Asteroid triple threat and messages composed for aliens

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 Message - Visiting another civilization on a distant world would be fascinating, but at present such a trip is beyond our capabilities. However, it is perfectly within our capabilities to develop a communications system using a powerful transmitter and a sensitive receiver, and using it to search the sky for alien worlds whose citizens have a similar inclination. See article.
g Cosmicus - Asteroid 2001 SN263 has now been identified as the first ever near-Earth triple asteroid. Observations of the asteroid triplet are yielding surprising new insights about the asteroid belt between Mars and Jupiter. See article.
g Imagining - The first step in imagining what a real alien might look like is to forget you ever watched the "The X-Files." They won't be the sinister grays Fox Mulder pursues, little green men or even jolly old E.T. And most assuredly they won't look like us. See article. Note: This article is from 1999.
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. Hear the messages he helped compose and learn about the thinking behind them.
