Are we Alone?


We are on an extraordinary journey that may answer the age-old question of whether there is life elsewhere in the universe. Already, we have found over 100 planets orbiting other stars, and we are getting ready to launch amazing missions that will allow us to view these worlds and tell if they support life.

Join us on a quest
that extends from our own planet

—where life exists wherever we look
—to the far reaches of space.
