Comet 3I/ATLAS Today (Nov 7, 2025): New Mars‑orbiter images, how to see it before dawn, and what scientists are learning about this interstellar visitor
China’s Tianwen-1 probe has released new images of interstellar comet 3I/ATLAS from Mars orbit, following similar data from ESA’s ExoMars orbiter. The comet, only the third confirmed interstellar object, reappeared after passing behind the Sun and can now be tracked with public tools. Closest approach to Earth will be December 19 at about 270 million km. No hazard to Earth has been reported.
