Did you know that the sunlight hitting the earth right now is 30 thousand years old :O
The energy in the sunlight we see today started out in the core of the
Sun 30,000 years ago – it spent most of this time passing through the
dense atoms that make the sun and just 8 minutes to reach us once it had
left the Sun! The temperature at the core of the sun is 13,600,000
kelvins. All of the energy produced by fusion in the core must travel
through many successive layers to the solar photosphere before it
escapes into space as sunlight or kinetic energy of particles.
