The History of the Sun – Our Life Source!
What do you know about the sun?
Of course, we all know it’s hot, not to look at it directly, it provides us with vitamin D and makes you feel good, and can burn your skin if you’re not sensible enough to use sunscreen. But do you know what the sun really is, and how it came about?
You might be surprised to learn that the sun started its life as a star, and still remains one in theory today. It was formed around four and half billion years ago. Although it isn’t the oldest star in the universe, even at that grand old age, there were plenty of stars before it’s time which had gone supernova (an explosion that briefly outshines an entire galaxy.) When these older stars went supernova and turned into nebulae (cloud of dust, hydrogen, helium and other ionized gases), the sun was born and remains in orbit to this day.
The sun is a mixture of chemicals and is made up of hydrogen atoms. A chemical reaction occurs inside the big ball of fire we know as the sun, changing these hydrogen atoms into helium atoms creating energy. It is thought that the sun will use up all its hydrogen atoms at some point in the distant future, and the effects of that could be somewhat catastrophic. However we thankfully won’t need to think about that for some lifetimes to come.
Despite being born out of humble beginnings as a star, the sun is now arguably the brightest star in the sky, and certainly the hottest, at around 14 million degrees Celsius at the very centre, and 5000 degrees Celsius on the surface. As well as providing sunlight to make sure we’re not all walking around in darkness, the sun plays a vital part in human life. Plants and trees wouldn’t survive without sunlight, and we wouldn’t survive without the oxygen given off by trees and plants. This life-nurturing energy provided by the sun is made of photons, which are given off by the sun, travel down and hit earth, providing us with light and life.
Of course these days we’re also beginning to harness the power of the sun in different ways, such as to provide electricity for homes through solar power. This is a very environmentally-friendly and clean way to power homes, and is a growing trend. This means we leave much less of a mark on the earth from carbon emissions, and instead learn to make use of the huge amount of power the sun sends our way in new and innovative ways.
As you can see the sun isn’t just a big ball of fire in the sky, it actually has very important functions to carry out. Without the sun it wouldn’t just be dark, we wouldn’t thrive at all.
