Astronomers to sweep entire sky for aliens for the first time, using 28 giant radio telescopes

The project is a collaboration between the privately-funded Seti Institute and the Very Large Array observatory in New Mexico, one of the world’s most powerful radio observatories. Gaining real-time access to all the data gathered by VLA is considered a major coup for scientists hunting extraterrestrial lifeforms and an indication that the field has “gone mainstream”.

Normal astronomy operations will continue at the VLA, which was featured in the 1997 film Contact, but under the new arrangement all data will be duplicated and fed through a dedicated supercomputer that will search for beeps, squawks or other signatures of distant technology.

“Determining whether we are alone in the universe as technologically capable life is among the most compelling questions in science, and [our] telescopes can play a major role in answering it,” said Tony Beasley, director of The National Radio Astronomy Observatory, which runs the VLA.

Stephen Hawking warned against attempting any form of contact, suggesting the outcome for humans would not necessarily be good. Siemion, director of the Berkeley Seti centre disagrees. “Personally I think we absolutely should and I think without a doubt, we would,” he said. “Part of being human is wanting to reach out into the unknown and wanting to reach out and make connections.”

He is less decisive about what Earth’s message should be, however. “I don’t know … I spend absolutely zero time thinking about that,” he said. “I guess I would just say, ‘Hello’.”
