The search for exoplanets is about reach the next level with the Gemini Planet Imager, a new smart-car-sized telescope instrument that will use “extreme” adaptive optics to directly see distant planets around other stars.
Most large telescopes on Earth use adaptive optics — mirrors that wiggle a thousand times a second — to compensate for distortion from the atmosphere that causes the familiar “twinkling” effect of stars. With the technology, fuzzy globs of starlight are transformed into sharp pinpoints. GPI will take the method a step farther, using a mirror made from advanced silicon microelectromechanical systems (MEMS) instead of glass.
