In the elevated scheme of matter , cosmos - wise , Marsis relatively immature ( a bare 4.6 billion years old to the universe ’s 13.7 billion ) , which stand for it could still be in its pimply form , as it appears in unexampled NASA picture .
However , what may look like a spot of acne or a hormonal gaolbreak on the Red Planet ’s aerofoil is really something even more curious : an optical magic .
Mars is no stranger to being the subject of humans ’ rummy tendency forpareidolia – determine conversant shapes likecatsormuppetsortombswhere they definitely are not – but in this font , it ’s not even that .

In this young image released this calendar week taken by NASA’sHigh Resolution Imaging Experiment(HiRISE ) , what looks like white patches on red Alfred Hawthorne is the opposite – it ’s seasonal carbon copy dioxide ice lying inside immense depression in Mars ’s South Pole .
It ’s not the first metre the surface of Mars has played visual tricks on us . This elongated infernal region in the Ceraunius Fossae in the northern Tharsis realm of Mars is also a imprint rather than a raised characteristic , despite calculate otherwise .
consort to aHiRISE blog , the cluster of crater in the unexampled image is strange because most of the craters seen near the South Pole have been individual ones . It ’s thought volcanic crater cluster form when an incoming infinite rock breaks up in Mars ’s standard atmosphere , create a closely scattered group of impact craters rather than just one .
A more recentstudyfound more than half of unexampled small shock detect by HiRISE are bunch , and that rather than Mars ’s air , it was the weakened state of the impactor rocks themselves that caused them to break up .
NASA ’s InSight recentlyrecorded the largest meteor impactto hit Mars yet , and thanks to HiRISE they even managed to find and snap the impact volcanic crater , measuring a whopping 150 meters ( 492 feet ) across .
