The "Black Eye" Galaxy (M64)

 
According to The Hitchhiker’s Guide to the Galaxy, “Space is big. Really big. You just won’t believe how vastly hugely mindbogglingly big it is.”

That’s why we’ve always bookmarked this Java tutorial. With it, you can travel 10 million light years in 60 seconds — and so imagine just how spacious space is.

The tutorial will beam you 100 quintillion (1020) kilometers from Earth, to a place in space where the Milky Way galaxy is just one of many galaxies beckoning from a distance. Then, each click will take you an order of magnitude closer to home. But even traveling at that exponential speed, it will take you 15 clicks to see the beautiful Blue Marble again. And once you’re back on Earth, there is a microscopic universe to explore!
