NASA’s Curiosity Rover Photographs Strange ‘Legged Object’ on Mars, Igniting UFO Theories

A mysterious image captured by NASA’s Curiosity rover on Mars has been unearthed and is sparking heated debate across the internet, with some speculating it shows a “jellyfish-like” figure with a dark body and two thin legs—a potential sign of alien life on the Red Planet . The photograph, taken on August 20, 2023, at around 6:27 PM ET, shows the rover’s typical view of the barren, dusty landscape and rocky hills of Gale Crater . However, a small figure in the left corner of the panorama has captured global attention, appearing to have a large black body perched atop two spindly structures that some interpret as legs . This image was recently reposted on X by space enthusiast Kari Sivertzen, who regularly shares public NASA images containing unusual anomalies . Her post quickly went viral, prompting a wave of reactions from users who described it as “one of the best Mars UFO photographs” they have ever seen .

Fueling the speculation that the rover captured an object in motion is a crucial detail: images taken of the same area less than a minute earlier show no sign of the mysterious figure . Furthermore, the photo with the object was the last one posted by NASA for that day, and the next image from Curiosity was taken nearly two hours later with the camera pointed in a different direction, leaving no definitive record of what happened to the object . This has led independent Mars researcher Jean Ward to comment on X that the “Jellyfish-shaped UFO/UAP Spotted on Mars… seems to be interacting with the surface” and that it reminds him of a tripod-like object . Some online commentators have even compared the distant figure to the giant alien walkers from the science fiction movie War of the Worlds , while others have offered more fantastical interpretations, such as it being a relic from a distant Martian civilization or a tower-like structure .

However, the scientific community and skeptics urge caution, offering far more mundane explanations for the phenomenon. Many argue that the small black figure is simply a camera artifact or corrupted pixels—which space officials refer to as an “artifact” . A key piece of evidence debunking one popular theory is that the object could not have been NASA’s Ingenuity helicopter, which made history with its flights on Mars but was grounded approximately 2,300 miles away in Jezero Crater at the time . This phenomenon, where the human brain perceives familiar shapes in random patterns, is known as pareidolia . It is the same psychological trick that has led people to see a “Face on Mars” in 1976, as well as other shapes like a bear’s head, a spoon, and even a small woman in images from the Red Planet over the years . NASA scientist Ashwin Vasavada has previously noted that such sightings often require zooming in on a “fuzzy shadow,” and that while the Curiosity team of 500 scientists would be thrilled to find evidence of intelligent life, “so far we haven’t seen anything that is so obvious that it would be similar to what these claims are” . While this particular mystery remains officially unsolved, it reignites public fascination with the possibility of life on Mars, a question that NASA is actively investigating. Just a year prior, in September 2025, NASA declared it had found the clearest signs of ancient microbial life on Mars, though the space agency maintains no signs of intelligent life have ever been found .
