Solar flare erupt from the sun

How 1,000 undergraduates helped solve an enduring mystery about the sun

May 9, 2023

For three years at the height of the COVID-19 pandemic, CU Boulder students enrolled in "Experimental Physics I" spent an estimated 56,000 hours analyzing the behavior of hundreds of solar flares. Their results could help astrophysicists understand how the sun's corona reaches temperatures of millions of degrees Fahrenheit.
