However, experts have in the past said such stone circles may form as a result of natural processes that also occur here on Earth.
For example, the freeze-thaw cycle of permafrost can cause sediment to churn and separate by grain size that can cause boulders or large rocks to produce stone circles or polygons on low slopes.
The stone circle was highlighted on the Facebook page of a group called Journey to the Surface of the Mars, which regularly pinpoints unusual 'alien' features.
The stone circle on Mars was spotted in images captured by the High Resolution Imaging Science Experiment, or HiRise, camera on board the Mars Reconnaissance Orbiter.
