Exoplanets: The Search for Another Earth

Technologically there’s never been a better time to search for a new earth beyond our solar system.

Professor Danielle George examines exoplanets in the so-called habitable zone. Those that have liquid water. And maybe even life.

She wonders how we might be able to take the our first ever high resolution picture of an exoplanet using the microchips found in mobile phones. And she meets world-leading astrophysicists to ask if within our lifetimes humans might step foot on an earth-like planet.
