Solar photosphere
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 … Webphotosphere, visible surface of the Sun, from which is emitted most of the Sun’s light that reaches Earth directly.

WebMar 21, 2024 · The visible surface of the Sun, the photosphere, is the layer below which the Sun becomes opaque to visible light. Ever-changing, it is not a solid surface. The movie opens with a full-disk view of the Sun in visible wavelengths. Then the filters are applied to small pie-shaped wedges of the Sun, starting with 170nm (pink), then 160nm (green ... 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.

WebThe solar photosphere has a lower metallicity of about 84% of that of the proto-Sun. The difference in metallicity causes higher condensation temperatures (by 10 K) for the gas of solar system composition. The 50% condensation temperatures give the volatility groupings for the elements with solar system abundances at 10-4 bar, as follows. WebPhotosphere.
