We describe the framework and strategy of the \^G infrared search for extraterrestrial civilizations with large energy supplies, which will use the wide-field infrared surveys of WISE and Spitzer to search for these civilizations' waste heat.

Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished by life.

The question of whether we share the universe with other intelligent beings is of long standing.

SETI experiments are trying to determine whether other intelligent, technologically capable, life exists in the universe, to answer the question "Are we alone?" or "Is anybody out there?"

The Search for ExtraTerrestrial Intelligence (SETI) project is an initiative that began in the 70s with funding from NASA, but that has evolved towards the collaboration of millions of Internet users for the processing of data from the Arecibo Observatory (Puerto Rico), where space tracking is carried out.

Until recently, one of the ultimate mysteries of the universe -- how many civilizations may exist on planets orbiting other stars in the Milky Way Galaxy -- relied on the possibility of detecting intelligent beings by radio signals. Now a team of astronomers, engineers, and physicists from the University of Hawaii, the University of Freiburg, and elsewhere has proposed a new and powerful technique to search for intelligent life.

Survey: Life Exists On Other Planets

58% Believe Life Exists On Other Planets, Rasmussenreports.com

Survey of 1,000 Adults

* 58% of American Adults think it's at least somewhat likely life exists on other planets; 34% do not believe it's likely
* That number includes 33% who say it's Very Likely life exists outside of Earth and 8% who believe it's Not At All Likely
* 49% say it's likely that a human will walk on Mars in the next 25 years, down slightly from December 2006
* 42% think it's unlikely a human will make it to Mars, that includes 20% who say it's Very Likely and 8% who believe it's Not At All Likely

Budget crunch mothballs telescopes built to search for alien signals, Scientific American

"The hunt for extraterrestrial life just lost one of its best tools. The Allen Telescope Array (ATA), a field of radio dishes in rural northern California built to seek out transmissions from distant alien civilizations, has been shuttered, at least temporarily, as its operators scramble to find a way to continue to fund it. In an April 22 letter to donors, Tom Pierson, CEO of the SETI Institute in Mountain View, Calif., explained that the ATA has been put into "hibernation," meaning that "starting this week, the equipment is unavailable for normal observations and is being maintained in a safe state by a significantly reduced staff." The ATA is a partnership between the SETI Institute, which is responsible for building the telescope array, and the University of California, Berkeley, which is responsible for operating it."
