You can easily recognize the JCMT by the world's largest sheet of Gore-Tex® which covers the telescope allowing it to operate night and day. Its 49.2ft mirror captures submillimeter wavelengths, and specialized instruments can detect distant cold objects. Initially funded by the UK, Canada and the Netherlands, in 2015 it was handed over to the East Asian Observatory.
