«Here comes the sun, doo doo doo doo, here comes the sun, and I say it's all right». Right? No matter what, it is a fact that the sun will continue to hang from the sky every morning and, if we are lucky enough, not a cloud will affect this spectacular vision. Lord and master of the solar system, the Sun formed about 4.6 billion years ago and its energy reaches us in the form of light that feeds the plants and determines the Earth's climate. However, as indispensable as it is for everything that takes place on our planet, we must be careful and do not stare at it directly or spend too much time getting tanned.
