Molonglo Observatory Synthesis Telescope

The Molonglo Observatory Synthesis Telescope consists of two cylindrical paraboloid structures measuring 778 meters long and 12 meters wide, aligned in an east-west direction across the landscape. The facility captures radio signals from space using thousands of small antenna elements integrated into its design.

Construction of the original prototype began in 1960 under the direction of Professor Bernard Y. Mills and became operational in 1967. The instrument was pioneering in its design and contributed significantly to the development of radio astronomy techniques.

The site takes its name from the nearby Molonglo River, which marks its location in the region. The observatory attracts researchers from multiple institutions studying the southern sky.

The site is located in a remote, flat area chosen to minimize radio interference from nearby electronic sources. Visitors should note that this is an active research facility where access may be restricted to certain areas.

The facility allows researchers to determine distances to fast radio bursts more precisely than single-dish telescopes can achieve. This capability makes the instrument particularly valuable for understanding these mysterious cosmic events.
