It's a good idea to take a step back once and a while and marvel at this great universe that we are all a part of.
The Horsehead Nebula is probably one of the most popular sites in the night sky, but it never ceases to amaze.

The famous Horsehead Nebula in Orion is not alone. A deep exposure shows that the dark familiar shaped indentation, visible just below center, is part of a vast complex of absorbing dust and glowing gas. To bring out details of the Horsehead's pasture, amateur astronomers at the Star Shadow Remote Observatory in New Mexico, USA fixed a small telescope on the region for over seven hours filtering out all but a very specific color of red light emitted by hydrogen. They then added the image to a full color frame taken over three hours. The resulting spectacular picture details an intricate tapestry of gaseous wisps and dust-laden filaments that were created and sculpted over eons by stellar winds and ancient supernovas. The Horsehead Nebula lies 1,500 light years distant towards the constellation of Orion. Two stars from the Orion's Belt can be found in the above image.
When you consider the incredible speeds at which the stars and gases are moving, and that the Horsehead has held it's shape for millions of years, the sizes and distances become almost impossible to imagine.
