AI overview
Astronomy is the scientific study of celestial objects and phenomena in space, such as stars, galaxies, and the centers of galaxies. It matters because it helps us understand the universe and our place in it, using advanced instruments like those at major observatories to observe and investigate distant cosmic objects.

Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is the branch of astronomy that studies the universe as a whole.
