Global warming in 47 million BC and the Drake Equation

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 - What is the habitable zone for the nearby star system GJ 2139 ABC?
g Abodes - Research suggests that a period of global warming strongly influenced plants and animals some 53 million to 47 million years ago during the Eocene epoch. The study could help scientists understand the effects that climate change will have in Earth's future. See article.
g Message - Is there life "out there"? If so, is it intelligent life? One way we can address the issue is to make a reasoned guess, based upon everything we know about astronomy, physics, chemistry, biology, and a host of other disciplines. Many years ago the radio astronomer Frank Drake did just this, combining all the "knowledge" in the form of a mathematical equation now named for him: The Drake Equation. See article.
g Cosmicus - NASA has cleared space shuttle Discovery for liftoff Tuesday, and the weather looks promising as long as thunderstorms stay away during fueling. See article.
g Aftermath - Here’s something I dug up from the Toronto Star in 2002 article: “Discovery Of Extraterrestrial Life Could Have Profound Impact On Religion” by reporter on the religion beat.
