The California Nebula (NGC 1499) is a large emission nebula and star-forming cloud of around 100 light-years long, located some 1,000-1,500 light-years away in the Orion spiral arm of the Milky Way galaxy (where our Solar System is also located) in the constellation of Perseus, what makes it one of the nearest H II regions to Earth. It is so named because it appears to resemble the outline of the US State of California. It has a very low surface brightness and it’s very difficult to observe visually.
