For example, the James Clerk Maxwell Telescope observes from wavelengths from 3 μm (0.003 mm) to 2000 μm (2 mm), but uses a parabolic aluminum antenna. [20] On the other hand, the Spitzer Space Telescope, observing from about 3 μm (0.003 mm) to
Directed by Kris Koenig, it chronicles the history of the telescope from the time of Galileo and features interviews with leading astrophysicists and cosmologists from around the world, who explain concepts ranging from Galileo's first use of the telescope to view the moons of Jupiter, to the latest discoveries in space, including new ideas ...
