ESA's JUICE Spacecraft Captures Interstellar Visitor 3I/ATLAS on Its Journey Back to Deep Space.

Images of the Interstellar Object 3I/ATLAS

According to TSN.ua: The European Space Agency (ESA) has released images of the interstellar object 3I/ATLAS, captured as it began its journey back into deep space. The photos were taken by the JUICE spacecraft, whose primary mission is to explore Jupiter's moons. Observing such interstellar visitors is rare, providing a unique opportunity to study material from beyond our solar system. 3I/ATLAS will make its closest approach to Jupiter in mid-March, while JUICE itself will not arrive at the giant planet for several more years.

In November 2025, JUICE took over one hundred photographs of 3I/ATLAS from a distance of 66 million kilometers. The observations were conducted at the object's perihelion, when it was 210 million kilometers from the Sun. Scientists collected 120 images and data from various JUICE instruments, enabling a deeper analysis of the object's characteristics.

The JUICE Mission and the 3I/ATLAS Investigation

JUICE's core mission will commence in the 2030s, focusing on the study of Jupiter's moons: Ganymede, Callisto, and Europa. Olivier Witasse, a project scientist, noted:

"This observing campaign was an unexpected bonus for JUICE." - Olivier Witasse

Therefore, the study of 3I/ATLAS opens new horizons for future space missions and our understanding of the solar system.

Investigating the interstellar object 3I/ATLAS is a significant milestone for the JUICE spacecraft, as it allows scientists to gather new data on objects originating from outside our planetary system. This data can aid in the future study of not only Jupiter but also other planets and their moons, which is crucial for understanding the evolution of our solar system. As JUICE's main mission approaches in the 2030s, the results from the 3I/ATLAS observations may form the foundation for new discoveries in astronomy and planetary science.
