Night sky topic of presentation

Columbia Gorge Discovery Center presents “Lights Out: Going Dark in the Columbia Gorge,” Friday, Jan. 22.

Bob Yoesle, president of Friends of Goldendale Observatory, will talk about the effects and hazards of light pollution.

A beef stroganoff dinner will be served at 6 p.m. for $16, followed by the 7 p.m. program, which is free to the public. Columbia Gorge Discovery Center is located at 5000 Discovery Drive, The Dalles.

Once a source of wonder and enjoyment, the star-filled nights of just a few years ago are rapidly vanishing in a foggy haze of artificial light.

The effects of bad night-time lighting is cumulative and adds up quickly: Light pollution not only masks our view of the stars; poor lighting is ugly, threatens public safety, and wastes energy to the tune of $2.2 billion per year in the U.S.

Dark-sky friendly lighting does not require you to live in darkness or turn off all the lights at night – only the unnecessary ones. Light pollution is that rare issue that costs less to solve than continue.

Learn how glare lighting actually threatens public health and safety, and how to implement outdoor lights that are designed to save energy and money, and keep and protect our dark-skies for current and future generations.

An amateur astronomer for over 50 years, Bob Yoesle was raised in the San Francisco Bay Area, and moved to the Northwest 37 years ago. Yoesle does frequent observations and education about the sun, and renewable energy from the sun, as well as astronomy.

To RSVP call the center at 541-296-8600 ext. 201 between 9 a.m. and 5 p.m. daily or visit www.gorgediscovery.org. Please RSVP by Jan. 20.
