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.

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.

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.
