extraterrestrial origin
Beyond Earth's atmosphere
Extraterrestrial origin describes something that came from beyond Earth—from outer space rather than from our planet.
The phrase appears most often in scientific contexts discussing meteorites, cosmic dust, or theories about how life began: Scientists confirmed the rock's extraterrestrial origin based on its isotopic composition.
It also features heavily in speculation about UFOs and alien life forms, where claims of extraterrestrial origin are typically met with skepticism.
