In the astronomical community of the future, there are many types of astronomical telescopes.
According to technical principles, they can be divided into many models:
For example, reflecting telescopes, refracting telescopes, radio telescopes, etc.
The first astronomical telescope in human history, made by Galileo, was a very standard refracting telescope.
The modern Hubble Telescope is also a refracting telescope, although its diameter has reached the human manufacturing limit of a single optical mirror.
Telescopes like the James Webb Space Telescope are reflecting telescopes.
As for radio telescopes, they are much less common.
For instance, the giant radio telescope in our local mountainous region is a radio telescope, and the ticket is only fifty yuan.
As for the astronomical telescope Xu Yun mentioned, it naturally refers to the reflecting telescope, which is the most manually constructed telescope in the future.
