Found between Cygnus and Cassiopeia, this beautiful nebula is nearly 15 light-years wide, located some 4,000 light years away. Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars. The dusty halo around the fringe of the nebula is a dark molecular cloud, which gives the surroundings a bit of a washed out appearance. In wide field exposures, you can see a dark dust lane running away from the nebula, which would be
towards the top of the image.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
