Star’s mysterious dark companion and how scientists will knowing they’ve heard ETI

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 - Astronomers have been given a glimpse of a "mysterious dark companion" in a distant solar system that has baffled fellow stargazers for nearly 200 years. See article.
g Abodes - Carl Sagan said that the weak rays of our Sun during Earth's early years should have created a planet ensconced in ice. Yet somehow Earth's temperature's been mostly constant, and above freezing. Now two Danish scientists think they know why. See article.
g Life - The enormous dragonflies, millipedes and other insects that lived 300 million years ago grew so large because of Earth's rich oxygen supply at the time. See article. Note: This article is from 2006.
g Message - How can scientists be sure they’ve picked up a signal from ETI, and not just the cosmic gurgle of a completely natural object? See article. Note: This article is from 2003.
g Cosmicus - Some travel agents have smartly reorganized their operations around Virgin Galactic's new plan to blast tourists into space from a rocket launch pad in New Mexico. See article.
g Learning - Here’s a neat classroom activity courtesy of NASA: “Measuring meteorological data from Mars”. Students compare real-time Earth and Mars weather measurements for temperature, wind speed, humidity and atmospheric pressure by accessing Internet-data resources from NASA.

My apologies to everyone ... for some strange reason, the format of my Blogspot posting box has changed, and it apprently no longer accepts my links unless I use html - it's very annoying. But the links are there now.
