Google Earth Turn Up The Lights

www.google.com/earth/

Google has rolled out some spectacular new layers for Google Earth. “Astronaut Photography of Earth” is filled with images from the last 40 years of NASA Earth exploration, and “Earth City Lights” has stunning views of our home planet at night, as viewed from space.

The new layers can be found in the Featured Layers section of Google Earth. If you don't have Google's desktop atlas program, it's available as a free download . If you already have Google Earth, there’s no need to upgrade your installation. The layers should be there -- just look for the "NASA" header.
