Study the ever-changing face of the Moon, watch the steady march of the planets against the stars, witness the thrill of a meteor shower, or the memory of a once-in-a-generation comet. The sights in our Solar System are dynamic reminders of our planet's position as part of a larger neighborhood. Study the ever-changing face of the Moon, watch the steady march of the planets against the stars, witness the thrill of a meteor shower, or the memory of a once-in-a-generation comet. In a few short generations, scientists have taken us from wondering about the nature of the Solar System to exploring every corner of it with advanced robotic probes, and inexpensive but powerful telescopes have become ubiquitous, allowing all of us to follow in the footsteps of Galileo as explorers.
