CNN.com incorrectly headlined this Reuters article as, "Astronomers get ET 'top 10' list". Actually, it's a list (the second group below) of nearby stellar systems with potential to contain earth-like planets, listed for priority peeps by the Terrestrial Planet Finders, NASA orbital observatories expected to be launched in 2014 and 2020. ET don't come into it. Probably.
I imagine the list takes into account a desire to eventually launch interstellar probes, also.
quote:
TURNBULL'S 'TOP 10' LIST:
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.
