New Deep-Space Color Image And Revolutionary Insight About Interstellar Comet 3I/ATLAS From Jupiter-Bound JUICE MissionA 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. This is comet 3I/ATLAS. The rest of the scene fades into deep black space with scattered stars of varying brightness.

Interstellar Comet 3I/ATLAS Shines Across Deep Space In Brand New VideoA white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.

Carbon dioxide is very large and circular. Water is smaller but still circular. organics is smaller still and bit squished. the dust is instead very asymettrical longer on side than the other.
