NGC 1499 - The California Nebula. So called because of the loose resemblance to the outline of the state of California. This cloud of hydrogen gas lies about 1,800 light years away and is located within the same spur of the Orion spiral arm of the Milky Way galaxy as Earth. The hydrogen gas cloud is being illuminated by the star Xi Persei - the bright star at the top of the image. This single blue-white super giant star has an apparent luminosity of 13,500 suns and is approximately 40 times the mass of our sun. Its temperature is also extremely high - six times hotter than the sun (~66,000 degrees Fahrenheit). Being so massive, the star is destined to go supernova at some point in the next million years or so. It is one of the hottest and most massive stars visible to the naked eye.
