How a star takes birth in the universe?
Are all stars the same?..and many more questions...
If all these questions arrives in your mind then this article is for your...read this till end





Let's start from the beginning...


The star formation

The star formation is a complex process,before knowing this process you should know about Nebula. 
Nebula are the vast clouds have mainly Hydrogen,helium and Dust

1.The beginning of the star formation is with the vast clouds also called as Nebula.In these clouds there mainly three things hydrogen,helium and dust.Scientist pretends only these three things,apart from these three things there would be more elements or objects takes place in the formation of this clouds.

2.When all these clouds are in ready for the formation of the star,then all the fragments of these clouds are shrinked up.These clouds are shrinked to get "Protostars".Protostars are the first stage of star's life.

3.When the protostars are ready to take position.There are may nuclear reaction takes place at the center of the protostars(core).All these nuclear reactions are also pretend by the scientist and astronomers.They found that the protostars after some time becomes very hot and shines.These nuclear reaction are taken place in stars core to shine the star steadily.

4.After this the star is ready to shine.The end of the star's life is with a massive explosion also known as "supernova".When the star life is ended the star explode with a massive impact also known as Supernova.After the supernova the star left remnant as nuetron  star or a black hole.

Some basic general facts based on star and universe! 

  •  The closest star to the sun is "proxima centauri". The distance between them is 4.2 light years.
  • The temprature of the hottest star is 45,000 celcius (80,000F)
  •  The brightest night time star is "sirius" whose distance is 8.6 light years and the brightness scale is -1.44
  • There are 4 types of nebula seen from the astronomers as well as scientist they are
1.Ant nebula
2.Cat's eye nebula
3.Eskimo nebula
4.Helix nebula
  • All stars spin but most of them spin much faster . And the fastest star is Neutron star 
    The universe is bigger than you think...
The whole universe is unidentified..

                        WHAT'S INSIDE EVERY PLANET ?                    The solar system The theme has been a big question to the public  "what's inside every planet?" here we are gonna discuss about our main topic, as we have studied in our earlier classes that our planet Earth has four layers inside (figure). The above figure is just a prediction by the scientist,well no one knows what's inside our mother planet Earth. The scientist has also predicted the same for ever planet in our solar system,here we are going to discuss about the prediction of scientist for layers inside every planet. Starting with the first planet Mercury :as we know mercury is the nearest planet to the sun the layers predicted are;crust,mantle and core,it has three layers inside. After Mercury we have got Venus :it's a planet surrounded by volcanoes,craters and m...
