Caption

Thermographic footage of the surface of hot oil as it cools down. The thermal camera shows the temperature of the oil surface, with hotter areas brighter than cooler ones. Hot, less dense oil rises to the surface, where it cools, spreads out and sinks, forming convection cells. This is called Rayleigh-Bénard convection, and it occurs where a fluid is heated from below. A similar pattern is seen on the surface of the Sun, where hot plasma rises, cools and sinks to produce a pattern known as granulation.
