Other forms: astrobiologists

A scientist who specializes in studying life in the universe is an astrobiologist. Many astrobiologists focus on searching for evidence of life beyond the earth.

People who become astrobiologists are entering a brand new scientific field. Astrobiology combines many other disciplines, including chemistry, geology, and paleontology — as well as astronomy and molecular biology, from which its name was derived. Astrobiologists are fascinated by the origin and evolution of life, its existence in the universe, and the possibility of humans living on other planets, among many other topics.
