Google Sky Map Time Travel Option

Install Google Sky Maps for Android, tap the settings button on your phone, select the time travel button (with an icon very familiar to fans of the old “Time Tunnel” TV show), and check out what the night sky looked like in the past or will look like in the future. That’s what the Google Sky Map 1.6 update gives you.
