Comment |
North is to the bottom
This is a close up
view of an interesting region in IC1848, the Soul Nebula. IC1848 (Sharpless
2-199, LBN 667) is locate in the constellation Cassiopeia, at a
distance of about 7000 light-years. The central formation is
reminiscent of Thor's Hammer in Bryce Canyon, Utah.
This image, captured
with a hydrogen-alpha filter, shows the extent of the hydrogen gas. |
