More than 1000 exoplanets, planets circling around stars other than the Sun, have been discovered since the first detection in 1995. Direct imaging is the ultimate way of studying such exoplanets. We need a special high-contrast imaging technique to image a faint planet close to a very bright star. The Extrasolar Planet Detection Project Office will develop the instruments for the study of exoplanets on the Subaru Telescope and future space missions, and promote their researches step-by-step from giant planets to Earth-like planets including planet formation sites. This is to answer questions such as “Are we alone in the Universe?” or “Are there other Earths that harbor life?”
