How do we find Earth-like planets outside our solar system? One idea is to send a giant structure that blocks starlight so that astronomers can more easily detect orbiting planets. This artist's rendering shows the proposed starshade concept flying in sync with a space telescope. The giant sunflower-like structure would be used to acquire images of Earth-like rocky planets around nearby stars. The proposed starshade could launch together with a telescope. Once in space, it would separate from the rocket and telescope, unfurl its petals, then move into position to block the light of stars. http://photojournal.jpl.nasa.gov/catalog/PIA20911
