Are we alone? Are there other planets like ours? Does life exist elsewhere in the universe?
Every new discovery of a planet beyond our solar system helps us refine our notion of the cosmos and understand humankind’s place within it. JPL is at the forefront of efforts to discover Earth-like planets, enabled by our work in developing the technologies and next- generation telescopes to detect and characterize habitable planets, measure their atmospheres, and find the chemical signposts of life.
