The Sun

 

For thousands of years people have been looking at the sky and wondering what those objects are all about. The glittering stars and the Sun have always hid a certain amount of mystery and beauty.

For astronomers, the Sun is just a dying star. For everyone else, however, it is a huge burning ball that gives us light, warmth and life. So far so good.

But what really burns our Sun? It is a well-known fact that there is no air in the cosmos. Accordingly, there is no oxygen to burn. Our everyday experience tells us that burning is a sequence of exothermic chemical reactions between a fuel and an oxidant. However, this is not the only kind of reaction. The sun really burns – but there is a nuclear rather than a chemical reaction.

Our star burns hydrogen. And in huge quantities – a few hundred millionths of a second. Do not worry – it has enough fuel that will allow it to exist for another 5 billion years.

      Yup, I’m trying to put information here about science and Space which we often take as granted. Just as the Sun. Most people can talk with hours about mixing different kinds of food and spaces to make a fancy dish, but if they have to speak about our Star – the basic of Life they will be in silence.
      Thank for the comment! See you in a couple of months.

    The sun is a very fascinating star. Thank you for bringing to light about the sun and what makes it really burns. We definitely take for granted that the sun rise and the sun set every day and all the time. We do not pay attention to it until it is gone. Thank you for the gentle reminder that the sun is full of mystery and beauty.

      You are very welcome Ha

      The reason to make this website is to share all I have learned about the Universe with everyone. Because the most  people thinking Astronomy is for  Science only and don’t pay any attention about it. The truth though is, The Universe is full with magic and is accessible for everybody!

      Thanks for the comment!

    That’s cool. I never thought about the sun not having oxygen. Next time I hear someone say that fire needs oxygen, I’m going to say ‘What about the sun?”. Can’t wait to see the look on their face. I love your website, nice interesting articles. It’s amazing how little people know about the sun.

      Haha, yeah I did this a few months ago on out fire training course. And guess what- nobody knew how the Sun works actually. Is kinda of sad though, we own everything on that Star!

      Thank you Dave
