I have something to share with you.

Have you ever been outside with your child on a perfectly clear night and they ask you to show them the Big Dipper and other constellations?  I have and hate to admit that I had to defer to my 20 something cousins on a recent trip to Mexico.  Not only did they show my daughter the Big Dipper, but they showed her Mars and Saturn.  And then they pulled out their phones and opened SkyView.

Wow.  Spending on where you point your phone, it shows you everything.  All the planets, the constellations AND even the international space station.  And you can even use it during the day to see where the moon and the other planets are during that time.  Now I can show my daughter the planets and the constellations without going back to school!
