Doors open at 6:30 PM. At 7:00 PM we'll begin our lecture from R.P. Hale, Senior Educator at the Discovery Center as well as an archaeoastronomer and solar astronomer. Mesoamericans devised a number system over 3,500 years ago, using but three symbols for the zero, one and five--and they counted by twenty instead of by tens. Two thousand years ago, the rising Mayan cultures adapted the numbers, existing calendar systems and astronomy, to build the most complicated calendar system in human history. The Mayan calendar system is also never-ending and the most far-reaching: one calendar "wheel" extends over 72 octillian years (that's 72 followed by 27 zeros!), long predating the Big Bang and long postdating the end of our universe!
Archaeoastronomer and solar astronomer R.P. Hale will explore these Mayan numbers and calendar wheels and how they are directly tied to astronomy. The audience themselves will participate by finding and identifying Mayan dates from his actual artifact photos, then go through the process of converting those Mayan dates into our own calendar.
At 8:00 PM in the Planetarium, join us for a Tonight's Sky showing. Learn about the constellations, planets, and more visible in the night sky in addition to the spectacular super blue moon that happened on January 31.
Doors close at 9:30 PM.
The all-inclusive price for Super Stellar Friday at the Discovery Center is $11.50 for adults, $10.50 for students and seniors, $8.50 for children 12 and under, and free for members. Pending clear skies, our observatory will be open and members of the NH Astronomical Society will be outside the Discovery Center with telescopes pointed to the sky, ready to share their knowledge and views from their telescopes for free.
