“The Greeks, Einstein, and Alien Worlds: The Importance of Eclipses”
Most of us just witnessed the Great Solar Eclipse of 2024. A total solar eclipse is both majestic and humbling, an experience humanity has shared for tens of thousands of years. But we also use eclipses for science. The Greeks could measure the distance to the Moon and even get a rough distance to the Sun using eclipses. Eclipses were used to test and verify Einstein’s theory of gravity. We have used them to measure the diameters of stars. And to me, most intriguing, we use eclipses to find alien planets in our search for life elsewhere in the Universe. Come explore the science of eclipses, which has profoundly influenced discovering our place in the Cosmos.
