Interstellar comet 3I/ATLAS is now leaving our solar system—but its rare anti-tail continues to perplex scientists with an unexpected wobble that reshapes our understanding of cosmic visitors. Astronomers around the world are still studying every detail of 3I/ATLAS even as it recedes from Earth's view, seeking answers about features no one anticipated.
The comet's most unusual behaviour was not its presence, after all, it is only the third interstellar object ever detected. But a sun-facing anti-tail showing structured jets that wobbled rhythmically every 7 hours and 45 minutes as it approached the Sun. This remarkable discovery raises new questions about how such ancient bodies behave when encountering solar heat and wind.
