Mysterious space rock captured passing by our solar system

The European Space Agency’s Juice spacecraft captured over 120 images revealing the comet’s bright coma and long tail, aiding scientists in studying its unusual features.

  • Releasing a striking new image, ESA said the JANUS camera aboard the Juice spacecraft captured it on Nov. 6, 2025.
  • A study earlier this month reported the object experienced a dramatic increase in brightness two months after perihelion, and a scientific paper co-authored by Harvard astrophysicist Avi Loeb warned it could be a hostile spacecraft.
  • The JANUS camera collected more than 120 images of 3I/ATLAS across a wide wavelength range from about 66 million km, revealing a bright coma, long tail, and hints of rays, jets, streams and filaments while the tiny nucleus is not visible.
  • Following the release, instrument teams are examining all the JANUS images as a paper co-authored by Avi Loeb warned `The consequences, should the hypothesis turn out to be correct, could potentially be dire for humanity, and would possibly require defensive measures to be undertaken`.
  • If confirmed as natural, the jets, filaments and long tail will inform understanding of interstellar visitors' composition and post‑perihelion behaviour, while Avi Loeb's hypothesis influences ongoing debate.
