Star Chart is a free app in the Windows Store which allows you to explore the solar system.
We’ve modeled the swirling gas clouds on Saturn, Juptier, Neptune and Uranus. We allow you to remove the atmosphere on Venus, the Earth and even Titan to see the surface detail and seas beneath (Methane oceans on Titan!). We’ve even added twinkle to Earth’s night lights. And the list goes on and on… 😉 We’ve basically remastered the entire solar system and night sky (where data is available and some places used a bit of artistic license) and we’ve created what we believe to be the most amazingly detailed and visually stunning (free) astronomy app available anywhere on any platform. – San Shepherd, co-founder of Escapist Games
