April 15 – 22 / Sunriver Nature Center & Observatory

Few sights are as awe-inspiring as viewing the splendor of the clear night sky in a location removed from impactful light pollution. The light which comes from planets, stars, and even other galaxies, travels unfathomable distances through space, and without competition from our lights here on Earth, it shines all the more brilliant and clear.

International Dark Sky Week, from April 15 – 22, 2023 provides a chance for us all to consider the negative impacts of light pollution and an opportunity to appreciate the grandeur of the night sky.

Light pollution is a serious issue with far-reaching negative consequences:
• Increased and wasted energy consumption.
• Disrupting the daily cycle of light and dark rhythm which govern life-sustaining behaviors. Artificial light has been shown to have a determinantal and even deadly effect on amphibians, birds, mammals, insects, and plants.
• Disrupting the circadian rhythm in humans can harm their health.

Started in 2003, the annual International Dark Sky Week is organized by the International Dark-Sky Association (IDA), a non-profit organization that works to protect the night environment and promote responsible outdoor lighting. The goal of International Dark Sky Week is to educate the public about the negative impacts of light pollution, inspire people to take action to reduce light pollution in their communities and encourage individuals and organizations to become advocates for preserving the natural night sky.

During the week, IDA and its partners organize a variety of activities such as stargazing events, educational programs, and community outreach activities to promote the message of dark sky preservation. Your participation helps make this International Dark Sky Week a success. There are many ways to become involved in this event, throughout the week and throughout a lifetime. Check with your local astronomy club, planetarium, or park to see if they are hosting any events during International Dark Sky Week. If there are no events in your area, consider hosting your own event. You can organize a stargazing party with friends and family, or partner with a local organization to put together a public event. As you enjoy International Dark Sky Week, share information about International Dark Sky Week on social media, and encourage your friends and family to participate. Use the hashtag #IDSW2023 to help spread the word.

There are various steps to take to help reduce light pollution in your local community. This could include turning off outdoor lights at night, using motion sensors to control lights, or advocating for more responsible lighting practices in your area. Join us as we celebrate International Dark Sky Week with a lecture from Bill Kowalik Ph.D., our local representative, for the Oregon International Dark Sky Association, at 8 PM on April 18th in the Pozzi Building at the Sunriver Nature Center. After this lecture, we will host a viewing party using the telescopes next door at the Oregon Observatory. See you there!
