Do you remember the thrill you experienced the first time you saw Jupiter or Saturn through a telescope? If so, Gas Giants is a must for your iOS library!

Gas Giants lets you peer through a simulated telescope to observe Jupiter, Saturn, Uranus, and Neptune and their major moons, as they appear right now, or at any date and time.

Amateur astronomers, teachers, scout leaders, astronomy club members or anyone who uses a telescope or binoculars to view the night sky will love Gas Giants.

Gas Giants requires an iPhone 3GS or later, or an iPod Touch 3rd Generation or later (specifically, OpenGL ES 2.0 or later) to run. All iPad models are supported.

Nails it

Can you see Jupiter's red spot? Which moon is Titan? I used to look this info up but this app makes it all faster and does it so well that it has earned it's place on my in my Astronomy collection. My only minor nit is that if you want to get the positions for more than a day in the future it's a pain - you have to change the app settings. Why not just put this functionality in the rolling time control with a go to now button?

Wonderful program!!!!!

With this program, I can easily and quickly determine when the Jovian moons and their shadows will pass in front of Jupiter. This is a great help for me. Also, when looking at Saturn, I can identify it's moons as well. I have never been able to do that.

You can set the time and date to view any 24 hour period

Gives you knowledge of what you are looking at

You no longer have to guess if that tiny white spot is a moon of Jupiter. This app made it all easy and comes with an EXTENSIVE amount of simulated telescopes to see what your view of the planet will be. Before buying a new telescope or lens, you can see how the gas giants will look like through your new accessory.
