Animated explanation of the temperature of the Photosphere (University of South Wales).This is due to the convection of gases from deep within the solar interior.
It is much cooler than the core The photosphere is the lowest layer of the. Close observation reveals the photosphere to be granulated. Animated explanation of the Photosphere (University of South Wales). The photosphere is the layer that we see when we look directly (foolishly) at the Sun. Spectacular loops and prominences are often visible on the Suns limb (left). A total eclipse happens when the Moon passes in front of the Sun and blocks out the bright light from the photosphere.Media related to Photosphere at Wikimedia Commons Several methods of measuring the temperature have all determined that the Sun's photosphere has a temperature of about 5,840 K.The term photosphere means 'sphere of light' and is the layer where most of the sun's.

Most of the Suns visible light that we see originates from this region. "Whole Earth Telescope observations of BPM 37093: A seismological test of crystallization theory in white dwarfs". These features are too fine to be directly observed on other stars however, sunspots have been indirectly observed, in which case they are referred to as starspots. Other magnetically-related phenomena in the Sun's photosphere include sunspots and solar faculae dispersed between granules. Grouping the typical granules are supergranules up to 30,000 kilometers (19,000 mi) in diameter with lifespans of up to 24 hours and flow speeds of about 500 meters per second (1,600 ft/s), carrying magnetic field bundles to the edges of the cells. Each granule has a lifespan of only about twenty minutes, resulting in a continually shifting "boiling" pattern. In the Sun's photosphere, the most ubiquitous phenomena are granules- convection cells of plasma each approximately 1,000 kilometers (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 kilometers per second (4.3 mi/s).
