Beyond Arcturus

See this star map (right) large: "What's on Earth Tonight?".

This is a star map that shows how far the signals from U.S. television shows have travelled into space since they were first broadcast. The final episode of the original Star Trek has passed beyond the star Arcturus, about 37 light years from Earth.

Geography may not be all about maps, but maps are all about us.
Like, you've probably seen the famous map of the world "upside down"--with north at the bottom. There is no right-side-up in space.
I Iove the way the endlessly fascinating site Strange Maps, where I found this star map, shows us how subjective mapping is.
