Although more than 1,000 exoplanets have been discovered since the first one was found in 1995, only a handful of those are thought to be habitable, at least by life as we know it. New research shows that exomoons, too, could provide habitable environments. Although we are yet to find exomoons, we have good reasons to believe that there should be many, even more than exoplanets.

Astronomers believe the rough, icy surface of Jupiter's moon, Europa, is the most likely place in the solar system to harbour alien life.

Now Nasa has set aside £14.6 million ($25 million) to design probes that could reveal whether Europa is, in fact, habitable.

The agency yesterday asked scientists to come forward with potential experiments for a Europa probe that could be launched in the 2020s and arrive at the icy satellite within three years of take-off.

Jeremy England has come up with an interesting new hypothesis on the origins of life. In a sense, we exist to dissipate heat. Via BI:

From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat.

Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.

Researchers say they have potentially discovered the earliest signs of life on Earth in Western Australia's Pilbara, a breakthrough that may help scientists better understand the solar system.

The international team has found evidence of a complex microbial ecosystem in well-preserved sedimentary rocks that are almost three-and-a-half billion years old.
