Hail, Osiris*

"Visible to the unaided eye, the Great Orion Nebula appears as a small fuzzy patch in the constellation of Orion. Long exposure, digitally sharpened images like this one, however, show the Orion Nebula to be a busy neighborhood of young stars, hot gas, and dark dust. The power behind much of the Orion Nebula is the Trapezium -- four of the brightest stars in the nebula. Many of the filamentary structures visible are actually shock waves - fronts where fast moving material encounters slow moving gas."

Like the last post, this one came from the APOD archive.

* "...Osiris in his stellar form is the constellation of Orion."
