xenobiology
Extraterrestrial life research
Xenobiology is the study of life forms that originated beyond Earth—extraterrestrial organisms, if they exist.
The field remains largely theoretical, since no alien life has been confirmed, but it encompasses how scientists might recognize, classify, and understand such organisms.
In science fiction, xenobiology often appears as an established discipline: The ship's xenobiologist examined the creature.
