Mount Palomar Observatory

Mount Palomar Observatory, located in California, is a major astronomical research facility home to some of the world's largest telescopes. Its most famous instrument, the Hale Telescope, has a 200-inch (5-meter) mirror, enabling scientists to study distant galaxies, stars, and planets with great detail. The observatory has contributed significantly to our understanding of the universe, including discoveries about black holes, cosmic expansion, and planetary systems. Perched on a mountain to avoid city light pollution, it provides clear, dark skies ideal for astronomical observations, making it a vital site for advancing space and science exploration.
