NASA's Space Sunflower may help snap pictures of planets

A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif.

Perhaps we shouldn't be surprised that the fast-growing, brilliantly bright sunflower offers guidance on how best to gather solar energy.
