Often living up to its nickname, Mars often looks like a desolate red wasteland<\/a> in images shared by NASA<\/a>. However this hasn’t stopped online sleuths from pouring over satellite imagery in hopes of finding signs of life.<\/p>\n And of course, anyone who looks long enough is bound to find something.<\/p>\n One particular image which has captured the attention of alien sleuths is the image of an ‘exclamation mark’ landmark on the planet.<\/p>\n Captured in 2011 by NASA’s Mars Reconnaissance Orbiter (MRO), the spacecraft was able to capture the image of what appeared to be a giant exclamation mark on the Libya Montes highland area of the Mars.<\/p>\n Could this be finally be evidence of the long lost alien civilisation we’ve all been looking for? As always, it depends on who you ask.<\/p>\n One supporter of this theory is George J. Haas, founder of Mars research group The Cydonia Institute, who recently told<\/a> MailOnline: “You don’t have to be a geologist to know the difference between a rock and a sculpture.”<\/p>\n “There’s no way you can explain that keyhole formation,” he continued, adding: “The natural creation of two opposing geometrically designed formations seems to go well beyond the probability of chance.”<\/p>\n The ‘exclamation mark’ isn’t the only landmark which Haas has flagged as suspicious over the years either, with the author highlighting images such as pyramid-like structures which were captured by astronomer Carl Sagan in 1972 as well as geometric patterns which resemble ancient cities and the infamous ‘face’ in the planet’s Cydonia region.<\/p>\n However, not everyone would agree, with many scientists arguing that it is all down to a phenomena known as the ‘pareidolia effect<\/a>‘.<\/p>\n![\"What](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/04\/nasa-structures.png\"\/)
