About the website creator

The CD was created by L.Z. Han, a student in the USA who has a deep fascination with space and space science. She started researching constellations out of an interest in learning more about the universe and the objects it contains, and she used the directory as a means of sharing the knowledge she gained with the world. L.Z. Han wrote, coded, and designed all material presented on this website, with the exception of images.

L.Z. Han is also the developer of the Eagle Directory, a database that describes all known eagle species.
