The fast-moving comet likely comes from a solar system that is older than our own. This image shows the halo of gas and dust, or coma, surrounding comet 3I/ATLAS, the third interstellar object ever detected by astronomers as it passes through our solar system. The image was taken on Oct. 9, 2025, by an instrument onboard NASA's MAVEN spacecraft, which has been studying Mars from its orbit since 2014.
