When I learned that a meeting of my division of the American Astronomical Society would be held in the path of totality of the August 21st eclipse, I knew it was a once-in-a-lifetime opportunity. Having never been to Idaho, my family and I planned a winding trip from Salt Lake City through Twin Falls and on to Sun Valley, where the meeting is being held.
On the morning of the eclipse, we woke to beautiful blue skies. We took the Challenger Ski Lift 3,000 feet up to the 9,100 foot summit of Bald Mountain, our viewing location for the eclipse. Sun Valley is near the southern edge of the 70-mile wide path of totality, so we would only get about a minute of darkness. With such a short eclipse, I planned on taking zero photos of the moment itself.
The moment of totality is indescribable. As an astronomer, I knew that I would see the corona–the Sun’s tenuous outer atmosphere–but I wasn’t prepared for how it would make me feel. One of the things I’ve always loved most about astronomy is the beauty of the universe. You don’t have to know about stellar evolution to appreciate the arcing tendrils of a supernova remnant. But so many astronomical images are not what the objects look like to our eyes. The corona is different. It’s as magnificent as the best pictures of it you’ve ever seen, but the only way to see it is to be in a tiny geographic area at exactly the right moment… and get really lucky with the weather. I took a brief moment to look around the sky and see Venus and a few bright stars in the daytime sky–always there but hidden by the light of day.
And then, with a flash of light on its edge, the Sun returned. All the emotion, the elation, the joy came pouring out. Everyone was hugging and crying, high-fiving and whooping. It’s a remarkable coincidence of nature that our Moon and Sun are nearly the exact same size in the sky. Were the Moon larger or closer to the Earth, we would still have eclipses but the magic of the corona would be obscured. Any smaller or further away, and all eclipses would be partial. To experience such a rare cosmic event from such a beautiful place in the world was humbling and awe-inspiring.
And now the work begins. I will spend the next few days at my conference. Learning, working with collaborators, sharing results, but the conversation will always turn to the eclipse.
