What is the City of Astronomy?

Our city, Pasadena, is the City of Astronomy! Pasadena has been a special place for astronomy for more than 100 years. Many significant discoveries in Astronomy, including magnetic fields in sunspots, the expansion of the universe, the first quasar, the detection of gravitational waves, and the first evidence of dark matter, have been made by Pasadena astronomers or astronomers using facilities enabled by the City of Astronomy. With its rich history in astronomy, Pasadena has become a nurturing ground for innovations and has produced a series of cutting-edge discoveries.

Where is the City of Astronomy?

Pasadena is located in California, the United States, the Earth, the Solar System, and the Milky Way Galaxy.

How do you celebrate the City of Astronomy?

Since 2016, scientists from around Pasadena have gotten together to host public education events to showcase the special role Pasadena has played in the discovery and development of space science over the last century. Hopefully you’ll be able to join us for a future series of outreach events!
