Let's shrink our spirals from the astrophysical to the geological (or, maybe, "areological"?) and look at these highly mysterious spirals on the surface of Mars. Yes, they're real, and no, they weren't created by intelligent Martians.
Geologists know of these kinds of formations on Earth and they are caused by volcanic activity. Hundreds of these features, measuring up to 30 meters wide, have been spotted by NASA's Mars Reconnaissance Orbiter in Mars' Athabasca Valles. And, like their Earthly counterparts, geologists think they were formed by ancient lava flows when the Red Planet was volcanically active. Similar formations have been found in slow lava flows on Hawaii, for example.
