SETI

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 chief says US has no evidence for alien technology. 'And we never have'

A new paper argues that technology will not be possible on worlds with oxygen abundances less than 18%. Below this threshold fires will not burn, so metallurgy and technology as we know it will not develop. There could be intelligent life on these worlds, but no technosignatures for SETI to detect.

'It's getting closer and closer for sure.' How SETI is expanding its search for alien intelligence (exclusive)

The “COSMIC” system in New Mexico is spearheading a new SETI approach, now observing up to 3000 stars per hour, 24 hours a day, 7 days a week. Using a technique called `beamforming,’ COSMIC combines signals from 27 antennas to target areas of interest within the array’s field of view on the sky.

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.
