Astrobiology is the scientific field that studies the potential for life beyond Earth. This interdisciplinary science combines biology, chemistry, and space exploration to understand the conditions necessary for life to exist elsewhere in the universe. Scientists explore extreme environments on Earth to gain insights into how life might survive on planets like Mars or in the subsurface oceans of moons like Europa.
One of the most exciting possibilities in astrobiology is the discovery of microbial life, which could exist on planets or moons with conditions drastically different from Earth. The search for alien life continues with missions to Mars, Europa, and beyond, pushing the boundaries of our understanding of life in space.
