Exploring the vast expanse of interstellar space and distant worlds
Since the discovery of the first exoplanet in 1992, astronomers have identified thousands of planets orbiting stars beyond our solar system. These distant worlds come in various sizes, from rocky super-Earths to gas giants larger than Jupiter, and exist in environments ranging from scorching hot to freezing cold.
