Interstellar comet 3I/ATLAS is giving scientists a unique show as it leaves our solar system. Unlike usual comets, it has unusual dust and gas patterns that shift slowly over time. These subtle movements were spotted from July to September 2025 by astronomers using the Two-meter Twin Telescope at the Teide Observatory in Tenerife. They noticed jets in the comet’s coma that wobble every seven hours and forty-five minutes. This suggests the comet is slowly spinning, with active surface spots releasing gas and dust in different directions. Scientists calculate 3I/ATLAS completes one full rotation roughly every fifteen and a half hours. The comet’s sun-facing "anti tail" — a rare tail that points toward the Sun — showed narrow jets shifting their position regularly. This is the first clear observation of such behavior in any interstellar comet. 3I/ATLAS is only the third known object from outside our solar system, following Oumuamua in 2017 and Borisov in 2019. It likely spent billions of years drifting in deep space before this close encounter with the Sun. Its unique properties help researchers understand comet formation far from our star. The comet came closest to Earth on December 19, 2025, and now it is moving away, heading out of our solar system. Its visit may be brief, but the data collected will continue to influence how scientists think about comets and planetary systems beyond Earth. As researchers say, such opportunities are rare and may not happen again soon, leaving behind more questions than answers.
