Algonquin 46m radio telescope

The Algonquin 46m radio telescope is a large parabolic antenna located in an observatory within Algonquin Provincial Park. The installation consists of a concrete foundation and rotating steel structure that allows the instrument to scan the sky in different directions.

The telescope was completed in 1966 by Canada's National Research Council as part of the Algonquin Radio Observatory complex. It played a role in early experiments that demonstrated international collaboration in radio astronomy.

The telescope marked a milestone in Canadian astronomy by conducting the first successful very long baseline interferometry experiment targeting the quasar 3C 273.

The telescope can be viewed from outside during open hours, with the park grounds surrounding the facility accessible on foot. Visitors should be prepared for unpredictable weather and bring appropriate clothing.

The observatory was the site of a groundbreaking experiment where radio telescopes on different continents were coordinated to observe extremely distant objects. This technique helped astronomers see details that would be impossible with a single telescope.
