I just recently read Galileo's Starry Messenger, which is just about to have its 400th birthday...so I'm psyched to tune in for this one tonight. See the teaser video below, and tune in at 10pm Pacific/Eastern, 9pm Central tonight (check local listings for specific airdate in your area, or visit www.400years.org).
400 Years of the Telescope, Tonight on PBS
Celebrate Galileo's Starry Messenger on its 400th birthday! Don't miss the teaser video and tune in tonight for a special event.
