History

The galactic emission nebula NGC 1499 was discovered on November 3, 1885 by American astronomer Edward Emerson Barnard. It received the nickname because it is similar in shape to the US state of California. [196]

Physical Properties

With a surface area of around 2.5 ° x 1 °, the nebula is very large, but has a low surface brightness. It glows mainly in the red lines Hα (656 nm) and Hβ (486 nm). The nearby, high-energy O7 star ξ Persei (Menkib), located at a distance of about 420 pc to 486 pc (1370 to 1585 light years), is held responsible for this. [145, 196]
