Astronomy guide, Star Walk, shows stars, constelleations, satellites, and the like in the correct positions in the sky. Just hold your iOS device up to the sky, any time of day, and you’ll see what’s out there. This new update brings new additions to the astronomical data, optimization for the iPad mini, and a special visit from Kris Kringle himself. There’s even a contest with an iPad mini prize to enter, so get to it!

The latest update includes new additions to Star Walk’s night sky. Complete information as well as detailed 3D models of satellites are available for GLAST, Ajisai, COROT, Genesis I and Genesis II, INTEGRAL, and GPS Group, and others. Major internal optimization reduced the size of the app by half and allowed it to work and look stunningly on the iPad mini.

A special holiday surprise from Star Walk developers awaits for stargazers on December 21st when Santa will appear on the night sky on his yearly journey over the world.
