human being have been seeing unusual thing on the surface of Mars for 100 . Perhaps it ’s because , other thanEarth , Mars is the close thing in thesolar systemto a habitable major planet , or perhaps it ’s just because it ’s close enough to get a jolly good aspect at .
Either style , earthling have been fooled metre and again by the rocky Martian surface and their own psychological science . From spooky , humanoid figure to books , bears , and beatles , here are some of the most iconic illusions humans have spotted on the Red Planet .

1. A Martian ‘book’
Perhaps weary from hunt for evidence of ancient water , NASA ’s Curiosity roamer need a short break in April 2023 to leaf through the pages of an old Martian hardcover lying in the dust of Gediz Vallis . While the strange aim may look likea book with a unmarried page suspend mid - turn , it is in fact just a rock — and a belittled one at that . The charming petty book - sway amount just 1 column inch ( 2.5 centimeters ) wide , according to NASA . At least it ’s travel - size !
2. A teddy bear’s face
In an figure of speech shared January , 2023 by The University of Arizona ( UA ) , what seems to be the face of anenormous Martian teddy bear — complete with two beady center , a push button olfactory organ and an upturned mouthpiece — grinning at the camera of NASA ’s Mars Reconnaissance Orbiter ( MRO ) . According to UA , the cuddly - wuddly formation is potential just a break - up James Jerome Hill in the middle of an ancient crater .

3. Frozen ‘flowers’
Branching outwards like a diminutive coral , thisdelicate mineral floweris about the confining thing to greenery one can discover on the Red Planet today . Mineral deposit like these are common sights across Mars , and result from ancient water mix with ancient rock . Still , it ’s rarified to see a deposit that ’s so dead flower - like , NASA researcher said . Curiosity distinguish this floral feature film in Feb. 2022 .
4. Martian ‘person’
In 2007 , theMars roverSpirit catch quite a vision in its Red Planet home : what come along to be a human being wearing a robe and kneeling in supplicant . Spirit captured a bird’s-eye opinion of the plateau called Home Plate , located in the intimate basin of the Columbia Hills range inside Gusev Crater . Of course , the " human " in the picture is merely a rock , which morphs into human form in our mind because ofpareidolia .

5. ‘The face’
It all started back in 1976 , when NASA resign an image of an interesting mountain on Mars , taken by the Viking 1 spacecraft , complete with a subtitle that discover the formation as appearing to have eyes and nostrils . More than 30 eld later , the " Face on Mars " still inspiresmyths and conspiracy theories , with many mass believe it to be an artificial structure build by an ancient Martian civilisation .
From a bird’s - eye view , shadows on the mountain really do make it look like a face . From other angles , however , seen in photos taken by the Mars Express Orbiter and other ballistic capsule , the mountain is clear just that , and does n’t wait much like a face at all .
6. The face… of Ghandi
The 1976 Mars face was just the start . With the launch ofGoogle Marsin 2009 , a map program created from compiled planet simulacrum of the satellite , users could careen around the surface of the Red Planet , finding all sorts of interesting lumps and bump . One such protrusion , discovered by an Italian man named Matteo Ianneo , look spookily like Indian independence activistMahatma Gandhi , who was assassinated in 1948 .
gamey - declaration imaging show the pattern to be not a mountain or hill , but a nether region , which does indeed look a bit like a human head in visibility , though what looks like an center and brow in the Google Mars image is less pronounced in the gamey resolution scene .
7. Martian ‘animal tracks’
Did alien creatures once skitter across the surface of Mars , leave fossilised track embedded in the Rock ? One researcher made this controversial title in 2018 , pointing to images of marijuana cigarette - like structures , each about the sizing of a grain of rice , criss - cross a Martian rock . NASA research worker chop-chop debunked the claim , mark that similar features are plentiful on Earth in country where table salt become concentrated in water , such as melt lake . Their bearing on Mars is yet more evidence of past river and lakes on the Red Planet — but still offer no trial impression that living creatures ever adorned its Earth’s surface .
8. A bushel of ‘blueberries’
blueberry are not a important source of smoothing iron when consumed on Earth — but thesegeological " blueberries " find by NASA ’s Opportunity roveron Mars in 2004 are work up differently . These iron - rich spheres , polished smooth by plentiful amount of pee billions of years ago , are some of the earliest grounds scientist have of Mars once being an fantastically besotted world . Whether they also smack honest on cheesecake is a question for future generations to grapple with .
9. Land and sea
In 1784 , Sir William Herschel , a far-famed British astronomer , wrote that dingy area on Mars were sea and lighter country were landed estate . He speculated that Mars was inhabited by levelheaded beings who " probably savour a situation alike to our own , " accord toNASA . Herschel ’s theory endure for a 100 , with other astronomers take that vegetation could even be observed in the lighter - colored regions that were taken to be land . Fortunately for Herschel , his other contribution to uranology — which have earned him the pureness of being the namesake of two powerful observatories — were great enough to keep his theories on Martians near the bottom of his biography .
10. A sci-fi forest
In 2001 , seven years before he died , the famous science fabrication author Arthur C. Clarke , co - creator of " 2001 : A Space Odyssey " , announced that he had make out patches of botany , including trees , in newfangled photos of Mars use up by the then - revolve Mars Global Surveyor . " I ’m quite serious when I say , have a really good look at these new Mars images , " Clarke said at the metre , speaking via phone during the Wernher von Braun Memorial Lecture serial at the Smithsonian ’s National Air and Space Museum . " Something is actually moving and change with the season that suggests , at least , vegetation . "
The branches that Clarke cerebrate he watch on the Martian Earth’s surface arewhat Mars geologists call " spider " : They do count like branch , and they do vary seasonally , but they ’re due to the seasonal melting of the C dioxide methamphetamine cap that subsist at Mars ' perch . When the CO2 ice sublimate turn into a gasolene it flow out along way that look like branches , Live Science previously account .
11. A hairy blue spider
Images withdraw by aEuropean Space Agency(ESA ) orbiter in 2019 seem to show anenormous hairy spidersprawling out its legs across a Martian mountain .
The reality is almost nerveless . These lank " legs " are really the paths of century of tiny tornadoes , or debris devils , that have traversed the ridgepole . It ’s not vindicated why the mountain is such a crack cocaine hotspot , but ESA scientists said that the way aura masses move around the region might be contributive to the organisation of the dust devils .
12. Or maybe a beetle?
consider creepy - crawlies seems to be a theme on Mars . Also in 2019 , William Romoser , a professor emeritus who studies viruses in insect and other arthropod made a surprising call : He state he could seebeetles and other insect , and even reptiles , on the Earth’s surface of Mars .
Romoser come to this decision after examining photographs taken by the NASA Mars rovers , which show stack of vaguely ellipse , blobby shapes on the Martian surface . But pareidolia strikes again : What else looks like a vaguely oval blob ? Most sway .
" I do not suppose there are dirt ball on Mars . The picture that are in that jam spillage you beam are whole unconvincing , as they fall within the range expected in jillion of non - insect object photographed in lowish result on a Marscape , " David Maddison , a professor in the consolidative biology department at Oregon State University , tell Live Science at the time . " It is vastly more penurious to presume the blob are simply rocks . As has been said , ' extraordinary claims require extraordinary evidence ' ; those picture are far , far less than extraordinary . "

13. A cartoon splatter
Finally , something that reckon like what it really is . Sometime between July and September 2019 , a outer space object — a meteor perhaps , or a fragment of comet — hit the southerly methamphetamine cap of Mars and punctured a tenuous layer of methamphetamine hydrochloride , dart a shower bath of red dust up and out of the hollow . The resultant is adark reddish splatthat looks like something a cartoon persona might make while work headlong into a rampart . A large photographic camera call HiRISE ( High Resolution Imaging Science Experiment ) aboard NASA ’s Mars Reconnaissance Orbiter enchant the splat , which is about 0.62 miles ( 1 km ) across .
14. A green rock with drill holes
Mars , as we all know , is the Red Planet . So what ’s withthis weird green rockdiscovered by the Perseverance roamer , and how did it get permeate with little jam ?
Everyone would like to know . " Is it something weathered out of the local basic principle ? , " atweet postedMarch 31 by the rover ’s PR team wondered . " Is it a piece of Mars plopped into the arena from a far - flung wallop case ? Is it a meteorite ? Or something else ? "
The rock ‘n’ roll is about 6 inches ( 15 centimeters ) long and sits in Mars ' Jezero Crater , secretive to the rover ’s landing internet site . The wanderer has already zapped the rock-and-roll with a laser to vanish part of it . The vapour swarm will be psychoanalyse by the rover ’s camera and spectrometer to reveal its chemical typography . Perhaps we ’ll have an result to this mystery rather rather than later on .
15. The ‘canals’ of Mars
During Mars ' airless plan of attack to Earth in 1877 , the Italian astronomer Giovanni Schiaparelli peered through his scope and observed groove on the Red Planet ’s surface . The Italian word he used for them,“canali , " meaning channels , was translated to " canals"in English , leading many in the English - speaking domain to conclude that Mars had intelligent living that had built a system of waterways .
The theory was debunked in the former 20th century , when it was demonstrated that the " canals " were simply ocular illusion : When viewed through hapless - quality telescopes , pointlike features , such as Mars ' mountains and craters , seem to be joined together by consecutive line . Later , spectroscopic analysis of the illumination coming from Mars show that there was no pee on its open .
