Aciqra (uh-SEE-kruh) is a free and open source virtual sky map and planetarium which tracks and displays astronomical bodies including planets, nebulae and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It's software that generates a virtual sky so you'll always know exactly what's up in the real one. More...
