   Photosphere
   The visible surface of the Sun. It consists of a zone in which the gaseous layers change from being completely opaque to radiation to being transparent. It is the layer from which the light we actually see (with the human eye) is emitted.

    Photosphere
    The `photosphere` of an astronomical object is the region from which externally received light comes. It extends into a star's surface until the gas becomes opaque, equivalent to an optical depth of 2 or 3. In other words, the photosphere is the region where an object stops being transparent to ordinary light.

    photosphere
    The visible surface of the Sun or some other star; it lies just below the chromosphere and just above the convective zone and has a temperature of about 6,000 K. The photosphere ends (and the chromosphere begins) at about the place where the density of negative hydrogen ions falls too low to result ...
