The European Space Agency’s Mars Express orbiter has spotted “spiders” on the Red Planet’s southern polar region.

But they’re not the arachnids we fear or adore back on Earth — they’re the result of a complex geological process that causes carbon dioxide to sublimate, digging up darker material from below the surface during the planet’s spring.

And they’re a whole lot larger than the spiders you’re used to, measuring up to 3,300 feet across.

Many of these spots have been found outside of a Martian landscape dubbed Inca City (formally Angustus Labyrinthus) thanks to its geometric ridges that summon to mind Inca ruins.

    Spoiler alert: the orbiter has not spotted spiders on the surface of Mars.

      I’m a huge space nerd, but I absolutely hate space related news because they’re pretty much all just some dumb clickbait bullshit. I’m surprised they didn’t call those “spiders” mysterious.

      And the Inca City isn’t a city and is not related to the Incas. Or that’s what The Man would have you believe.

    I, for one, welcome our new arachnid overlords.

      If large enough to be spotted from orbit.

      I’m fairly sure they don’t care what there pepperoni slices think.
