So CNN reports that a group of astronomers have developed a short list for more focused study of existence of extraterrestrial life forms. The lead astronomer in the groups indicates that they should looks for life "not as we know it". I find that interesting, but amusing. I and others I have dealt with have always wondered why we're looking for life forms that somewhat resemble those here on Earth. It always seemed to be a mild annoyance to me personally that we'd think aliens would have appendages, eyes, nose etc etc.
In any case, here is the list of star systems they want to target:
Five top candidate stars for those listening for radio signals from intelligent civilizations: 1. beta CVn: A sun-like star about 26 light-years away in the constellation Canes Venatici (the Hound Dogs). 2. HD 10307: A star about 42 light-years away.3. HD 211415: About half the metal content of sun and a bit cooler, this star is in just a little farther away than HD 10307. 4. 18 Sco: The star, in the constellation Scorpio, is almost an identical twin to our sun. 5. 51 Pegasus: In 1995, Swiss astronomers reported they had detected the first planet beyond our solar system in orbit around 51 Pegasus. Five candidates for those trying to detect Earth-like planets in orbit around nearby stars: 1. epsilon Indi A: A star only about one-tenth as bright as the sun. It is about 11.8 light-years away in the constellation Indus. 2. epsilon Eridani: A star somewhat smaller and cooler than our sun, located about 10.5 light-years away in the constellation Eridanus (the River). 3. omicron2 Eridani: A yellow-orange star about 16 light-years away, roughly the same age as our sun. 4. alpha Centauri B: Long considered one of the places in the Milky Way that might offer terrestrial conditions. This star is part of a triple star system. 5. tau Ceti: A G-class star with the same brightness category as our sun.
