Aug. 21 brings the first total solar eclipse across the United States in nearly 40 years. No one under the sun is working harder to spread the word than CU Boulder’s Doug Duncan, astronomer and Fiske Planetarium director.
Fiske Planetarium’s website also offers several resources, including tips on how to watch safely and a link to an interactive map to pinpoint the best time for viewing in your location.
Every state in the Continental U.S. will have views of at least 75 percent of the sun covered by the moon. Lucky people in a 70-mile-wide swath from Oregon to South Carolina – including parts of Wyoming, Nebraska and Kansas – will witness the rare total eclipse.
And while the moon blocking out the sun is a remarkable sight to be remembered for a lifetime, it’s also an opportunity for scientists to see parts of the sun’s atmosphere that are otherwise invisible. A total eclipse presented the first chance to test Einstein’s prediction that matter can bend space – such as near a black hole.
