Power Age Sky Simulator - Full featured planetarium software.

But it's soooo cool I don't want to! Power Age is a full featured planetarium software which gives the possibility to explore the sky from any point on the Earth at any given time. It operates with a vast number of objects: the biggest planets, comets, asteroids, 19 million stars, 14 000 deep sky object (from the best NGC/IC edition ever made). Power Age has almost completely customizable appearance and easy to use interface.

This is just too cool.
