Description

The California Nebula is a large, and long nebula as far as deep-sky objects go. The California Nebula is 2.5° long (60 light-years across), and roughly 1,500 light-years away from Earth......This nebula’s signature reddish glow is thanks to the nearby star, Xi Persei, seen at the upper right side of my image. This luminous blue star known as Menkib is a blue giant that is over 12,000 times brighter than the sun. This massive star ionizes the hydrogen atoms in the California Nebula and is responsible for creating this deep sky object in our night sky.
