Extraterrestrial Life

Extraterrestrial life refers to any form of life, whether intelligent or simple, that originates from outside Earth. This concept encompasses a wide range of possibilities, from microbial organisms on other planets and moons to advanced civilizations capable of interstellar communication or travel. The search for extraterrestrial life involves various scientific fields, including astrobiology, astronomy, and planetary science, as researchers explore environments beyond Earth that may support life, such as Mars, the icy moons of Jupiter and Saturn, and exoplanets within habitable zones around distant stars. The existence of extraterrestrial life raises profound questions about the nature of life, biological processes, and the potential for life forms to evolve under different environmental conditions throughout the universe.
