Space telescopes are powerful instruments placed in orbit around Earth or other celestial bodies to observe the universe. Unlike ground-based telescopes, they avoid atmospheric distortion, allowing for clearer images of distant stars, galaxies, and other astronomical phenomena. Notable examples include the Hubble Space Telescope and the James Webb Space Telescope. These telescopes collect data across various wavelengths, including visible light, infrared, and ultraviolet. This capability enables scientists to study the formation of stars, the composition of planets, and the expansion of the universe. Their discoveries have significantly advanced our understanding of the cosmos.
