Image Description and Details : NGC 1499 and IC 2005 combine to make up what is known as the California Nebula due to its long and narrow outline. About 1000 light years from Earth, this emission (primarily hydrogen alpha and beta) nebula is at least partially energized by the bright massive star above it in this image (Xi Persei with a total luminosity estimated at 263,000 times that of our sun).
