Astronomers captured bubbling cells of gas 75 times as wide as the sun in this red giant star For the first time, astronomers have watched gas boil and bubble on the surface of a distant star.

Rayleigh-Bénard convection, a classical paradigm in fluid dynamics, refers to the thermally driven instability that arises when a fluid layer is heated from below and cooled from above. This ...

On Pluto, icebergs floating in a sea of nitrogen ice are key to a possible explanation of the quilted appearance of the Sputnik Planum region of the dwarf planet’s surface. Data reported by NASA’s New ...

Rayleigh-Bénard convection, a classical paradigm in fluid dynamics, describes the buoyancy‐driven flow that occurs when a horizontal fluid layer is heated from below and cooled from above. The ...
