The Sun

I think that one of my favorite photo is one about the main stars of our galaxy, I am talking about the sun ; with the new  technologies we can know how it is and how it works. The sun is the star at the center of the Solar system and it has a diameter of about 1,392,000 km.

The distance that we are from the sun is about 149.600.000 kilometers and the sun’s shine travels to the earth about only in eight minutes.

Its composition consists in three quarters in mass of hydrogen, and the rest is mostly helium. Less than 2% consists of heavier elements, including oxygen, carbon, neon, iron, and others.

We can’t see the sun shine, for that reason was a mystery how the sun looks like when we didn’t have satellites or that kind of technologies. Despite of that, people have tried to study from the remote time; one of the most famous persons who studied was Galileo Galilei who observed the sunspots in XVII but the Chinese and Babylonian astronomers have studied it yet. Many cultures in the past were interested in the sun because it gives us life.

So I think that this picture shows us not only how the sun looks like but also how small is our earth and the others planet that are rotating around the sun.

This photograf was taken by the Atmospheric Imaging Assembly of NASA's Solar Dynamics Observatory and it is one of the most closed photos that we know and we have ever seen about it.

The sun shine power supports all kind of life in the world through the photosynthesis and determines the climate of our planet.

For those many reason I think that this pictures is very important for the humanity because show us one of the greatest mystery of the universe that allows the life.
