Each photon hitting earth is thousands of years old as per science it is 50 million years old, we should be thankful to have unlimited source of lighting and from safe distance
How the sun produces light?
The Sun produces light by a nuclear reaction called fusion. As atoms of hydrogen combine to form helium, they produce vast amounts of heat and light. Sunlight appears white, but it contains a mixture of all the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
Sunlight is produced through nuclear reactions in the sun’s core. Originally born as energetic gamma rays, after billions of collisions with matter, this radiation reaches the surface and escapes into space.
Layers of the Sun?
Nucleus: The nucleus is the area where nuclear reactions occur (fusion of hydrogen atoms).
Radiative zone: The radiative zone is a region dense ionized gas bombarded by g rays from the fusion of protons in the nucleus. These g rays bounce off the gas are absorbed and then re-emitted as X-rays and UV radiation.
Convective zone: The convection zone carries the heart energy to the surface by convection. The gas energy to bring the Sun’s surface and returns to the bottom after losing their energy.
Photosphere: The photosphere to 160 km thick is only responsible for the emission of energy that bathes the planets, it is mottled granules.
Chromosphere: The chromosphere is a semi-transparent layer visible during eclipses. This is where the protrusions are formed. The spicules are those long jets of matter projected.
Crown: The corona is the outer atmosphere of the sun. It undulates and changes shape during emission of gas jets. It is the visible part of the Sun.
