Lucy imagery of 3I/ATLAS

The interstellar comet 3I/ATLAS, circled in the center, as seen by the L’LORRI panchromatic, or black-and-white, imager on NASA’s Lucy spacecraft. This image was made by stacking a series of images taken on Sept. 16, 2025, as the comet was zooming toward Mars. Lucy was 240 million miles away from 3I/ATLAS at the time making its way to explore eight asteroids that share an orbit with Jupiter. The L’LORRI imager captured the comet’s coma, the fuzzy halo of gas and dust surrounding 3I/ATLAS above, and its tail, a smudge of gas flowing to the right of the comet. This image spans about 11 arcminutes of sky, or roughly one-third the width of the full Moon. Solar system north is up.
