Q. Study of life in outer space is known as

Explanation by: Mr. Dubey

The study of life in outer space is known as:
 
Astrobiology: This is the most commonly used and encompassing term. Astrobiology is an interdisciplinary field that studies the origins, evolution, distribution, and future of life in the universe.
 
Exobiology: This term is also used, and it specifically refers to the study of the possibilities of life beyond Earth. While sometimes used interchangeably with astrobiology, astrobiology is considered the broader field.
Therefore, both astrobiology and exobiology are correct, but astrobiology is the more current and widely used term.
