Orion Nebula: Bright, ionized gas, young stars, active star formation.
description
The image is a photograph of the Orion Nebula, a large region of ionized hydrogen gas in the constellation of Orion. The nebula is located about 1,350 light-years from Earth and is one of the brightest and most-studied nebulae in the night sky. The nebula is home to a large number of young stars, which are responsible for the nebula's bright colors. The nebula is also a site of active star formation, and astronomers have observed a number of protoplanetary disks in the nebula.
