ESA's JUICE uses five instruments to probe activity and composition of interstellar comet 3I/ATLAS
In November 2025 ESA’s Jupiter Icy Moons Explorer (JUICE) targeted interstellar comet 3I/ATLAS with five science instruments, collecting remote‑sensing data on the object’s activity, coma chemistry and dust to characterise its behaviour and composition during the visitor’s inner‑solar‑system passage.
