SkySafari 4 is the award-winning astronomy app now available on Mac OS X! Originally developed for iOS, SkySafari 4 has been rebuilt from the ground up for Mac OS X, using 100% native Cocoa OS X controls. SkySafari's OpenGL astronomy engine soars on the Mac, and a full-sized monitor, mouse, and keyboard open up a universe of new possibilities.

If you're new to SkySafari, this is the Basic version. It includes everything you need to get started learning the night sky: 120,000 stars; over 200 star clusters, nebulae, and galaxies; all major planets and moons, and dozens of asteroids, comets, and satellites - including the ISS.

Here's what you can do with SkySafari 4:

Explore the night sky from anywhere on planet Earth, up to 100 years in the past or future. Animate transits, conjunctions, eclipses, and other events with SkySafari's Time controls. Preserve your eyesight with Night Vision mode. Learn the history, mythology, and science of the heavens from SkySafari's huge library of in-depth object descriptions. Browse hundreds of astronomical photographs and NASA spacecraft images.

SkySafari takes advantage of Apple's latest Mac OS X features. It understands multitouch gestures and supports full-screen mode. Its responsive, fluid interface borrows from the award winning SkySafari for iOS. SkySafari for Mac OS X truly brings astronomy software into the 21st century. It's more than just a star chart - it's your celestial travel guide!

All this is built into SkySafari 4 - you don't need an internet connection to use it. The more advanced versions, SkySafari 4 Plus and Pro add even more features and data, including the ability to control your telescope! - but this Basic version has everything the casual stargazer will ever want. (Please note: due to Apple policy, there is no discount upgrade path to SkySafari 4 Plus or Pro.)

If you've used SkySafari before, here's what's new in version 4:

  • Apple Maps integration: choose your location from a built-in Maps view.
  • Animated meteor showers, with complete viewing information and spectacular graphics.
  • New horizon panoramas: Yerba Buena Gardens in downtown San Francisco, Uluru (Ayers Rock) Australia, and the top of Mauna Kea on Hawaii's Big Island. Or add your own!
  • New and updated descriptions for hundreds of objects.
  • Dozens more tweaks, bug fixes, and additions we don't have room to list here!

  • What's New
    1) Fixes incompatibility with Mac OS X 10.6.8 thru 10.8.x.
