Alien Interception of Human Space Transmissions Imminent, Warns Study.

Researchers from UCLA and UC Berkeley have examined the likelihood of extraterrestrial intelligent civilizations intercepting outward transmissions from NASA's Deep Space Network (DSN) that are aimed at five deep space spacecraft: Voyager 1, Voyager 2, Pioneer 10, Pioneer 11, and New Horizons. The researchers used a combination of transmission beamwidth between the DSN and the five spacecraft, spacecraft telemetry data from the JPL Horizons System, and data from the Gaia Catalogue of Nearby Stars (GCNS) to ascertain which stars will intercept the outward DSN transmissions from Earth. The researchers identified the number of stars each spacecraft transmission will encounter as the signals endlessly traverse the cosmos at the speed of light.
