The site design is somewhat unfortunate, but The Virtual Cave features lots of photos and information on, well, caves and cave formations. We've all heard of stalagmites and stalactites, but I'd never heard of cave draperies or cave pearls before. Then you've got your helictites, your aragonite, and your splash stalactites (found in lava tubes). And they've got a Show Caves Directory of caves in the United States that are open to the public, with addresses and contact information by state.

The winners of the 2005 Nikon Small World Competition are up (previous years going back to 1977 are also worth a look). Photomicrography produces some amazing imagery, giving us glimpses into both the inner workings of living things, and the intricate structure of nonliving things (just click "find all").

The most detailed map of Mars ever produced. Brought to you by Malin Space Science Systems. The images were captured from The Mars Global Surveyor. They really are incredibly clear. I'm trying find the Mars Face. No luck yet though. (Click image to zoom in)
