Do you want to know which celestial objects glitter in the night sky?

With the Star Safari 4 app, you can explore the sky while camping in the wilderness. This app shows you 120,000 stars, star clusters, nebulae, and galaxies in the sky. It also displays our Solar System’s major planets and moons using NASA spacecraft imagery, including the best-known asteroids and comets. Best of all, Sky Safari 4 includes a time simulation feature that allows you to track a star’s location and path at any time up to 100 years in the past or future.

SkySafari 4 comes with compass and gyroscope support. Just point your iPhone or iPad to the sky to identify the planet and stars pointed at that direction. New SkyWeek integration means that you can get a new SkyWeek’s interactive sky chart every single day. Night vision feature lets you explore the sky in the dark with less distractions, and the Time Flow feature lets you animate the night sky by adjusting the flow of time on your device. SkySafari 4 also includes a flurry of educational content, including hundreds of space images from NASA, Hubble Space Telescopes, and more. If you are wondering which stars populate the night sky, be sure to grab this app.
