A Radio Search for Artificial Emissions from 'Oumuamua

MOUNTAIN VIEW – It’s the first time a visitor from another star system has been seen nearby. But what is it? An asteroid, a comet … or an alien artifact?

Humpback Whale Communication and the Search for Alien Intelligence

Long before the discovery of the first planet beyond our Solar System, SETI Institute research scientist Laurance Doyle began theorizing about the habitability of planets around other stars, clarifying the conditions needed for a planet

Artificial Intelligence Helps Find New Fast Radio Bursts

New detections mark the first time that machine learning techniques have been used to directly detect a fast radio transient.  Successful application of

Why Aliens might turn to star collecting to save themselves

It’s often said that the search for aliens is too parochial — that our continuing efforts to locate cosmic radio broadcasts or laser beams are really just quests for analogs of ourselves.

FRB 121102: Radio Calling Cards from a Distant Civilization?

It’s a signal that begs for superlatives.  The Breakthrough Listen project recently announced the detection of 15 pulses of radio energy from an object known to the astronomy community as FRB 121102.

What’s Up with Tabby’s Star?

By now you have surely heard that Boyajian’s star, aka Tabby’s star, aka KIC8462852, is going through another weird dimming phase.

Arecibo Message

In 1974, the most powerful broadcast ever deliberately beamed into space was made from Puerto Rico. The broadcast formed part of the ceremonies held to mark a major upgrade to the Arecibo Radio Telescope.
Galactic Center

SETI on the ATA: Galactic Center Survey

The region near the center of our galaxy contains the highest concentration of stars in the sky, yet has only been searched for ETI signals at a few “magic” frequencies. We will search a large area near the galactic center over the entire “waterhole” frequency range, from 1420 to 1720 MHz.
