3I/ATLAS suddenly 'wakes up' in deep space, the European Space Agency's (ESA) JUICE spacecraft has captured the first sign of dramatic activity in the comet, revealing a glowing halo and possible tails far beyond Earth's gaze.
Since its discovery by the ATLAS survey on 1 July 2025, 3I/ATLAS has intrigued astronomers as the third known interstellar object ever to enter our Solar System. Observed from Earth and Mars in recent months, the comet has now drawn the attention of JUICE, ESA's Jupiter-bound probe, which on 2 November 2025 used its onboard Navigation Camera (NavCam) to capture a startling image of the object surrounded by signs of vigorous outgassing.
