The Sun (and Overall Winner)

This competition-winning photograph of the Sun is mostly a shot of the Moon. Photographer Shuchang Dong captured the Sun as it appeared with the lunar interloper in front of it, rendering our local star as just an ethereal ring during an annular solar eclipse on June 21, 2020.
Dong went to Ali, a high-altitude, low-population region of Tibet, to take the photo. The weather there is usually sunny year-round, with the exception of the day Dong took the photo, when it was cloudy. With less than a minute to spare before the eclipse, though, there was a parting in the clouds, according to a Royal Observatory Greenwich release.
