WebNov 29, 2024 · The composition of the solar photosphere, and by extension the solar wind, is 96% H and 4% He, with the remaining ions composed of all elements in their solar abundance ratios 28,29. In the Sun's photosphere, the most ubiquitous phenomena are granules—convection cells of plasma each approximately 1,000 km (620 mi) in diameter with hot rising plasma in the center and cooler plasma falling in the spaces between them, flowing at velocities of 7 km/s (4.3 mi/s). Each granule has a lifespan of only about twenty minutes, resulting in a continually shifting "boiling" pattern. Grouping the typical granules are supergranules up to 30,000 km (19,000 mi) in diameter … binson\u0027s home health

WebDuring a total solar eclipse, the photosphere of the Sun is obscured, revealing its atmosphere's other layers. Observed during eclipse, the Sun's chromosphere appears (briefly) as a thin pinkish arc, and its corona is seen as a tufted halo. The same phenomenon in eclipsing binaries can make the chromosphere of giant stars visible. WebMar 6, 2024 · Photosphere: Solar Prominence Solar prominences are bright loops of solar matter.
