Extra ExTrA
ExTrA is a planet-hunter focused on finding Earth-sized planets orbiting nearby M dwarfs. The small size of these stars makes it easier to discover them using the transit method, because a planet covers a great proportion of the star's face than it would the face of a larger star. It's three .6m telescopes search the sky in infrared wavelengths of light—longer than our eyes can see, but where M dwarfs shine brightest.
