On Sept. 7 2025, the skies darkened as Earth's shadow consumed the moon. Skywatchers in many parts of the world saw the moon turn blood red due to a total lunar eclipse.

For amateur astronomers Michael Jäger and Gerald Rhemann in Namibia, the eclipse was not only a sight to behold, but it also gave them an unprecedented opportunity: the chance to capture the interstellar comet 3I/ATLAS under some of the darkest skies on Earth.

Using the eclipse's natural dimming of the moon, the duo was able to take some deep images of the comet, revealing something surprising: the comet glowed green.
