Join Altadena Stargazing Night on May 1 for guided stargazing with telescopes, all completely free and open to the public.

Astronomers and telescopes will be present to provide attendees with a guided view of the sky, featuring views of Jupiter, Mars, the Moon, as well as galaxies, star clusters, and nebulae. Professional astronomers will be on hand to answer your questions about astronomy, physics, and space. There will also be NASA swag available to take home, including images from the Hubble Space Telescope.

This event will take place at Gwinn Park, a small park on Orange Grove in east Pasadena, near Victory Park and the Eaton Wash. Because this is a residential neighborhood, attendees are asked to be mindful of their noise level while attending. Street parking is available on the adjacent streets around the park. The Stargazing Welcome Area with NASA swag and more information will be in the southeast corner of Gwinn Park. Notably, this location is outside the Eaton Fire mandatory evacuation area and burn scar, so it is believed that it should be reasonably free of post-fire toxins. Do not bring bright flashlights, but instead rely on the ambient red lights to preserve your night vision and to guide you to the Welcome Area and the telescopes.

This stargazing evening is totally free and open to all of the public. No reservations are necessary, just show up. There is no formal program, so drop by any time between 8:00 pm and 10:00 pm. Stargazing is not possible with cloudy skies. Check back the day of to confirm that there is clear enough weather to operate the telescopes, otherwise the event will be postponed to another day.

This event is staffed and co-sponsored by astronomers from Caltech Astro, Carnegie Observatories, Mt. Wilson Observatory, and the Los Angeles Astronomical Society. For more information, including directions, maps, parking, and weather updates, visit this website.
