SkySafari 4: Journey into Night! Explore Sun, Moon, Mars, Stars, Satellites, and NASA space missions!

Age Level: Ages 8-12, Ages: 12 +

MACWORLD 2010 Best of Show Winner
Sky and Telescope Hot Product for 2012

This app is very cool! Like a lot of other night-sky apps, this one does show you the night sky in real-time, but more interestingly, allows you to zoom in and see even where the moons of the planets in this solar system are. We are talking 120,000 star clusters, nebulae and galaxies, including all of the major planets, moons and dozens of comets and satellites.

You can "look" at the night sky on planet Earth, from up to 100 years, past or future. There is built-in "motion" hardware that allows you to search for celestial objects and locate them. It even has a night vision mode, to eliminate stress on your eyes.

There is a vast amount of data included on history, mythology and data on specific objects. The photo section has some of the most beautiful shots I have ever seen of galaxies, nebulae, and the like. There are even photos of the NASA spacecraft.

You can stay up to date of the current celestial "scene" with the SkyWeek and Sy & Telescope features, which show you all the major events on a daily basis.

All of this and more, this app packs a big punch at only $2.99 (as of this review date). The casual star-gazer could not ask for more! There is also a Pro version for $39.99 that has a lot of additional features.

Compatible with iPhone, iPad, and iPod touch.
