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 - Astrophysicists have spotted four white dwarf stars surrounded by dust from shattered planetary bodies that once bore similarities to the composition of the Earth. See article.
g Abodes - A new technique for observing electromagnetic signatures on Earth could be used to study other planets in the Solar System. See article.
g Life - Sauropod dinosaurs could in principle have produced enough of the greenhouse gas methane to warm the climate many millions of years ago, at a time when Earth was warm and wet. That's according to calculations reported in the May 8th issue of Current Biology, a Cell Press publication See article.
