Sun

If you believe the whole staring at the sun makes you go blind thing, you are probably not doing a whole lot of sun gazing. But it’s a real marvel. The sun warms our planet every day, provides light by which we see and it is necessary for whole life on the Earth. It can also cause cell death and make us blind. It could fit 1.3 millions Earth inside its sphere. It has as much energy as 1 trillion megaton bombs every second. So you can guess that how much energy it has.  

Sun is nothing but it is a just star, by universal standard. It’s really just proximity that makes it so special on Earth. Without Sun our life can’t be exist.

There are some questions will arise in your mind, like…

·         How close is the sun?

·         How much space it take to hold 1.3 million Earths?

·         How does it burn?

·         Why does Sun send out solar flares?

·         Will the Sun ever stop burning?

·         If yes, then When?

·         And What will happen to Earth and its inhabitants?

In this blog we will look around all above questions.

The Sun has burned for more than 4.5 billion years. Its massive collection of gas are mostly Hydrogen and Helium. It has immense gravity and enough gravitational force to hold Hydrogen and Helium together. Here we says that Sun burns, but it doesn’t burn like wood. Instead the Sun is gigantic nuclear reactor.

The Sun is a star, just like a other stars we see at night. The main difference is light year. Light year is unit of measurement for very far distances. It is distance that light travel in year. Our Sun is only 8 light minutes away from Earth.

The Parts of the Sun

The Sun is classified as a G2 type star. Based on its temperature and wavelengths or spectrum of lights that emits. There are so many G2s out there.

The sun is composed ofgas. It has no solid surface. It still has defined structure. The tree major areas of the sun are listed below:

1.       Core: The center of the sun comprising 25% of its radius.

2.       Radiative Zone: The section immediately surrounding the core, comprising 45% of its radius.

3.       Convective Zone: The outer most ring of the sun, comprising 30% of its radius.

The atmosphere of the sun is divided in three parts:

v  Photosphere: The innermost part of the sun. This is part only we can see.

v  Chromosphere: The area between photosphere and corona. It is hotter than photosphere.

v  Corona: The extremely hot outmost layer, extending outward several million miles from chromosphere.
