SkySafari 1.7.3

SkySafari isn't just an award-winning iPhone astronomy app - it's now available for Mac OS X! 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. 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. And it contains hundreds of images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.

SkySafari has a "Night" button to preserve your dark adaptation as you're exploring the night sky. The Time Flow feature lets you animate the night sky using simple VCR controls - follow the motion of the stars and planets as SkySafari compresses days, months, and years into a few seconds.

SkySafari takes advantage of Apple's latest Mac OS X features. It understands multitouch gestures on Macs with multitouch trackpads, and supports OS X 10.7 (Lion) full-screen mode. And its responsive, fluid interface borrows from the best aspects of SkySafari for iPhone. SkySafari for Mac OS X truly brings astronomy software into the 21st century. It's more than just a star chart - it's a celestial travel guide!
