Comment |
North is to the right.
The colors of this
image more closely follow the Hubble Palette. The presence of
sulfur, hydrogen and oxygen are more clearly shown. Red indicates
the presence sulfur, green hydrogen and blue oxygen. With no
color manipulation, the image would be basically green, due to the
dominance of hydrogen.
There are a lot of objects in this image. Place your mouse
over the image to see labels of the objects.
