Ground-based telescopes are large optical instruments located on Earth that collect and magnify light from celestial objects. They are used to observe stars, planets, and galaxies, providing valuable data for astronomers. These telescopes can be equipped with various instruments, such as cameras and spectrographs, to analyze the light and gather information about the universe. The effectiveness of ground-based telescopes can be affected by atmospheric conditions, such as clouds and light pollution. To mitigate these issues, many observatories are situated in remote locations, like Mauna Kea in Hawaii or Atacama Desert in Chile, where the atmosphere is clearer and less polluted.
