Ultraviolet Light May Be Ultra Important In Search For Life

surface of a planet orbiting a red dwarf

This artist's impression shows how the surface of a planet orbiting a red dwarf star may appear. The planet is in the habitable zone so liquid water exists. However, low levels of ultraviolet radiation from the star have prevented or severely impeded chemical processes thought to be required for life to emerge. This causes the planet to be devoid of life.
