Wrapping It Up
Imagine the night sky as a piece of black paper that is wrapped around the Earth.
The seam of the paper (where the edges are taped together) is at 180o.
The Crab Nebula would be close to the seam
since it is close to 180o. Imagine someone pulling the tape off and
laying the paper flat on a table. Now where would the Crab be? It would be near
the right side of the paper, just as it is on the black and white map!
The black and white map tries to show all parts of the
universe on a flat screen.
