What makes Sun and Moon Shine?
● The Sun shines with its energy. The light you see (and feel as heat) is given
off by the Sun’s surface, called the photosphere.
● Photosphere which is several hundred miles thick and composed of ever-
changing gases. Some of the energy the Sun produces must escape, or it would
build-up and explode.
● Whenever you see the Sun shining, you’ll know it’s just releasing excess energy
and giving us a little light and warmth in the bargain.
● Remember, you should never look directly at the Sun. The light is too bright for
our eyes to take.
● The Moon gives off no light of its own but reflects sunlight from its rocky surface.
What we call moonshine is sunshine reflected by the Moon.
