EPOD will collect and archive photos, imagery, graphics, and artwork with short explanatory captions and links exemplifying features within the Earth system. The community is invited to contribute digital imagery, short captions and relevant links. Sun Granules May 25, 2022 Solar granules 18082017 1249 Photographer: Matteo Vacca Summary Authors: Matteo Vacca; Cadan Cummings The photograph above shows granules on the photosphere of the Sun. These irregularly shaped features are produced by plasma convection currents below the Sun’s surface. Convection occurs when fusion reactions heat opaque gases, which causes them to rise to the surface and subsequently emit energy. Several million granules cover the Sun’s surface at any time; however, they usually last between 8 to 20 minutes before dissipating. To give a sense of scale to the photo, an average solar granule has a diameter of about 930 miles or 1500 kilometers. Always protect your eyes when observing the Sun. * Milis, Sardinia, Italy Coordinates: 40.0487, 8.6370 Related EPODs Sun Granules Violet and Green Flashes at Sunset Panoramic View of Etna and the Winter Solstice Solar Eclipse From the Air Over the South Atlantic Ocean Clouds In a Fiery Sunset Analemma Observed in Taipei, Taiwan More...
