Photosphere: Photosphere is a star's outer
shell from which light is radiated.
Temperatures in the Photosphere range from 11,000 F(6,125 C)
at bottom to 7,460 F(4,125 C) at top.
Elemental abundances in the Photosphere are well known from spectroscopic studies,
but the composition of the interior of the Sun is more poorly understood.
Looking directly at the Photosphere of the Sun(the bright disk of the Sun itself), even for just a few seconds, can cause permanent damage to the retina of the eye,
because of the intense visible and invisible radiation that the Photosphere emits.
An eclipse when the Moon is near its closest distance from the Earth(that is, near its perigee) can be a total eclipse because the Moon will appear to be large enough to
cover completely the Sun's bright disk, or Photosphere; a total eclipse has a magnitude greater than 1.
