What is Astronomy?
Astronomy is a natural science that deals with the study of celestial objects (such as moons, planets, stars, nebulae and galaxies); the physics, chemistry, and evolution of such objects; and phenomena that originate outside the atmosphere of earth (such as supernova, gamma ray bursts, and cosmic background radiation). A related but distinct subject, cosmology, is concerned with studying the universe as a whole.
Astronomy picture of the Day
Explanation: A single image from the world's most powerful survey instrument captured this spectacular skyview. Looking toward Sagittarius, the scene spans nearly 3 degrees or six times the width of the Full Moon. At bottom, upper right, and lower left it covers the Lagoon Nebula (M8), the Trifid Nebula (M20), and NGC 6559, in the crowded, dusty starfields of the central Milky Way
