Solar Granulation

Description
Solar Granulation
(a) High-resolution photographs of the Sun’s surface reveal a blotchy pattern, called granulation. Granules, which measure about 1000 km across, are
convection cells in the Sun’s photosphere. Inset: Gas rising upward produces the bright granules. Cooler gas sinks downward along the darker, cooler
boundaries between granules. This convective motion transports energy from the Sun’s interior outward to the solar atmosphere.
