Researchers used Halloween SFX to simulate the Martian south pole in springtime.
NASA/JPL-Caltech/Univ. of ArizonaFirst discovered more than 20 years ago, “Mars spiders” are not freaky eight-legged aliens. Instead, the term refers to dramatic fractal contours carved into the surface of the red planet, with dark valleys radiating out like arachnid limbs. Now, scientists have demonstrated on Earth what may actually cause these unique martian features: the sublimation of carbon dioxide-rich ice at the south pole.

“It is exciting because we are beginning to understand more about how the surface of Mars is changing seasonally today,” said planetary scientist and lead author Lauren McKeown in a
