The City of Astronomy - Pasadena

Pasadena has a rich history of astronomy discoveries, from the exploration of planets at NASA's Jet Propulsion Laboratory (JPL), to the discovery of the universe's expansion at Mount Wilson Observatory, to determining the extragalactic distance scale of the universe at Carnegie Observatories. This year, 10 Pasadena-based scientific institutions and organizations have partnered to celebrate Pasadena as the "City of Astronomy" during Pasadena's first Astronomy Week from October 16–22.
