This image of the interstellar comet 3I/ATLAS was captured by the JANUS camera aboard ESA’s Juice spacecraft on November 6, 2025, just seven days after the comet made its closest approach to the Sun. At the time, Juice was about 66 million km (41 million miles) away from the comet. The inset in the image shows the same data, but processed to highlight the coma structure. The arrows in the top left indicate the direction in which the comet was moving (blue) and the relative direction of the Sun (yellow). Image credit: ESA / Juice / JANUS.
