The Local Arm. Map of the Local or Orion spiral arm of our Milky Way galaxy,which stretches from the constellation of Cygnus (left) to Vela. The Sun is in the small yellow bubble at centre right. White circles with blue cores are star clusters; pink areas are clouds of ionised hydrogen; clouds of neutral hydrogen are yellow and molecular clouds are orange. Pale blue areas are groups of hot,young stars. Planetary nebulae are purple ellipses. The Gum Nebula (pink ring,centre right) is a huge bubble (800 light years across) inflated by a succession of supernova explosions. The Henbest/Baum galaxy map is based on the location of 1500 bright stars,nebulae and other objects | |
