KStars is a graphical desktop planetarium. It plots the positions of stars, constellations, star clusters, nebulae, galaxies and planets in the night sky for any date, from any location on Earth. The display can be panned and zoomed, and it can even identify and track objects as they move across the sky. KStars is highly configurable, you can control what objects are displayed, and with what colors. Images of any part of the sky can be downloaded from online databases. Our plan is to make KStars an interactive tool for learning about astronomy and the night sky.
