What is Supernova?

In astronomy, we often hear the word “Supernova”. Let’s see, what actually a Supernova is?

 Supernova is an event where an explosion of a huge star takes place. These blasts produce some heavy material in the universe including some elements, like iron, which make up  planets. Not all stars become Supernova though.

So, there are two types of supernovae.

White Dwarfs

White Dwarfs is something with the size of our earth and with 8 times the mass of our sun. This explains how dense it is. With this high density, it pulls mass from the neighbouring mass, using its gravity. By taking in the mass, it reaches a level called “Chandrasekhar limit”. At this instant, the star becomes unstable and supernova takes place. In turn, it forms something called Neutron star.

Star Fusion

 It occurs when stars core’s fusion process runs out of fuel. They can briefly outshine entire galaxies and radiate more energy than our sun will, in its entire lifetime. Stars are high nuclear reactors producing energy by fusing hydrogen into helium. Running out of fuel is nothing but, running out of hydrogen. With this, the helium is fused into heavier elements and supernova takes place, adding enrich elements to space clouds of dust and gas, further interstellar diversity, and produce a shock wave that compresses clouds of gas to aid new star formation.

Ultimately these supernovae are responsible for Black-holes and Birth of new stars too…

  1. Lol… Yes he’s right.. That’s bucket head rightπŸ˜‚πŸ˜‚πŸ˜‚..
