Current estimates are that over 150 million Americans viewed the great American solar eclipse on August 21, 2017 with another 60 million viewing it electronically from TV or the internet. It’s amazing to think that we are still using this opportunity to do new and exciting science even though eclipses are a regular occurrence. Eclipses are the “obscuring of the light from one celestial body by the passage of another between it and the observer…” In reality, the concept of eclipses in science has been a tried and true technique to do amazing new things from finding new rings at Saturn to new planets orbiting other far away suns. This is a brief story of how we continue to use the eclipse technique to do uncover new science.
