Harper added: "It is also possible that a cool convection cell is associated with the appearance of dust, in which case both are responsible."

"So when it brightened again it was business as usual; this would follow from the convection cell idea."

One is the emergence of a large, unusually cool convection cell — a blob of cooling plasma on its surface.

One leading explanation for the dimming is the emergence of a large, unusually cool convection cell.

Observations by terrestrial telescopes suggested that the probe, which survived for less than an hour before contact was lost, ended up in the downdraft of a giant atmospheric convection cell.
