Are we an exhibit for alien tourists and how our planet became conducive to life

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 - Cosmologists have used the distorted shapes of primordial galaxies to "weigh" the distribution of unseen matter in the early universe and confirm the existence of mysterious "dark energy." See article.
g Abodes - As a faculty member at the University of Hawaii at Manoa and the leader of the UH branch of NASA’s Astrobiology Institute, Karen Meech considers some of the biggest of the big questions. One of her main areas of interest is water, and how its presence makes planets conducive to life. Next week, she’s giving a talk titled, “When and How Did Our Planet Become Conducive to Life?” as part of the Institute for Astronomy’s Frontiers of Astronomy Lecture series. Honolulu Weekly caught up with Meech beforehand to talk about everything from subsurface oceans to UFOs. See interview.
g Message - A resolution for the so-called Fermi Paradox is that we’ve been singled out for special treatment: we are an exhibit for alien tourists or sociologists. Our world may be known to the extraterrestrials, but they observe us through a sophisticated type of one-way mirror. See article. Note: This article is from 2001.
g Learning - Do you have a children with a question about a topic in astronomy or about an object in space? You may find the answer under one of the categories at “Ask an Astronomer for Kids”.
