'Like a mermaid swimming through a sea of auroras': ISS astronauts photograph 2 comets dancing above the northern lights

A streak of white showing Comet Lemmon moves into a red and green aurora seen on the edge of Earth in space.

Astronauts orbiting Earth recently photographed not one but two comets while an aurora show danced below them.

The International Space Station (ISS) Expedition 73 crew took several pictures of comets Lemmon (C/2025 A6) and SWAN (C/2025 R2) in recent weeks that were just posted to NASA's website and social media pages after the end of the long government shutdown.
