Supernova
After a full night watching the stars .
I'm reminded of a great phenomenon .
Yup, its the supernova phenomenon .
Do you know what a supernova ?
Supernova is the explosion of a star in the galaxy that emits a very large energy .
This supernova event marked the end of a history of a star .
Which experienced a supernova star will appear very bright and even light can reach hundreds of millions times the original starlight .
The energy emitted by the supernova is very big .
Even the radiant energy emitted during the supernova occured within a few seconds just to equal the radiant energy of a star within a period  of millions to billions of years .
Supernova energy emitted can be calculated based on the properties of the radiation beam .
Ordinary supernova occur due to endless age of star .

When the nuclear material in the star's core has been exhausted, it willn't nuclear fusion reactions can occur which is a propenent of life of a star .
And when it can't be done this nuclear fusion, the star will will die and supernovae .

The impact of supernova is :
1. Produces Metal
2. Creating life in the universe
- supernova catapult certain elements into space . These elements are then transferred to other parts far from the exploded star .
Its assumed that the element or material is then joined to form a new star or planet even the wild universe .

There is one star who did a supernova in space every single second of life on earth . Only, to find stars that will perform the supernova is very difficult . Many factors affect the supernova observations .
