Outer space is big. From our vantage point, it’s mostly just dots in the sky that we see at night. But there are billions of stars, asteroids, comets, and planets out there. You can see of them when you look up on a clear night, more if you use a telescope, and more still if you use SkySafari, an app that shows 46,000 stars and many of the best-known galaxies and nebulae with images from NASA and other expert star-gazers.
SkySafari isn’t the prettiest app around, but it more than makes up for it with the majesty of the stars and reams of encyclopedic information. It’s deep enough that serious astronomers can use it as a reference tool, and suitable for the rest of us to explore and learn about outer space.
