On Earth, this convection causes clouds to form because rising hot air contains water, which then condenses and falls as rain. In the dry and arid environment of Mars, however, these rising hot ...

The grainy pattern in the telescope’s “first light” image is the mark of plasma cells on the sun’s surface. Hot plasma from within the sun rises to the surface, cools and sinks back down in a process ...

Convection cell: an area in which warm and cold air circulate within the troposphere. There are three convection cells either side of the equator. Altitude: the height above sea level.

"The photosphere [the lowest layer of the sun's atmosphere] is covered by convection cells, like in a boiling pot of water, and the larger scale convection flow is called supergranulation," lead ...

The surface patterns reflect the slow overturning of salty water within the soil, a phenomenon somewhat like the convection cells that form in a thin layer of simmering water.

A detailed example of a light bridge crossing a sunspot’s umbra. In this picture, the presence of convection cells surrounding the sunspot is also evident. Hot solar material (plasma) rises in ...

A 280-Mile-Wide Ring Formed by Convection The image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite, shows a Rayleigh-Bénard convection cell in ...

"The photosphere is covered by convection cells, like in a boiling pot of water, and the larger scale convection flow is called supergranulation," Bale said.
