Supernova

By: AJ D.

What is it?

Supernovas are a type of exploding star in space. Every supernova is about one billion times brighter than the sun. The explosion from the star then fades aways after the explosion. These explosions are very bad to see due to the fact you will go blind instantly, and if you are close enough, you might be obliterated by the explosion. However, the after effect of the explosion is beautiful.

How Supernovas begin.

Supernovas are formed when a certain type of star called a red giant can no longer burn fuel. This process begins when the star runs out of usable gases to burn off of. Then, the star begins burning off of metals such as carbon and iron. At this stage, the star only has days to live. The star can't live off these metals and the star begins to explode. This explosion is a Supernova.

How Supernovas can create.

Supernovas are a very dangerous thing, but they also have the power to create. After a Supernova, matter from them flies through space which then attaches itself to different types of space dust and gases which then expand and create a star. In fact, a Supernova in the milky way galaxy created Earth! Supernovas are also continuing to expand through space and are creating different elements in space.

How dangerous Supernovas can be.

Supernovas are really beautiful, yet they are classified as one of the most violent events in the universe. These events begin with a blinding flash, then a wave of gamma radiation and heat comes through and destroys everything in its path. Not only that, they happen frequently in the universe. About every 50 years, there is a Supernova in just the Milky Way galaxy alone! These events are very, very dangerous.

Conclusion

As you can see, Supernovas are one of the most complex and detailed events in all of the universe. A Supernova will eventually happen to all red giants in the universe, including our own Sun. Because the universe is constantly changing, there is always going to be Supernovas in the universe. Thank you.
