If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxies.

The Breakthrough Prize Foundation and its founder, internet investor Yuri Milner, have signed a contract with the University of California, Berkeley, to lead a major escalation in the search for extraterrestrial intelligence, or SETI.

After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced civilizations in them.

Astronomers have expanded the search for extraterrestrial intelligence into a new realm with detectors tuned to infrared light. Their new instrument has just begun to scour the sky for messages from other worlds.

The vast collecting area of the Square Kilometre Array (SKA), harnessed by sensitive receivers, flexible digital electronics and increased computational capacity, could permit the most sensitive and exhaustive search for technologically-produced radio emission from advanced extraterrestrial intelligence (SETI) ever performed.

When astronomers conducting the search for extraterrestrial intelligence (SETI) find other cultures in the universe, could we understand their messages?

One of the beneficial outcomes of searching for life in the Universe is that it grants greater awareness of our own problems here on Earth.

In 1930, Albert Einstein was asked for his opinion about the possibility of life elsewhere in the universe. "Other beings, perhaps, but not men," he answered. Then he was asked whether science and religion conflict. "Not really, though it depends, of course, on your religious views."

Associated Universities, Inc. (AUI), and the National Radio Astronomy Observatory (NRAO) have awarded the 2014 Karl G. Jansky Lectureship to Dr. Jill C. Tarter, of the SETI Institute. The Jansky Lectureship is an honor established by the trustees of AUI to recognize outstanding contributions to the advancement of radio astronomy.

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.

John Billingham

Keith's note: NASA sources report that John Billingham has passed away. John ran the SETI Program Office when NASA used to do SETI. He also ran life science at NASA Ames.

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.
