It’s not uncommon to spot the International Space Station as a light moving across the sky just after sunset or before sunrise, when the Sun’s light reflects off it. The view you see here, though, is far from common. Chinese astrophotographer Wang Letian used a solar telescope and specialized camera to capture this series of photos, combined into a single image of the ISS passing in front of the Sun. You can see several gaseous prominences around the edge of the Sun as well as a dark sunspot.
A labor of love. Unique beauty the result.
