Incredible new images from the European Space Agency show 'araneiforms' - also known as 'spiders from Mars'.
The creepy patterns were observed by the European Space Agency's ExoMars Trace Gas Orbiter.
The "spiders" are actually caused by frozen CO₂ melting into gas and bursting out from below the frozen surface of the Red Planet.
The creepy crawlies are actually small, dark features that form when this happens.
A rover captured signs of clustered dark dots on Mars' Inca City that resemble spiders, which formed due to seasonal eruptions of carbon dioxide gas.
