A flower-shaped spacecraft may help scientists see Earth-like alien worlds like never before.

Called a “starshade,” the huge, sunflower-like spacecraft would deploy to its full size in space, blocking the light of distant stars so that a space-based telescope can image exoplanets in orbit around the stars. With this technology, researchers could directly image other worlds and potentially find long sought-after Earth twins, a historically difficult task for alien planet hunters.
