What is the origin of Hubble telescope?
The concept of space telescope first appeared in the seventies and eighties of 1940 and 19. NASA cooperated with the European Space Agency to design and build a space telescope. 1990, the world's first space telescope came out, and the designer named it after American astronomer edwin powell hubble (1889 ~ 1953).
1On April 22, 990, the space shuttle Discovery put the Hubble telescope into Earth orbit. The Hubble telescope began to run at an altitude of 600 kilometers above the ground, getting rid of the interference of the earth's atmosphere on astronomical observation, so its power far exceeded that of ground-based optical telescopes. The total weight of Hubble telescope is about 1 1 ton, the focal length is 57.6 meters, and the resolution is 0.005, which is 0/00 times of that of large ground telescope. The observation wavelength ranges from ultraviolet 120 nm to infrared 1200 nm, and the cost is1500 million USD. With the help of Hubble telescope, human beings have deepened their understanding of the formation of galaxies, roughly determined the age of the birth of the universe, increased their understanding of the evolution of stars, found evidence of the existence of black holes, and explored the structure of the universe through the study of distant quasars.
