Be it any photograph, if taken by NASA’s curiosity rover catches attention of all the red planet enthusiasts, specially UFO theorists. Fossils on the barren and rocky land of the red planet are often considered as proof of life that once existed on Mars.

Recently an image shared by NASA shows a rock eerily resembling fish. The image has once again sparked the speculations if there was once a life on Mars. "Our study provides a solid estimate of how much water Mars once had, by determining how much water was lost to space, “Geronimo Villanueva, a scientist at Nasa's Goddard Space Flight Center in Greenbelt, Maryland had said in 2015. "With this work, we can better understand the history of water on Mars.”

The black and white photo taken on March 23 shows the surface of the planet riddled with large rocks. Though this is not for the first time when UFO hunters have come up with such mysterious findings on Mars, earlier shapes resembling giant crabs, coffins and gorillas, besides pyramid-like formations have been in the news.
