SkySafari isn't just an award-winning iPhone astronomy app any more. SkySafari's interface has been redesigned from scratch for the Mac, using 100% native Cocoa OS X controls. SkySafari's iOS OpenGL astronomy engine soars on the Mac, and a full-sized monitor, mouse, and keyboard open up a universe of new possibilities.
Like the SkySafari iPhone apps, SkySafari for Mac OS X comes in three versions. This is the basic version. It shows you 46,000 stars, plus 220 of the best-known star clusters, nebulae, and galaxies in the sky. It displays the Solar System's major planets and moons using NASA spacecraft imagery, and includes the best-known asteroids and comets.
SkySafari accurately shows you the sky from any place on Earth, at any time up to one million years in the past or future. It includes encyclopedic descriptions of the constellations, stars, and planets written by professional astronomers.
