Dramatically Cooler Early Earth And Imagining An Ecosystem On Alpha Centauri

Dramatically Cooler Early Earth And Imagining An Ecosystem On Alpha Centauri
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 - Features discovered in 3.4 billion-year-old rocks indicate that temperatures on early Earth may have been dramatically cooler than previously believed. The finding could have implications in understanding the conditions in which life first evolved on our planet. See article.

g MESSAGE - Among the most important SETI work is being done at Harvard University. The Harvard SETI home page discusses the Radio Search for Extra-Terrestrial Intelligence, The Arecibo Search for Early Hydrogen and Optical SETI.

g COSMICUS - Equipped with wearable AI systems and digital eyes that see what human eyes can't, space explorers of the future could be not just astronauts, but "cyborg astrobiologists." See article.

g IMAGINING - "Avatar", a film by former NASA Advisory Committee member James Cameron, will debut across the planet on 18 December. Widely hailed as "ground breaking" the film may well push the boundaries of what can be portrayed on the big screen. The film centers around humans mining precious materials on a world in the Alpha Centauri star system - and the inevitable conflict that arises with the local (sentient) inhabitants. The film delves into a wide range of issues that intersect with what NASA's Astrobiology Institute and Exobiology Programs have looked into in one way or another. See article.

g AFTERMATH - Quote of the Day: "This is the century for the discovery of extraterrestrial life. It is an incredibly exciting time." - Conway Morris
