NASA astronaut Matthew Dominick has captured mesmerizing images of a red and green aurora from the International Space Station (ISS) using a T/1.8 Arri Zeiss 15mm lens on a Nikon Z9 camera. This equipment was delivered with the last cargo shipment to the ISS and he managed to capture thousands of images, with many more to come.
Time-lapse of the moon setting in streams of red and green auroras, followed by a sunrise that illuminates Soyuz in bright blue.
The auroras over the last few days have been incredible. A great time to try out a new lens that recently arrived on Cygnus.

This time-lapse shows the moon setting in streams of red and green auroras, followed by a sunrise that illuminates the Soyuz in a bright blue light. Why red and green? The green is essentially a feature of oxygen, while hints of purple, blue or pink are caused by nitrogen. As for the red color, this is mainly caused by very high altitude oxygen interacting with solar particles.
