For more than a month now, a European orbiter circling Mars has been watching a long, plume-like cloud on the Red Planet.

The cloud has remained in place over a mountain called Arsia Mons near the Martian equator since Sept. 13, according to a statement released by the European Space Agency (ESA). But that location is just a coincidence, the agency adds. No volcanic process is producing the cloud — the volcano hasn't been active in about 50 million years, scientists believe.

The same spacecraft, called Mars Express, and its predecessors have spotted similar clouds on at least three previous occasions, and those structures formed around the same time in the Martian year. And that's not a coincidence, the ESA wrote.

The cloud is full of water ice, the agency continued, created by air flow along the side of the volcano. This means the feature is what scientists call an orographic or lee cloud. That also happens to mean that the cloud changes over the course of the day as atmospheric patterns on Mars change.

... as little grey, fluctuating patches, spread through the clearness of the planet's atmosphere and obscured its more familiar features."
