Pretty Pictures and Web Toys

This is "The Supernova Remnant Cas A, as imaged in X-rays using the ACIS camera on the Chandra satellite (Credit: NASA/CXC/SAO). The colours are red: 0.3-1.55 keV; green: 1.55-3.34keV; and blue 3.34-10.0 keV." It's from a Princeton collection of pretty astronomical pictures. My other favorite is this Owl Nebula, with lots of other cute little galaxies in the background.

My father also sent along this interactive map of Rome c. 100 C.E., which comes with or without text labels (in English or French). The possibilities for role-playing games, etc., just get better and better. I suppose teachers might find them useful, too.
