Webb5 mars 2024 · The sunspots are caused by the sun's magnetic fields. The photosphere is one of the most visible layers of the sun from the surface of the earth. There is a temperature of around 10,000 °F (5,538 °C) in this area. Light and heat are sent to Earth through this layer, which resembles a bright disc.
WebbUnder normal circumstances, the bright yellow surface of the sun, called the photosphere, is the only feature we can observe. But during an eclipse, the moon blocks out that intense light, allowing scientists to observe the much dimmer solar atmosphere. Our 2024 eclipse brochure has a composite image of the sun on the back. WebbLa photosphère est la couche de gaz qui constitue la surface visible des étoiles, en particulier du Soleil, et où se forment la plupart des raies spectrales depuis l' ultraviolet jusqu'à l' infrarouge.

Webb21 mars 2024 · Particles of light form from atoms undergoing nuclear fusion in the sun’s innermost layer known as the core. The light then flows through the sun’s interior for millennia, slowly bubbling up like water in a boiling pot. It eventually bursts past the sun’s surface, called the photosphere, and rises into the solar atmosphere. The photosphere is a star's outer shell from which light is radiated. The term itself is derived from Ancient Greek roots, φῶς, φωτός/phos, photos meaning "light" and σφαῖρα/sphaira meaning "sphere", in reference to it being a spherical surface that is perceived to emit light.
