Giant "starshade" could reveal new exop***ts Jul 5
An astrophysicist in the US has devised an unusual way to spot extrasolar p***ts -- by blocking the light from their parent star with a space-based shield. Webster Cash of the University of Colorado says that a thin, sunflower-shaped plastic screen measuring about 50 metres across could be enough to allow p***ts as small as the Earth to be observed directly. The big snag is that the shield, dubbed a starshade, would have to be attached to a spacecraft and placed tens of thousands of kilometres away from a space telescope. Cash's design may sound like science fiction, but it has already received a $400,000 funding boost from NASA (Nature 442 51).
