Three super-Earths discovered and how Fermi's Paradox was first asked

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 - What is the habitable zone for the nearby star system Groombridge 34 AB?
g Abodes - European researchers said on Monday they discovered a batch of three "super-Earths" orbiting a nearby star, and two other solar systems with small planets as well. See article.
g Message - Here's an account of how Fermi's famous question, "Where is everybody?" was first asked. Sorry in advance for the Web site that I found this on.
g Cosmicus - Good news for green tech: The fastest supercomputer in the world is also one of the most energy efficient. See article.
g Learning - Here's a neat lesson plan, "Extraterrestrials," in which students learn that a digital radio message has been electronically transmitted into space by the Arecibo radio dish in Puerto Rico and that the purpose of the message is to alert any intelligent life in space to the existence of intelligent life on Earth. See article.
g Aftermath - The statement that extraterrestrial intelligence exists or doesn't can have the parallel statement that God exists or doesn't. Some people say there's already sufficient evidence of existence for both. If you set aside abductions and miracles, it's true that the absence of evidence is not evidence of absence for either. However, if and when humanity ever detects evidence of an extraterrestrial intelligence, it will break the symmetry of these two statements and, in fact, that evidence will be inconsistent with the existence of God or at least organized religions. Note: This article is from 2004. See article.
