Most scientists believe that inside the Sun one chemical element - hydrogen turns into another - helium. Hydrogen particles are combined into heavier particles, with this combination, energy is released in the form of light and heat.

The white color of snow is caused precisely by its structure. In ice, all crystals are strictly aligned and oriented. Light, therefore, passes through ice with only a slight change in direction. Snow, on the other hand, has ice crystals arranged randomly. As a result, light falling on one of them, in a refracted form, falls on the other, which again changes its direction. Moreover, snowflakes are even capable of decomposing white light into color spectral components - but as a result, all this gives exactly white color.

Terminator (from lat. terminare - to stop) - a line of light separation that separates the illuminated (light) part of the body (for example, the cosmic body) from the unlit (dark) part. The terminator of a spherical body is always observed as a semi-ellipse, taking the form of a straight line at the end of the first and the beginning of the last quarters.
