Brahe and Kepler, along with Sir Isaac Newton and Galileo Galilei, were giants who replaced the medieval view of the world with a modern one, said Kaare Lund Rasmussen, lead author of the Brahe ...
The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s.
