Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.

Jupiter and Mars aren't the only recent impact victims in our solar system. In two talks today at the Division for Planetary Sciences in Pasadena, California, astronomers report that a small asteroid located in the inner asteroid belt between those two planets took a major hit early last year.

Scientists have found lots of life-essential water – frozen as ice – in an unexpected place in our solar system: an asteroid between Mars and Jupiter.
