The interstellar comet 3I/ATLAS, discovered on July 1, 2025, has had its trajectory determined with exceptional precision. Previously, astronomers had only Earth-based observations at their disposal. However, the comet was recently sighted by the ExoMars Trace Gas Orbiter probe orbiting Mars. Engineers directed the probe's camera towards space, capturing the comet amidst a field of stars, combining these images with data from telescopes on Earth.

Following its solar approach, the Juice probe near Jupiter will assume the responsibility of monitoring the comet in its active phase. The results of these observations are anticipated in February 2026, providing further insights into the interstellar visitor's behavior.
