Mars Jellyfish Photo Explained: A Cosmic-Ray Glitch, Not a Creature

A jellyfish-shaped shadow spotted in a 2023 Curiosity NavCam image is not a real Martian organism but a cosmic-ray artifact hitting the camera sensor; such glitches are common on Mars due to its thin atmosphere and lack of a global magnetic field, and are typically seen in a single frame or a few frames, not on the surface. NASA/JPL notes that without detailed imaging analysis, the anomaly is best explained as a camera artifact rather than evidence of life.

Curiosity's Mars tripod debunked as a brief camera glitch

NASA's Curiosity rover captured a brief, tripod-like speck in Gale Crater that went viral, but experts say it’s almost certainly a camera artifact caused by a high-energy particle hitting the NavCam sensor, a common cosmic-ray effect; the object appears in only one frame and is not seen in frames taken seconds before or after, suggesting no physical structure was present.

Mars Jellyfish Myth Debunked: Cosmic Rays Create a Camera Glitch, Not a Creature

NASA's Curiosity captured a jellyfish-like dark mark in a 2023 NavCam image, but scientists say it's almost certainly a cosmic-ray artifact hitting the camera sensor rather than a Martian jellyfish; Mars's thin atmosphere and lack of a global magnetic field let cosmic rays strike detectors, and Curiosity routinely takes multiple frames to distinguish real features from glitches.
