- This easy to use software, the WorldWide Telescope will help you explore space by combining images from space-based telescopes and from those on the ground. The planetarium comes with both the Web Client and Windows Client to help you get a clear glimpse of the sky.
- Introduction Astronomy Software is a pretty broad spectrum, providing everything from simple mapping software (relative positions of the solar system), through detailed observation planning software to first-person planetarium software. I looked at several free astronomy programs for producing sky maps and didn't pick a best as I couldn't decide among the three contenders for the top spot.
- Cosmic Watch: Time and Space. Platform: iOS/Android Price: $4.49. Cosmic Watch is an AR-assisted 3D planetarium that allows you to explore and study stars, constellation, and the entire solar system. The app comes with a clock, using which you can go back in time (on in the future) to understand how time affects the location of astronomical.
