WebA chromosphere ("sphere of color") is the second layer of a star's atmosphere, located above the photosphere and below the solar transition region and corona. The term … Webthe temperature in the chromosphere is within a factor of 2 to that in the photosphere, the scale height of chromospheric gas is roughly the same as that of photospheric gas. In a simple 1D representation, the temperature above the chromosphere first jumps to more than a million Kelvin just within a 100 km thick layer called the WebThe Sun’s visible surface the photosphere is “only” about 5,800 K (10,000 degrees F). Just above the photosphere is a thin layer called the chromosphere. The name chromosphere is derived from the word chromos, the Greek word for color. It can be detected in red hydrogen-alpha light meaning that it appears bright red. datenrettung andreas wach
