Mysterious stripes spotted over Russia in satellite images — and NASA is perplexed

Near the Markha River in Arctic Siberia, the earth ripples in ways that scientists don’t fully understand.

Earlier this week, NASA researchers posted a series of satellite images of the peculiar wrinkled landscape to the agency’s Earth Observatory website. Taken with the Landsat 8 satellite over several years, the photos show the land on both sides of the Markha River rippling with alternating dark and light stripes. The puzzling effect is visible in all four seasons, but it is most pronounced in winter, when white snow makes the contrasting pattern even more stark.
