What is the main purpose of the Hubble Space Telescope?
The Hubble Space Telescope's main purpose is to observe the universe in visible, ultraviolet, and near-infrared light, providing unprecedented views of distant galaxies, nebulae, and other celestial phenomena.
What is the Kuiper Belt, and what is found there?
The Kuiper Belt is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at about 30 AU to approximately 50 AU from the Sun. It is home to numerous small icy bodies, including dwarf planets like Pluto.
