Explore the cosmos with Edward Herrick-Gleason, Director of the Southworth Planetarium . We’ll find much to engage us: from the moon phases to the complex planetary motions to the formation of galaxies. Along the way we’ll discover that the celestial realm and terrestrial world are inextricably linked, for the former gave rise to the latter and, of course, to us, as well.
