Freakishly Old System Of Planets Hint At Ancient Alien Civilizations

Kepler scientists have discovered the oldest known system of rocky, Earth-sized planets in the Milky Way. This suggests that terrestrial planets have appeared throughout most of the Universe's 13.8 billion year history — a potential indication of just how ancient some extraterrestrial civilizations could be. »1/27/15 11:00am1/27/15 11:00am

Two Billion Reasons Why We're About to Find Earth 2

Planet-hunting scientists announced today that 22% of sunlike stars in the Milky Way are orbited by potentially habitable, Earth-size worlds. This remarkable finding indicates that there may be as many as two billion planets in our galaxy suitable for life — and that the nearest such planet may be only 12 light-years… »11/04/13 4:42pm11/04/13 4:42pm

SETI Conducts First Ever Targeted Search For Intelligent Life On Earth-Like Planets

In what is its most targeted search to date, the SETI Institute has scanned 86 potentially habitable solar systems for signs of radio signals. Needless to say, the search came up short (otherwise the headline of this article would have been dramatically different), but the initiative is finally offering some… »2/08/13 3:24pm2/08/13 3:24pm

Astronomer discovers three potentially habitable planets orbiting around one red dwarf

Canadian astronomer Philip Gregory has confirmed that there are three habitable zone planets orbiting the red dwarf star Gliese 667C. The star, which is part of a trinary star system, is only 22 light-years away and it features a planet that's only twice the mass of Earth — making it the lowest mass planet found in a… »12/18/12 12:00pm12/18/12 12:00pm

Newly discovered super-Earth is one of the best candidates for life yet

European astronomers using the HARPS planet searcher have detected a super-Earth orbiting an orange dwarf star that's only 44 light years away. The researchers aren't entirely sure if it's a rocky planet or not, but it does have a number of key features that make it an excellent candidate for life, including its… »11/08/12 10:00am11/08/12 10:00am

Further evidence that there are many habitable planets for humans to colonize

An international team of scientists working at European HARPS have announced the discovery of a large rocky planet residing within the stellar habitable zone of the red dwarf star Gliese 163. That increases the number of known potentially habitable planets to six — the majority of which have been discovered in the… »8/31/12 5:30pm8/31/12 5:30pm
