CyberSky is a colorful, easy-to-use program that transforms your computer screen into a planetarium, allowing you to learn about astronomy by exploring the sky in the past, present, and future. CyberSky duplicates the features of a traditional planetarium on your computer screen. It provides a way for you to learn the names and locations of the constellations and stars, and to become familiar with the motions of the sun, moon, and planets across the sky.

Version 3.3 supports Windows XP visual styles. The traditional-style toolbars have been replaced with modern-style flat toolbars with grippers. Several small memory leaks have been corrected.
