Q

What are radio telescopes?

A
  • Unlike optical telescopes, radio telescopes can detect invisible gas and, therefore, they can reveal areas of space that may be obscured by cosmic dust.
  • The first radio signals were detected by physicist Karl Jansky in the 1930s.
  • The Arecibo telescope in Puerto Rico, which was the second-largest single-dish radio telescope in the world, collapsed in December 2020. The telescope was built in 1963.
