Challenge has finished
Photography is more than just an art form; rather it also has great importance in science, industry, and government. Submit a photograph that has scientific or technological importance: consider astrophotography, photomicrography, or other photos with scientific, industrial, or technological interest. Just because a photograph has scientific interest, that does not mean that it must not be a striking and memorable image in its own right.

This image of the Whirlpool Galaxy (Messier Object 51) was taken with a Canon XT tracking through a 10" telescope. This is actually a pair of Galaxies interacting with each other, giving the strong spiral appearance. The light traveled 37 million years to reach the camera.
