The list of known planets outside our Solar System grows by the week. Thanks to new technologies, a host of pictures of these worlds could soon be available. Tony Reichhardt investigates.

Soon after the first planet orbiting a Sun-like star was discovered, Dan Goldin, then administrator of NASA, issued a challenge. At a meeting of the American Astronomical Society (AAS) in San Antonio, Texas, in January 1996, he called on the assembled scientists to find a way, within 25 years, to take a picture of an Earth-sized planet orbiting a nearby star with a resolution good enough to see oceans, clouds, continents and mountain ranges.
