Glow of universe’s first objects, Titan’s mountains and recognizing an alien intelligence

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 Stars - New observations from NASA's Spitzer Space Telescope strongly suggest that infrared light detected in a prior study originated from clumps of the very first objects of the universe. The recent data indicate this patchy light is splattered across the entire sky and comes from clusters of bright, monstrous objects more than 13 billion light-years away. See article.
g Abodes - NASA has released images of mountains on Titan that are coated with layers of organic material and blanketed by clouds. The images reveal a number of additional geological features, including dunes and material that resembles a volcanic flow. See http://www.

g Message - Most people see the Search for Extraterrestrial Intelligence as a project for merely listening for signals from other stars, but Yvan Dutil and Stephane Dumas from the Defence Research Establishment Valcartier in Canada had other ideas in mind when they composed a message recently sent to the stars. See http://www.ibiblio.org/astrobiology/print.php?page=interview01.
g Learning - Here’s a neat set of classroom activities: Life On Other Planets in the Solar System. It examines the possibility of life on other planets in our own solar system and what form that life might take. Designed as a curriculum resource for middle and high school students. See http://www.resa.net/nasa/.
g Imagining - Here’s a neat Web page that asks “What are our chances of actually recognizing an alien intelligence for what it is?” What if ET does not say "Take me to your leader" from an obviously technologically superior spaceship? Will we know if it’s intelligent? It draws in part upon Stanley Weinbaum's famous short story, "A Martian Odyssey.” See http://www.sff.net/people/mmolvray/exobio/recog.htm.
g Aftermath - If we find other civilizations, what will we say to them? Crafting a message that represents Earth and humanity and can be understood by another life form is no minor endeavor. SETI Institute psychologist Douglas Vakoch has been charged with this formidable task, and has enlisted the help of mathematicians, artists, astronomers and anthropologists.
