As an alternative of a shiny tube, the Webb Telescope seems to be like an enormous honeycomb using on a silver surfboard. The quick reply to why it seems to be like that’s: It must be very large and really chilly.
Within the video above, NASA astrophysicist Amber Straughn and I construct a small mannequin of the telescope to discover its extraordinary design.
