Astronomers Reveal the True Cosmic Colors of Comet 3I/ATLAS
2025-11-10T12:24:34.000Z Comet 3I/ATLAS continues to captivate the public. The comet is only the third known interstellar visitor to our solar system, and has been repeatedly surprising astronomers as it flies through our cosmic neighborhood. 3I/ATLAS was first discovered in July. It made its closest pass to the sun on Oct. 30, and three sun-facing spacecraft collected images of the wanderer as it zoomed past our star.
