Description

The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. 

It is so named because it appears to resemble the outline of the US State of California on long exposure photographs - if you use your imagination. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually.  It lies at a distance of about 1,000 light years from Earth.

Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud by chance echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way's Orion Arm. 

Known as NGC 1499, the classic emission nebula is around 100 light-years long.  In this image, the most prominent glow of the California Nebula is the bright light characteristic of hydrogen atoms recombining with long lost electrons, stripped away (ionized) by energetic starlight. 

The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei just to the right of the nebula. 

A regular target for astrophotographers, the California Nebula can be spotted with a wide-field telescope under a dark sky toward the constellation of Perseus, not far from the Pleiades.
