    "dek": "A mysterious dark silhouette captured by NASA's Curiosity rover on Mars has sparked speculation about alien life or cosmic rays.",
    "prose": "NASA's Curiosity rover captured a mysterious dark silhouette resembling a 'jellyfish' with a rounded head and hanging filaments on the horizon of the Gale crater on Mars. [^1]\n\nA dark figure resembling a jellyfish appeared in a photograph taken by the NASA Curiosity rover on Mars on August 20, 2023, in the Gale crater. [^2]\n\nScientists hypothesize that the image anomaly was caused by a cosmic ray impacting the camera sensor. [^3]\n\nThe figure was not visible in other images taken by the Curiosity rover 13 and 25 seconds before or 78 minutes after the original shot. [^4]\n\nComparative analysis revealed that two photos taken 13 and 25 seconds before the anomaly appeared showed no such figure, and a photo taken 78 minutes later also lacked the silhouette. [^5]\n\nThe image was taken by the rover's right navigation camera on August 20, 2023, and remained unnoticed until it went viral on social media in August 2026. [^6]\n\nThe NASA Jet Propulsion Laboratory explained in 2014 that cosmic rays can cause bright spots or patterns in Curiosity images due to Mars's lack of a global magnetic field. [^7]\n\nScience Alert noted that Mars lacks a global magnetic field and has an atmosphere only 0.5% the mass of Earth's, leaving the Curiosity instruments more exposed to high-energy particles from space.
