Largest submillimetre telescope

Beyond the red end of the visible spectrum of light lies infrared radiation, microwaves and radio waves. The largest telescope designed to study the universe at the wavelengths between the far infrared and microwaves the submillimetre region, is the James Clerk Maxwell Telescope, on Mauna Kea, Hawaii. Rather than an optical mirror, it uses a massive 15-m (49-ft) dish to collect submillimetre radation.
