Solar granulation
Solar granulation. Computer artwork of granulation on the surface of the Sun. The mottled surface is showing the structure of convection cells in the photosphere (surface) of the Sun. Such a view is obtained by using the Doppler effect to measure motion towards and away from the observer. Dark colours indicate motion toward the observer, light colours show motion away. This motion indicates that convection is occurring, the phenomenon where heated gases and liquids rise, replacing cooler volumes that sink downwards. The continuing effect sets up a circulating convection current

EDITORS COMMENTS
This print titled "Solar Granulation" offers a mesmerizing glimpse into the dynamic and intricate surface of our Sun. Created through computer artwork, it showcases the fascinating structure of convection cells in the photosphere, or surface layer, of our star. The mottled appearance reveals a tapestry of circular patterns that represent the convective motion occurring on the Sun's surface. By utilizing the Doppler effect to measure motion towards and away from us, this image provides insight into these convection cells. Dark colors indicate motion directed towards us, while light hues signify movement away from us. Convection is a vital process where heated gases and liquids rise upwards, displacing cooler volumes that sink downwards. This perpetual cycle creates a circulating convection current across the Sun's photosphere. As we marvel at this stunning illustration, we are reminded of how interconnected celestial phenomena are with our understanding of astrophysics and cosmology. The study of solar granulation sheds light on various scientific disciplines such as astronomy and contributes to expanding our knowledge about our vast universe. Presented by Science Photo Library, this remarkable image invites us to appreciate both its artistic beauty and scientific significance. It serves as a testament to humanity's ceaseless curiosity about space exploration while reminding us of nature's awe-inspiring wonders found right here in our own cosmic backyard - the radiant Sun above.
