Astronomers at the University of California, Berkeley are aiming a radio telescope to detect signals of alien life on 86 possible Earth-like planets. The search began on Saturday, May 8, when the Robert C. Byrd Green Bank Telescope - the largest steerable radio telescope in the world – dedicated an hour to
“We’ve picked out the planets with nice temperatures - between zero and 100 degrees Celsius - because they are a lot more likely to harbor life,” said physicist Dan Werthimer.
The United States has inaugurated a massive radio telescope in rural West Virginia to listen for signs of extraterrestrial life on 86 Earth-like planets.
US astronomers said on Friday that the colossal dish will gather 24 hours of data on each of the planets, which have been selected from a list of 1,235 planets identified by NASA's Kepler space telescope, AFP reported.
''It's not absolutely certain that all of these stars have habitable planetary systems, but they're very good places to look for ET,'' said Andrew Siemion, a graduate student at the University of California, Berkeley, on Friday.
Using the prolific planet hunting Kepler spacecraft, astronomers have discovered 1,235 candidate planets orbiting other suns since the Kepler mission's search for Earth-like worlds began in 2009.
To find them, Kepler monitors a rich star field to identify planetary transits by the slight dimming of starlight caused by a planet crossing the face of its parent star.
In this remarkable illustration, all of Kepler's planet candidates are shown in transit with their parent stars ordered by size from top left to bottom right.
Simulated stellar disks and the silhouettes of transiting planets are all shown at the same relative scale, with saturated star colors. Of course, some stars show more than one planet in transit, but you may have to examine the picture at high resolution to spot them all.
For reference, the Sun is shown at the same scale, by itself below the top row on the right. In silhouette against the Sun's disk, both Jupiter and Earth are in transit.
Roughly one out of every 37 to one out of every 70 sunlike stars in the sky might harbor an alien Earth, a new study reveals.
These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added.
These new calculations are based in data from the Kepler space telescope, which in February wowed the globe by revealing more than 1,200 possible alien worlds, including 68 potentially Earth-size planets. The spacecraft does so by looking for the dimming that occurs when a world transits or moves in front of a star.
Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., focused on roughly Earth-size planets within the habitable zones of their stars — that is, orbits where liquid water can exist on the surfaces of those worlds.
After the researchers analyzed the four months of data in this initial batch of readings from Kepler, they determined that 1.4 to 2.7 percent of all sunlike stars are expected to have Earthlike planets — ones that are between 0.8 and two times Earth's diameter and within the habitable zones of their stars.
"This means there are a lot of Earth analogs out there — two billion in the Milky Way galaxy," researcher Joseph Catanzarite, an astronomer at NASA's Jet Propulsion Laboratory, told SPACE.com. "With that large a number, there's a good chance life and maybe even intelligent life might exist on some of those planets. And that's just our galaxy alone — there are 50 billion other galaxies."
Easing us into disclosure/bluebeam is my bet, and i'd bet the bank.
I will be a part of sending someone to Mars, that you can count on!

I wont them to do it all live with web cams.
so we can see it. no hiding the truth.
why are they useing SETI
to build up fauls hopes?
so no one trys any other ideas?

I smell something fishy, why start up again?
Probably the same reason ET fiction is being shoved down our collective throats. (Just look at a list of movies for 2011-theres the proof)

He stated, "We will be looking at a much wider range of frequencies and signal types than has ever been possible before,” adding that the surface of the telescope is 100 by 110 meters and it can record nearly one gigabyte of data per second.
