Description

This object is a bright molecular cloud located 1400 light years away in the constellation of Andromeda. The cloud, known both as LBN 534 and GAL 110-13, stretches for 1.5 degrees (3 times the apparent width of our full moon) across the image. A small bluish star-like planetary nebula (PK 110-12-1) is seen on the left side of the image, just below the center.

One of my favorite parts of this image is the unique faint small dark oval spot in the cloud near the center of the image. I also find it interesting that the area immediately around the bright cloud is darker than any of the other background in this region.

The sky in this region is filled with bright colorful stars. These stars are somewhat obscured by the extensive dust in many parts of the image. The three bright blue stars in the lower left of this image are believed to be responsible for illuminating this molecular cloud. The three stars are moving in the same direction and are at the same distance from us as the cloud. The top left star of this grouping is responsible for illuminating a blue reflection nebula known as vdB 158. This nebula is the brightest of many small reflection nebulae seen in this image.
