If the Moon Were Only 1 Pixel – A tediously accurate map of the solar system
Neat! My favorite way to show the impossibly large scale of our universe: <a href="http://spaceengine.org/" rel="nofollow">http://spaceengine.org/</a>. Set your speed to 10 light years <i>per second</i> and watch the Andromeda galaxy just sit there.<p>Also fun to see how slow even the speed of light is. Start at the sun and head for earth. Once you reach Earth marvel at how fast you had been going.<p>Head towards Jupiter and, once again, marvel at how impossibly slow your going compared to even the nearest background stars.
