The group leading the charge in the search for extraterrestrial life has given the all clear. The SETI Institute said Wednesday that extensive radio scans by its telescope in Northern California have found no signs of alien tech from our solar system’s latest interstellar visitor. The object labeled 3I/Atlas was discovered last summer sweeping through our neck of the cosmic woods. Scientists identified it as a comet that migrated from another star. SETI says it conducted more than seven hours of observations, searching through a wide range of radio signals. But no evidence of extraterrestrial technology was found.
