What is astronomy?
Astronomy is often regarded as the oldest science, born out of our curiosity about the sky. Digital images of the beige planet, surrounded by beige and black rings, set against a pitch-black background. The study of space above the Earth's atmosphere is called astronomy. Named after a Greek astronomer, it studies stars, planets, comets, galaxies, and larger objects in the universe.
