ESA's Juice Spacecraft Captures Detailed Images of Interstellar Comet 3I/ATLAS

The European Space Agency's Jupiter Icy Moons Explorer (Juice) has transmitted detailed images of interstellar comet 3I/ATLAS, offering new insights into this rare celestial visitor. Captured on November 6, 2025, by Juice's JANUS science camera, the images reveal the comet's bright coma and an extensive tail composed of gas and dust. At the time of imaging, Juice was approximately 66 million kilometers from the comet.

3I/ATLAS, the third known interstellar object to traverse our solar system, was first detected in July 2025. Originating from beyond our Sun's influence, it exhibits characteristics typical of comets, including a hyperbolic trajectory and outgassing activity as it approaches the Sun.

In addition to the JANUS camera, Juice utilized four other instruments—MAJIS, SWI, PEP, and UVS—to observe the comet throughout November 2025. These instruments collected data on the comet's composition and behavior. Due to Juice's position on the opposite side of the Sun from Earth, data transmission was delayed, with scientists receiving the information in February 2026. Analysis of this data is ongoing, with a comprehensive review scheduled for late March 2026.

The new images and data from Juice are expected to enhance our understanding of interstellar objects and the processes governing cometary activity.
