✨Comet 3I/ATLAS: IAWN kicks off its observing exercise! While posing no threat to Earth, interstellar #comet 3I/ATLAS presents a valuable scientific opportunity. The International Asteroid Warning Network (IAWN) is now conducting an observing exercise during the comet’s visibility window: 27 November 2025-27 January 2026. This campaign helps astronomers practice how to accurately determine comet positions — a key skill for planetary defence. 🔭 📸✨From Earth orbit to Mars, spacecraft across the solar system have already been capturing the journey of 3I/ATLAS. Here are a few of the images so far! 🔗 🎥See our YouTube explainer via the link in bio!
