NGC1499
California Nebula
The
California Nebula is an emission nebula located about 1,000 light-years
from Earth. It stretches over 40 light-years in length, and owes its
reddish glow to the Ha and Hb gases in the nebula, excited by
nearby star Xi Perseus, the bright star to the right. North
is to the left.
