NEVADA CITY, Calif. April 6, 2017 – The Nevada County Astronomy Club and the Madelyn Helling Library host Astronomy Day on Saturday, April 29, 2017 from 11 am to 3 pm.  Astronomy Day features numerous educational exhibits about our place in the universe. This year’s theme, “Eclipses” includes an introduction to this summer’s solar eclipse. It will be the first in the continental US since February 26, 1979.

This year’s eclipse promises to be widely visible as it crosses the United States. Astronomy Day attendees will learn more about this spectacular event during the Solar Eclipse lecture that will take place in the new Marian E. Gallaher Amphitheater at the Madelyn Helling Library, 980 Helling Way in Nevada City, California.

Astronomy Day is an annual event established to highlight the science as a fun and educational hobby and to bring awareness to our amazing universe.  It isn’t necessary to have a telescope to appreciate the night sky and to learn more about it.

Nevada County Astronomers hold regular meeting on topics of general interest and schedule events to share their knowledge with schools and the public.

Astronomy Day features fun activities for the whole family. The highlight of the day is a Star Lab planetarium show, “The Color of Stars”. The presentations are hosted by long time astronomer Larry Harrison, an expert in conducting these shows for schools and community groups.

The planetarium is a large inflatable dome that offers visitors a chance to see the night sky in a dark environment. Regular shows will be given from noon to 3 pm; no tickets or reservation required.

Solar viewing with Nevada County Astronomers

Solar telescopes will be set up for safe viewing the sun (weather permitting) in both white light and hydrogen-alpha light. Visitors will be able to make their own star wheels to help navigate the night sky. Star wheels show constellations that are in the sky at any time and date. Another popular activity for kids is the “Hands-on Science” exhibit and the “Demonstration Science” tables. Displays include a wide variety of astronomy related topics from auroras, moon exploration, the New Horizon mission to Pluto, eclipses and much more. Several talks will be given in the afternoon including one on the upcoming eclipse.

Outside activities include a planet walk with a full-scale model of the solar system out to Mars. The model helps persons taking the walk understand how enormous our solar system really is. Everyone is welcome and there is no charge. For more information and a schedule, go to
