The answer lies nearly 25 kilometers above Earth&rsquo;s surface in the stratosphere, where the August 2017 eclipse offered researchers a rare opportunity to mimic conditions on the Red Planet.</p> https://www.earthmagazine.org/article/geomedia-books-solar-eclipses-past-present-and-future/ Mon, 09 Apr 2018 10:54:25 -0400 https://www.earthmagazine.org/article/geomedia-books-solar-eclipses-past-present-and-future/ <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/geomedia-books-solar-eclipses-past-present-and-future/AmericanEclipse_Baron.jpg" alt="American Eclipse: A Nation&#39;s Epic Race to Catch the Shadow of the Moon and Win the Glory of the World, by David Baron, Liveright/W.W.

I witnessed about one minute and 50 seconds of totality from Salem, Ore., where the skies were unusually clear — despite the wildfires then raging around the West. In eclipse parlance, totality refers to the period when the moon — which, in the most mind-blowing of cosmic coincidences, just happens to be the same angular size in the sky as the sun — completely blocks the sun&rsquo;s bright disk and reveals the tenuous outer solar atmosphere known as the corona.</p> https://www.earthmagazine.org/article/benchmarks-may-29-1919-solar-eclipse-proves-relativity/ Thu, 05 Jan 2012 06:41:58 -0500 https://www.earthmagazine.org/article/benchmarks-may-29-1919-solar-eclipse-proves-relativity/ <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/benchmarks-may-29-1919-solar-eclipse-proves-relativity/Dyson,%20Eddington,%20Davidson" alt="" loading="eager" decoding="async"> </figure> <figure class="earth-figure"> <img src="https://www.americangeosciences.org/static/earth/benchmarks-may-29-1919-solar-eclipse-proves-relativity/Cristian%20Matei" alt="" loading="lazy" decoding="async"> </figure> <p>On May 29, 1919, the moon&rsquo;s silhouette crept slowly over the sun, bringing premature night to observers in a broad swath of the Southern Hemisphere between South America and Africa. Few onlookers realized that this event would provide the first successful test of Albert Einstein&rsquo;s theory of relativity.</p>
