How Martian geology may have affected life and Communication with Extraterrestrial Intelligence

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 - Some of the features on Mars that have been interpreted as large, ancient riverbeds might actually be evidence of massive, fast-moving, low-viscosity lava flows. The new study could have implications in the search for signs of past life on Mars. See article.
g Message - SETI (Search for Extraterrestrial Intelligence) is a scientific area whose goal is to detect intelligent life outside Earth. One approach, known as radio SETI, uses radio telescopes to listen for narrow-bandwidth radio signals from space. Such signals are not known to occur naturally, so a detection would provide evidence of extraterrestrial technology. See article.
g Aftermath - In the last quarter of the 20th century, an international social movement — Communication with Extraterrestrial Intelligence — has emerged which advocates an attempt to achieve communication with extraterrestrial intelligence, and many of its most active members have been leading scientists. Modest efforts to detect radio signals from intelligent extraterrestrials already have been made, both under government aegis and privately funded, and the technical means for a more vigorous search have been developed. If a CETI project were successful, linguists would suddenly have one or more utterly alien languages to study, and some consideration of linguistic issues is a necessary preparation for it.
