Comparison Of Different Telescopes: James Webb Space, Giant Magellan and Event Horizon

Mankind's obsession with space and the persistence of searching for extraterrestrial life has led to the invention of telescopes as a way to explore the mysterious vastness of the universe. In this paper, the development history of the telescope is studied, as well as the famous events observed by the telescope (black hole, solar structure, etc.), and the structure, environment and interference of the ground-based telescope, space telescope and joint telescope are compared and analyzed. By comparison, it is found that most large telescopes have a variety of research directions and are more restricted, and even if the relevant research part is strengthened, it will still be affected by the inevitable, depending on their geographical location and observation method. After analyzing and comparing different telescopes, the purpose, structure and how to avoid shortcomings of each telescope can be more clearly defined, so as to play a reference role in the future development of telescopes.
