on 10/12 i have an IQtest.. if u want to go to mrsm... u must past this test.. so i'm having a revision right now.. n i found some interesting facts about sun.. n it really help me to remember back about science.. i know it seriously boring.. but i really need this info n i really want to share it with u.. :) ignore the grammar again.. :)
The sun is the brightest star which we know of and we have learnt that the sun is made up of different gasses which fuse within themselves and give away huge amounts of energy. This energy is what we receive as sun-light which is vital for existence of all types of species namely plants, animals and human beings and responsible for day/night, time sense etc. When we observe the sun wearing coolers during a solar eclipse, what we see surrounding the dark sun is the corona of the sun which is an uneven glow of rays emitting outward from the sun.
To get a better understanding about the corona, we first need to understand a little bit more in detail about the composition of the sun. We all know that the earth’s surface is made up of solids and even beneath the seas, there is a slid layer. But the suns surface is not a solid like the earth. The surface of the sun, which is what is visible to our naked eyes is made up of gasses as we had mentioned earlier. Scientists believe that the sun is made up of four layers of various gaseous matter on the outside which completely hides what the sun is made of beneath these four layers. Scientists have named these four layers, the innermost layer being termed as photosphere, the next two layers called as reversing layer and chromosphere. These three inner layers form the atmosphere of the sun. The outermost and the fourth layer are what we known as the corona of the sun.
The photosphere or otherwise termed as the ‘light sphere’ is the layer which we look at when we look up at the sun. Many a times, dark spots can be observed on this illuminated, brightly glowing surface. The nest layer, the reversing layer is a gaseous layer made up of gaseous vapours and spreads to hundreds of miles, away from the photosphere of the sun. This layer is not visible to naked eye but with the help of a device known as spectrograph, this ‘reversing layer’ can be studied.
The chromosphere which is commonly known as color sphere is a layer which extends to about nine thousand miles and comprises of helium and hydrogen gases. During a total eclipse, we have observed a brilliant scarlet light which shines surrounding the dark disc. From this border, huge flames of colored clouds which comprises of the same material, shoot out outside like great dancing flames of fire, extending at times to even one million miles. This is what is known as prominences.
surrounding this layer is the corona which itself is divided into two layers known as the inner and outer corona. The inner corona next to the chromosphere is a thin pale band of yellow. The outer corona is a white surface which has streamers that extend upto millions of miles originating from the edge of the sun. This is what the scientists of our times have discovered about the outer layers of the sun. What lies under these layers is still a puzzle which is yet to be solved.
