These clouds are not from earth, but Mars! The red planet does have a thin atmosphere capable of some weather and NASA's Curiosity rover has been recording it.
The rover captured over 500 clips of cloud formations during its 5 years on Mars. This latest video shows "Gravity Waves" . These "cloud ripples" are formed on earth by air trying to even out its vertical balance.
Gravity Waves on Mars
Scientists hope that by learning how "Gravity Waves" form on Mars, it will lead to figuring out how deep the ice sheets are on the planet. This in turn may lead to a better understanding of the watery past on Mars.
