History

The galactic emission nebula NGC 1499 was discovered on 3 November 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]
