Love science? Here’s an interesting talk about what we can know and understand about planets orbiting distant stars.

Astronomer Aomawa Shields searches for clues that life might exist elsewhere in the universe by examining the atmospheres of distant exoplanets. When she isn’t exploring the heavens, the classically trained actor (and TED Fellow) looks for ways to engage young women in the sciences using theater, writing and visual art. “Maybe one day they’ll join the ranks of astronomers who are full of contradictions,” she says, “and use their backgrounds to discover, once and for all, that we are truly not alone in the universe.”
