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 scientists say tests on a Mars rock show the planet could have supported primitive life. The analysis was done by the rover Curiosity, which drilled into the rock, crushed it and tested a tiny sample. The rover was the first spacecraft sent to Mars that could collect a sample from deep inside a rock.

In case you just can’t get enough impact news, it looks like Mars may actually get hit by a comet in 2014! As it stands right now, the chance of a direct impact are small, but it’s likely Mars will get pelted by the debris associated with the comet.

Millionaire spaceflier Dennis Tito has worked out a plan to send two astronauts to Mars and back without stopping — but the 501-day flight plan won’t work unless it launches in 2018.

The Mars rover Curiosity drilled into the Martian surface for the first time as part of an effort to learn if the planet most like Earth in the solar system ever had conditions to support microbial life, NASA said on Saturday.

Researchers find that 6% of red dwarf stars host habitable, Earth-sized planets - meaning the closest may be just 13 light-years away.

This sky map shows the location of Saturn and the moon in the night sky at 3 a.m. local time on Sunday, Jan. 6, 2013, for observers at mid-northern latitudes.

Astronomers trawling through a mess of stellar data discover that Tau Ceti, our nearest single Sun-like star, hosts five planets - one in its "habitable zone".

Science editor Alan Boyle's blog: Although NASA's Curiosity rover hasn't yet confirmed the detection of organic compounds on Mars, it's already seeing that the Red Planet's soil contains complex chemicals, including perchlorate.

Just in time for Christmas, scientists have confirmed a vast amount of ice at the north pole - on Mercury, the closest planet to the sun....
