3D images of Mars’ polar ice layers and what it’s like to listen for aliens signals for a living

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Certain stars stream vast amounts of matter into space, creating some of the most beautiful objects in astronomers' telescopes. But while the astronomers can enjoy the beauty, they can't explain it. See article.
g Abodes - NASA's Mars Reconnaissance Orbiter has provided 3D images of the north-polar ice layers of Mars. The images provide validation for theoretical models of Mars' climate cycles over the past few million years. With accurate climate models, scientists can help determine whether or not Mars was once a habitable environment for life. See article.
g Message - What’s it like to be a SETI astronomer, listening for alien radio signals? See article. Note: This article is from 1998.
g Cosmicus - During the 2009 AMASE Expedition to Svalbard, scientists were able to carry out 'fun science' activities in addition to their normal research schedule. In this report, team member Juan Diego Rodriguez-Blanco discusses projects like 'iceberg chasing' and developing Raman spectroscopy for Mars. See article.
g Aftermath - Have you ever wanted to put a new word in the dictionary? Now's your chance: say hello to astrobioethics, a branch of ethics involving the implications of life science in space. See article.
