Pluto’s atmosphere and the Spirit rover’s new discoveries

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Scientists have made surprising discoveries about the atmosphere of the dwarf planet Pluto. The atmosphere contains unexpectedly large amounts of methane and is much warmer than the surface of Pluto itself. See article.
g Life - Animals shrunken by the evolutionary pressures of hunting and fishing could someday recover their lost splendor. See article.
g Cosmicus - Loose soil is forcing NASA's Spirit rover to take the long way around to its next study site. However, Spirit is already making new discoveries that will help scientists determine if the past environment of Mars was once capable of supporting life. See article.
