Family Fridays at MoMath presented by Two Sigma:
"Sky Spectaculars: Now You See It, Now You Don't!"

Friday, May 15, at 6:30 pm EDT (New York)

Join Professor Jay Pasachoff, one of three people who have seen more total solar eclipses than anybody else in the world, for an evening celebrating the wonder and delight of observable events in our solar system.  What makes the sun disappear, and what's the best way to watch it when it does?  Why are some eclipses full and others partial, and what causes an annular (ring) eclipse?  When can we see the next partial and total eclipses in New York, and what other exciting things will be happening in our skies?  Professor Pasachoff, Chair of the International Astronomical Union's Working Group on Solar Eclipse and a professor at Williams College, takes us on an exciting journey of mathematical discovery, including a hands-on demonstration illustrating why solar and lunar eclipses occur just a few times each year.  Thanks to the generous support of Two Sigma, this program is free to attendees.

This is a live-streamed event.  Occasional video recordings are made available for a fee at
