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 - As a star grows older, its rotation slows down steadily. Now, astronomers have discovered how to use this principle to determine the age of stars. The research could ultimately help astrobiologists understand the nature of planets and the stars they orbit. See article.
g Abodes - New visualizations of the Earth from space provide a unique image of how the Earth has changed over the past 750 million years. See article.
