What the giant radio telescope at the observatory shows
The large dish stands beside a mountain observatory building and is aimed toward the sky. Its setting on a high plateau reflects the remote places where astronomers often position equipment used to study signals arriving from space.
Facts about radio astronomy in the mountains
Radio telescopes collect radio waves rather than visible light, so their dishes act more like enormous antennas than ordinary optical telescopes. Mountain plateaus can offer broad views of the sky and separation from cities, whose electronic equipment may cause radio interference. Several radio telescopes can also work together to make more precise observations.
