- The "Professor Astronomy" logo was inspired heavily by the
"Bad Astronomy" logo of Phil Plait, http://www.badastronomy.com.
The font was obtained from FontFreak, and is the "Fedora"
font contributed by the ShyFonts Type Foundry. The image is a Hubble
Space Telescope image of Abell
2218, a cluster of galaxies lensing several background galaxies.
- The image of Saturn used in bulleted lists is
from the Voyager 2 spaceprobe and comes courtesey NASA/JPL-Caltech.
