Supernovas

What is a supernova?A supernova is a star that took hundreds and thousands of years to form and is about to end in an explosion called a supernova. As you may all know our sun is one of the stars in our galaxy? But don’t worry it doesn’t have a chance going supernova. Why? First of all, it does not have the enough mass a star needs to become a supernova and it’s also too young. If you compared the sun to one of the oldest stars, it would have a huge age gap. Since the sun is 4.5 billion years old and one of the oldest stars that ages 13.8 billion years old.

What is it made of?A star releases energy every day. But will eventually die and gases, dust and elements such as hydrogen, oxygen and iron will explode into the galaxy. The materials that went out of the star will outshine the entire galaxy in all directions (300,000km) a second.

Binary star systemA Binary Star System is one of the two types of supernovas. It contains two stars that orbit each other. One of the stars is a white dwarf. Which is a small or medium star running out of fuel and nearly at the end of its life? The gravitational force will pull particles out from the other star. Its gravitational force will increase the mass and density of both stars which will lead to a supernova.

Single starA single star can also go supernova. If the star has ten times the mass the amount of fuel the sun runs on. Its core will collapse and a huge amount of energy will create a supernova.

What Happens After a Supernova?After a supernova happens it may leave a black hole. A black hole is an object or region in space with intense gravitation from which light, etc. cannot escape. But supernovas aren’t always about destruction. They help many new wonders in the world. The materials that have exploded into the galaxy helps create new stars and planets to form.
