Researchers have proposed a new project for analyzing Martian soil samples -- the "Search for Extraterrestrial Genomes" based on the theory that life on Mars – if there is any – may be composed of "island species" that were carried away from Earth on interplanetary meteorites.

As the citizens of Planet Earth strive ever more enthusiastically to reach E.T., some experts say numerous messages zipping through the cosmos are confusing or little more than space spam. Others ask who has the right to represent our world to the galaxy -- or question the wisdom of bellowing out our presence in what may be a hostile neighbourhood.

The chances of earth being detected by alien life forms are disappearing because the digital revolution has decreased analogue transmissions from television, radio and radar, a leading space scientist has claimed.

The authors present their new findings that the multiple "pocket universes" in the mutiverse predicted by prevailing theories in cosmology may not be inhospitable to life as previously thought and could contain life as well.

The search for dark energy might help in the search for life in the universe. That's because planet hunting through a technique called microlensing requires a similar sort of instrument as a dark energy mission.

A statistical method, from the branch of mathematics called information theory, that picks out the most significant words in a book could help scholars decode ancient texts like the Voynich manuscript - or even messages from aliens.

Using the gravitational microlensing technique, a new study claims to have have detected a planet near Andromeda, our nearest large galactic neighbour.

Scientists have devised a way to spot water on distant planets that can only barely be seen now, which in turn could reveal whether they might be able to support life.

New research shows how the coming generation of space telescopes will for the first time be capable of detecting "biosignatures" in the light from planets orbiting other stars.
