A fast professional astronomy planetarium and star mapping program. It displays star positions of any instance of the day observed from any geographic location on Earth. The star positions can be viewed and presented as images of semispherical whole sky or any of the user-defined sub-areas. These images can be zoomed at different scales, rotated, screen-captured, and printed. Also, StarCalc has many other functions of calculation and showing of sky objects.
"Extra efficient algorithms allow the program to calculate a sky image in a fraction of a second even just on very old computers. StarCalc has a simple interface, most operations are implemented by mouse. The program employs the WYSIWYG technology, which helps you print a detailed image of any enlarged area of the sky in its finest astronomical details."
A real-time 3D space simulation that lets you travel through our solar system and to over 100,000 stars in our neighborhood. "Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy. All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit. Celestia is expandable. Celestia comes with a large catalog of stars, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy-to-install add-ons with more objects."
The program's only drawback is its system requirements, which are fairly high: on a computer with less than 64 MB RAM, the images appear with a noticeable computer slowdown; but if you happen to have a Pentium III 700, 128 MB RAM with a 3D video card and OpenGL drivers, Celestia works like charm.
