The retina receives light and contains cells called cones that are responsible for detecting color. The cones are sensitive to different wavelengths of light, allowing us to perceive color.
The planet that gives off its own heat and light is Earth. It receives light from the Sun and reflects some of it back into space. Earth also generates heat internally from radioactive decay and geothermal processes.
The central part of the shadow or umbra is darker because it receives no direct light from the source of illumination. In contrast, the penumbra receives some light due to partial obstruction, resulting in a less pronounced shadow.
Venus receives about 2/3 of the sunlight that Earth receives due to its closer proximity to the Sun. Despite being closer, Venus's thick atmosphere reflects a significant amount of sunlight, limiting the actual amount of light that reaches its surface.
Yes, Mars receives about half the amount of sunlight that Earth does due to its greater distance from the sun. Additionally, Mars has a thinner atmosphere that scatters and absorbs some of the sunlight that reaches the surface, further reducing the amount of light that reaches the ground.

No part of the Earth receives the same amount of light every day, but every point on Earth receives the same amount of light in a whole year.
The Moon reflects PART of the light it receives from the Sun. And part of this reflected light is seen by us, here on Earth.
The equator.
Earth receives a constant supply of sunlight and cosmic radiation from outer space. Additionally, Earth also receives a continuous influx of meteoroids and dust particles from the solar system.
The region of the earth that receives the most sunlight year-round is around the Tropic of Capricorn. The earth receives the sun's direct light making the tropics warmer than the poles.

The north and south poles
The part of the moon that is always in sunlight is the "near side" of the moon, which faces Earth and receives light from the sun. This is the side that we see from Earth, as the moon rotates at the same rate that it orbits Earth, keeping the same side facing us.
The Earth receives the most energy from the Sun from the photosphere, which is the visible surface of the Sun. This layer is where most of the Sun's radiation, including light and heat, is emitted.
No, the earth and moon do not generate their own light and heat. The Earth receives light and heat from the Sun, while the Moon reflects light from the Sun.
