1998 The Keck telescope is a pair of twin 10 metre, multi-segmented mirror
telescopes. Work is now in progress to link the two main scopes
with four 1.8 m outrigger scopes to form an interferometer. When fully
operational, the system will be able to resolve Jupiter sized planets
around neighbourhood stars.
