astronomical telescopes

Astronomical telescopes are tools designed to observe distant objects in space, like stars, planets, and galaxies. They work by collecting and magnifying light through lenses or mirrors, making faint objects appear brighter and clearer. There are different types: refracting telescopes use lenses, while reflecting telescopes use mirrors. Modern telescopes can be placed on Earth or in space to avoid Earth's atmosphere, which can distort observations. They enable scientists to study the universe's size, composition, and history, expanding our understanding of the cosmos.
