Over 400 years ago, Galileo discovered the stars using his now-famous astronomical telescope. Centuries later, you can discover the wonders of astronomy with these telescope from the Museum.

The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first telescopes being made. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. The word telescope now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.
