To use the Earth and Moon Viewer, you need a graphical Web browser with forms support and the ability to display GIF and JPEG images. In order to pan around the map or globe by clicking within the image, your browser must support "Client-Side Image Maps"—if you don't know what this means, don't worry: if your browser doesn't support the feature, you'll see a page which explains how to proceed.

Windows users can create images like this in real time, on their own machines, as well as view the sky, stars at the horizon, the solar system, orbits of asteroids and comets, and more with Home Planet, my public domain Earth/Space/Sky simulator available for your downloading pleasure. Other public domain astronomy and space software available from the same site includes:
