In the lead-up to a total solar eclipse, most of the attention is on the sun, but Earth’s moon also has a starring role. “A total eclipse is a dance with three partners: the moon, the sun and Earth,” said Richard Vondrak, a lunar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It can only happen when there is an exquisite alignment of the moon and the sun in our sky.”

Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon’s eclipse of the sun to learn more about Earth’s energy system.
