NASA's alien-hunting Europa Clipper spacecraft took seven hours of ultraviolet observations of interstellar comet 3I/ATLAS while both objects zoom toward Jupiter.

The United Nations' International Asteroid Warning Network (IAWN) has activated a broad campaign, rallying support from Nasa and over 80 observatories, to follow comet 3I/ATLAS.

It is set to make its closest approach to Earth on December 19, 2025.
