Astrobiology is the study of life in the universe. Scientists in this field explore whether life exists outside Earth and how it might survive on other planets or moons.
Astrobiologists look for places in space that could support life. This includes planets and moons with water, the right temperatures, and the right chemicals, as these are essential for life as we know it.
Water is crucial for life. Scientists search for signs of water, like ice or liquid water, on other celestial bodies. For example, scientists believe that Jupiter’s moon, Europa, has a vast ocean beneath its icy surface.
Researchers study extreme environments on Earth, like hot springs and deep-sea vents, to understand how life can survive in harsh conditions.
Astrobiologists use telescopes and space missions to look for signs of life, such as chemicals in the atmosphere of distant planets.
Astrobiology also investigates how life began on Earth. By understanding this process, scientists can better theorize how life might develop elsewhere in the universe.
Some astrobiologists look for intelligent life forms. They use radio telescopes to listen for signals from other civilizations.
