Astronomy Picture of the Day (APOD)  features a gas cloud known as a cometary globule. This one, known to astronomers is CG4, and is unusual in that its "head" has ruptured and the result is a menacing looking jawed creature.

The background for this image is brightly dotted with a variety of objects also includes, purely by chance, a galaxy that appears closer to these menacing jaws than it really is. 

Another spectacular image of the features "far out," about which an amazing amount is known through the investigations of scientists.
