The dunes are a "mesospheric bore," a type of atmospheric gravity wave that springs up from Earth's surface and gets caught in a thermal waveguide ~100 km high.

That’s wild, it looks like someone left fingerprints on the sky. Hard to wrap my brain around that being a literal wave trapped 100 km up and not some long exposure trick.
