NASA recently released images of eight dust devils swirling in the same vicinity on Mars.

Technology is providing deeper views of Mars including an interesting phenomenon called a dust devil. 
Dust devils resemble mini-tornadoes but are not formed from the energy of a storm; instead, they rely on a lift of hot air swirling around a low-pressure system which creates a swirling funnel effect. 
A few months ago, scientists were able to capture eight of these vortices in action around the Ganges Chasma area of the Red Planet; images were released in November. 
What stood out to scientist Paul Geissler were two dust devils located about 820 feet apart.
