Astronomy Picture of the Day is a site that consistently provides some of the best pictures of the marvels of our universe. Each day a new picture showing an image of the world and the planets and stars above us is presented.
An example is this picture showing two spiral galaxies that will slowly collide over the next billion or so years.
Perhaps some distant relative of humanity will be around to record the 'cosmic wreck'.
Other pictures share images of planet Earth and our interactions with our neighbors, near and far, in our solar system, galaxy, and beyond.
