While we await with interest a formal write-up of the RATAN-600 result, the claim that the detection could be a signal from an extraterrestrial civilization has attracted much media interest.

A spectral line image cube generated from 115 minutes of MWA data that covers a field of view of 400 sq. deg. around the Galactic Centre is used to perform the first Search for ExtraTerrestrial Intelligence (SETI) with the Murchison Widefield Array.

We report radio SETI observations on a large number of known exoplanets and other nearby star systems using the Allen Telescope Array (ATA) for about 19000 hours from May 2009 to Dec 2015.

We employed the SERENDIP III system with the Arecibo radio telescope to search for possible artificial extraterrestrial signals. Over the four years of this search we covered 93% of the sky observable at Arecibo at least once and 44% of the sky five times or more with a sensitivity of ~3E-25 W/m2.

Over the past few years, astronomers have detected thousands of planets and planet candidates by observing their periodic transits in front of their host stars.

The F-type star KIC~8462852 has recently been identified as an exceptional target for SETI (search for extraterrestrial intelligence) observations.

Globular clusters are ancient stellar populations with no star formation or core-collapse supernovae. Several lines of evidence suggest that globular clusters are rich in planets.

Why did the emergence of our species require a timescale similar to the entire habitable period of our planet?

Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU).

"A globular cluster might be the first place in which intelligent life is identified in our galaxy," says lead author Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics (CfA).
