JANUS sees Comet 3I/ATLAS at 180 million km

A red-green-blue image of 3I/ATLAS taken by Juice’s high-resolution science camera, JANUS, from more than 180 million km away. The comet seems to glow green, because gases in the halo around the nucleus are shining in light at green wavelengths. Background stars have different colours depending on their temperatures.

[Image description: A wide, dark sky is filled with countless tiny points of light, like a dense spray of stars. Near the lower left of centre, a small, soft green glow stands out among the stars, appearing slightly fuzzy compared to the sharp pinpoints around it. The rest of the scene fades into deep black space with scattered stars of varying brightness.]
