Online Class for Kids and Adults

Pluto has not been a planet since 2006. But this tiny world still inspires people of all ages while sparking controversy. In this delightfully witty class (based on his brand new book), astronomer Dean Regas teaches you how to educate your grown-up about the cutting-edge science of space, most crucially the reason why Pluto is NOT a planet anymore.

Great for all ages!

Tickets: $10 per household
