Fleeting darkness blankets the Australian outback, as the sun appears blotted out by a total solar eclipse above Pormpuraaw, Queensland, Australia, last November.
"From this stunning location, we were able to observe the moon's umbral shadow cone of this low-altitude eclipse race across the sky, above a quintessential Australian outback locale," says photographer Geoff Sims.
During a solar eclipse, as the moon moves between Earth and the sun, the natural satellite's shadow is cast onto our planet. During the eclipse, only sky-watchers within the moon's hundred-mile-wide (160-kilometers-wide) shadow saw the sun completely "disappear."
This shot captured the judges' attention because it "creates a short, bizarre nightscape, and the phenomenon strongly connects astronomy and nature," says Tafreshi.
