Liquid water and life on Mars and what drives the search for extraterrestrial life

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Data from NASA's Phoenix lander suggests that liquid water has interacted with the Martian surface throughout the planet's history and into modern times. The findings could have important implications in the search for signs of past or present life on the red planet. See article.
g Message - In the search for life on other worlds, scientists can listen for radio transmissions from stellar neighborhoods where intelligent civilizations might lurk or they can try to actually spot planets like our own in habitable zones around nearby stars. Either approach is tricky and relies on choosing the right targets for scrutiny out of the many thousands of nearby stars in our galactic neighborhood. See article. This article is from 2006.
g Learning - The NASA Astrobiology Roadmap and new discoveries are driving the search for extraterrestrial life, a group of scientists argue. See article.

Makes me think...of hybrid theories from modern abduction stories. Assuming that our genetics could link up...wouldn't hybridization be like a fast-track towards adaptation?

Hybridization between two species that evolved on two entirely differnet worlds seems unlikely given hybridization between two closely related species (like crossing a chimp and a gorilla) on Earth is virtually impossible. If aliens are visiting the Earth, they more than likely will have genetically re-engineered themselves for the flight through deep space.
