The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets.Scientific investigation began shortly after the advent of radio in the early 1900s, and focused international efforts have been ongoing since the 1980s.

SETI Researchers Are Simulating Alien Contact — and You Can Help

SETI's new machine learning algorithm works like Google's "reverse image search" on a galactic scale, and has already uncovered eight currently unexplained signals. Researchers train the algorithm on simulated alien signals, then look back through old data to see if we missed anything in the noise.

SETI finds eight potential alien signals

SETI researcher Brian Lacki proposes a new hypothesis for Type 3 Civilizations. "My thought was you harvest molecular clouds where material is relatively easier to collect." These free floating "dust" particles are networked together across huge distances. ‘In a sense the galaxy could become alive.’

Extragalactic SETI looks for life beyond the Milky Way. But where? In game theory one solution is a Schelling point — a single event that draws different group's attention. A binary neutron star merger could act as one because observers across the universe will all be looking in the same direction.

The Wow signal is SETI's founding myth. Most have dismissed it, but for 35 years, until his death last year, one man never stopped searching. Bob Gray's final research, "Could the "Wow" signal have originated from a stochastic repeating beacon?" was published in June with astronomer David Kipping.
