To study outer space in greater detail through magnification.
Astronomers have used telescopes and charge coupled devices.
Telescopes are instruments used by astronomers. The first person to do this was Galileo.

Telescopes
Telescopes are commonly used by astronomers to observe objects in space such as planets, stars, and galaxies. Microscopes are not typically used by astronomers as they are designed for studying very small objects on Earth, such as cells and microbes.
Telescopes are used by astronomers to collect light from celestial objects such as stars, planets, and galaxies. They enable astronomers to study these objects in detail, revealing information about their properties, composition, and motion. Telescopes can also help astronomers in detecting and studying phenomena like supernovae, black holes, and exoplanets.
The telescope wasn't invented until about 1604, so "early" astronomers had no telescopes.

TELESCOPES
Astronomers use telescopes to study stars and planets by capturing light from these celestial objects and analyzing it. They can gather data on the properties of stars and planets, such as their temperature, composition, and distance from Earth, to deepen our understanding of the universe. Telescopes come in various forms, such as optical telescopes, radio telescopes, and space telescopes like the Hubble Space Telescope.
Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.
