extraterrestrial life
Life beyond Earth
Extraterrestrial life is life that originates outside Earth—on other planets, moons, or elsewhere in the universe.
The term covers everything from microbes in Martian soil to intelligent beings capable of interstellar contact.
Scientists search for extraterrestrial life through radio signals, atmospheric analysis, and exploration of potentially habitable worlds: Is there extraterrestrial life in our solar system?
