Telescope is used to see very distant objects

Answer 2

An ancient instrument called a quadrant used spherical trigonometry to measure the altitude of a star in relation to the horizon. The armillary sphere, comprised of metal rings and using the zodiac, allowed for observation of the sky and demonstrated the movement of the stars. The astrolabe represented a multifunctional device that calculated the positions of the Sun and bright stars, and also worked as a kind of clock to tell time. Over the centuries, various cultures made star charts either to categorize stellar groups or to catalog the magnitude of stars. Astronomers also made broadsides, sheets of paper informing people about eclipses and other celestial phenomena.
