10 Interesting facts about the Sun

Sun is the thing on the sky which gives us light and warmth but it is also at the center of the Solar System. The light Sun emits is primary energy source for us.

1.) Colour of the Sun

Who would say that the original color of the Sun is yellow? Well you would be wrong, the true colour is white. The atmosphere changes the colour of the Sun so it appears to be yellow.

   

2.) Sun and oxygen

When we have fire burning on the Earth we need oxygen but Sun on the other hand does not need oxygen to create light or fire. Instead of oxygen Sun burns helium.

   

3.) The size of the Sun

Size of the Sun is not fixed – throughout the past Sun expanded which means what we see now is not the same what was in the past. Its magnetic field is at less than half of its strength compared to the minimum of 22 years ago. This caused the heliosphere to shrink which increases the cosmic radiation hitting the Earth.

   

4.) Sun´s life

Somebody might not now that Sun has a limited lifetime. It is currently halfway through its sequence stage (nuclear fusion reaction, fuses hydrogen into helium). The scientists estimate that the sun will expire in 4,6 to 6 billion years from now.

   

5.) Layers of Sun

The sun has many different layers: Core – the innermost layer and source of energy
Radiation zone -transports the energy from the core
Convection zone – thermal convection occurs as thermal columns carry hot material to the surface (photosphere) of the Sun.
Photosphere-sunspots – visible surface of the Sun
Chromosphere – thin layer present above the visible surface
Transition region
Corona -outer atmosphere of the Sun

   

6.) Radiation

When we sunbath or are getting a sun tan it is not the sun light which makes us brown it is the ultraviolet light. In certain occasion, clouds could not block the radiation

   

7.) Position

Sun is situated in in the galaxy called Milky Way. It circles the center of Milky Way that is located 26,000 light years away around every 225-250,000,000 years.

   

8.) What is it made of?

The Sun is a star. It is huge, glowing sphere of hot gas. Most of it is hydrogen (70%) and helium (about28%). Carbon, nitrogen and oxygen make up to 1,5% and the other 0,5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur. Gravity then pulls together the burning gases of the Sun and stars. Large amounts of energy are produced by the Sun and the stars mainly due to the burning gases inside them.

   

9.) Sun and races

Scientists believe that the ultraviolet light can be blamed for the growth of different races or skin colour variation on Earth.

The ultraviolet light can be used to sanitize water or textiles because of the light´s antiseptic effects.

   

10.) The Name

The English name comes from old English sunne and it related to south. The name in Germanic languages including the Old Frisian sunne, sonne, Old Saxon – sunna, old Dutch – sonne, modern Dutch – zon, High German –sunna, modern German – Sonne, old Norwegian – sunna and Gothic sunnō.
