ISLAMABAD-A mysteriously lengthy, skinny cloud has once more appeared over the 20-km (~12 miles / 65,000 toes) excessive Arsia Mons volcano on Mars. The cloud is made up of water ice, however regardless of appearances, it’s not a plume linked to volcanic exercise. As an alternative, the curious stream varieties as airflow is influenced by the volcano’s ‘leeward’ slope − the aspect that doesn’t face the wind. This picture of the cloud, which might attain as much as 1800-km in size, was taken by the Visible Monitoring Digital camera (VMC) on Mars Categorical, which has been finding out the Pink Planet from orbit for the previous 16 years.
“We have been investigating this intriguing phenomenon and were expecting to see such a cloud form around now,” explains Jorge Hernandez-Bernal, PhD candidate on the College of the Basque Nation (Spain) and lead writer of the continuing research.
