Stargazing on Mars: Mysterious Streak in Sky May be Interstellar Comet 3I/ATLAS

2025-10-07T11:33:49.000Z NASA's Perseverance Mars rover caught something unusual streaking across the sky above the Red Planet. On Saturday (Oct. 4), Perseverance's Right Navigation Camera (Navcam) captured an image of a streak of light in the sky above Mars. The date of the image coincides with when interstellar comet 3I/ATLAS was set to make its closest pass to the Red Planet, according to the European Space Agency (ESA).
