There could be one hundred billion Earth-like planets in our galaxy, a US conference has heard. Dr Alan Boss of the Carnegie Institution of Science said many of these worlds could be inhabited by simple life forms.

 Milky Way galaxy extraterrestrial life
Scientists will comb data sent back from Titan by the Huygens probe for the chemical signature of life in a bid to identify the moon's source of methane. Methane is constantly destroyed by UV light so there must be a source within Titan to replenish the atmosphere. Life is a possible - though some think unlikely - source of this hydrocarbon along with geological processes. The surface is too cold for biology, but microbes could...

The Jupiter Icy Moons Orbiter (Jimo) is part of an ambitious mission to explore the three planet-sized Jovian moons Callisto, Ganymede and Europa. Designing the spacecraft poses a significant engineering challenge given the long distances involved. Controversially, the probe is to be powered by a nuclear propulsion system. Callisto, Ganymede and Europa are thought to harbour oceans of probable water beneath an icy crust. Jimo would be the...

 Moon power extraterrestrial life nuclear Jupiter probe Callisto Ganymede Europa
Scientists have produced a global geological map of Jupiter's moon Europa, which has been proposed as a destination for a future space mission. Interest in Europa has been fuelled by indications that a liquid water ocean lurks beneath its outer shell of ice. The mapping effort will help build a geological history of the enigmatic moon and target future explorations...

 water ice Moon extraterrestrial life Jupiter Europa Galileo
Researchers are testing technology that could allow a lander to melt through the ice crust of Jupiter's moon Europa to reach the water ocean beneath. Space scientists want to send a craft to the Jovian moon because its ocean might, in theory, harbour life. Once through the 10-30km ice sheet, the probe could take a sample of water, to analyse it for microbial life...

Martian soil appears to contain sufficient nutrients to support life - or, at least, asparagus - Nasa scientists believe. Preliminary analysis by the $420m Phoenix Mars Lander mission on the planet's soil found it to be much more alkaline than expected. Scientists working on the spacecraft project said they were "flabbergasted" by the discovery. The find has raised hopes conditions on Mars may be favourable for life...

 Mars extraterrestrial life
The Pope's chief astronomer says that life on Mars cannot be ruled out. Writing in the Vatican newspaper, the astronomer, Father Gabriel Funes, said intelligent beings created by God could exist in outer space. ... Just as there are multiple forms of life on earth, so there could exist intelligent beings in outer space created by God. And some aliens could even be free from original sin, he speculates...
