Google Moon + Google Earth
1. Google Moon
< http://moon.google.com/ >
Google Maps, but with imagery of the Moon:
"In honor of the first manned Moon landing, which took place on July 20,
1969, we've added some NASA imagery to the Google Maps interface to help
you pay your own visit to our celestial neighbor"
If you zoom in close enough, you'll find out what the Moon is really made
of.
BTW, the Moon is in perigee today (July 21) - which means the Moon is at
its closest point in its orbit around the Earth (in the current cycle).

2. Google Earth
< http://earth.google.com/ >
or, Google Maps on steroids. It's a desktop app which takes Google Maps
to a new level. I've held off on featuring this because it's Windows-
only (currently).
