Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth.

Topic hierarchy

8.2A: Mars and a Biosphere
Mars, the fourth planet from the Sun, is currently undergoing a great deal of investigation concerning its capacity for maintaining life.
8.2B: Martian Biosignatures
A biosignature, a substance that provides scientific evidence of past or present life, is present in the form of fog on the planet Mars.
8.2C: Terraforming Mars
Terraforming Mars is the hypothetical idea that Mars could be altered in such a way to sustain human and terrestrial life forms.
8.2D: Europa's Possible Ocean
Europa, one of Jupiter’s four moons, is covered by a layer of ice/water and scientists have multiple hypotheses to explain its structure.
