description James Clerk Maxwell Telescope Overview

The James Clerk Maxwell Telescope (JCMT) is a 15-meter astronomical observatory situated near the summit of Mauna Kea in Hawaii. As the largest single-dish telescope in the world operating in the submillimeter wavelength range, it specializes in observing distant galaxies, star formation, and interstellar dust. The facility is operated by the East Asian Observatory and serves an international community of astronomers seeking to study complex celestial phenomena that are invisible to optical telescopes.

help James Clerk Maxwell Telescope FAQ

Where is the James Clerk Maxwell Telescope located?

The James Clerk Maxwell Telescope is located near the summit of Mauna Kea on Hawaii Island. It operates at an altitude of roughly 4,100 metres, where the dry air is useful for submillimetre astronomy.

What does the James Clerk Maxwell Telescope observe?

The JCMT observes submillimetre radiation rather than ordinary visible light. This allows astronomers to study cold dust, molecular clouds, star formation, and distant dusty galaxies.

How large is the James Clerk Maxwell Telescope?

Its primary dish is 15 metres across. That makes it one of the major single-dish facilities dedicated to submillimetre observations.

Who operates the James Clerk Maxwell Telescope?

The telescope is operated by the East Asian Observatory on behalf of partner institutions. It is part of the international observatory community on Mauna Kea and works in a different wavelength range from optical telescopes.
