New data supports liquid water ocean on Enceladus and the microwave band

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - New data from Cassini supports the theory that Saturn's moon Enceladus has liquid water beneath its surface. Water is essential for life, and determining locations of liquid water is the first step in the search for life in our solar system. See article.
g Message - The universe is a noisy place, filled with the hiss and crackle of stars being born and dying. There is little escape from this cosmic din, except in one small region of the radio dial — the microwave band. Here, only the faint whimper of the Big Bang breaks the silence, making it a “really good place to communicate,” according to Dan Werthimer of Berkeley’s Space Sciences Laboratory, perched close to the stars atop Grizzly Peak. See article. Note: This article is from 2000.
g Imagining - What is panspermia, a concept that appears in a number of science fiction stories, and how plausible is it? See article.
g Aftermath - Here’s an interesting book for some astrobiological reading: “After Contact: The Human Response to Extraterrestrial Life” by Albert A. Harrison.

Honoring the Past, Inspiring the Future
