About this site
This encyclopedia is based on astrobiology articles imported from Wikipedia. You are welcome to join in and help edit it. We welcome those knowledgeable in astrobiology especially, and your expertise and knowledge will be respected here. The aim here is to have a small friendly wiki, where we work together, and know each other. Do introduce yourself, here New editors

Other wikis
These wikis are also developed from Wikipedia pages originally:


 * Encyclopedia of Microtonality
 * Encyclopedia of Buddhism - set up by Dorje108 with me as co-admin.
 * Doomsday Debunked

For the background to why we set up new encyclopedias, instead of working on the pages in Wikipedia itself, see background to this encyclopedia. Also see my science blog post here:


 * Why It's Easy To Improve On Wikipedia In Specialist Encyclopedias (Ours Are For Astrobiology, Microtonal Music, And Buddhism)
