Astronomy fascinates me. So Stellarium is my pick for freeware Friday. With Stellarium, you’re able to view the sky from any point in the world and at the same time overlay it with planets, constellations and galaxies. Want more information on an object, just click on it.
This makes Stellarium a great way to teach or a great way to just kill some time.
Stellarium is free open source software for Linux, Mac, and Windows. Interested. All the info is at its Download wiki
