Why Do Supernova Explosions Happen?

Supernovae explosions are one of the most destructive events in the universe, and it can be difficult for amateur astronomers to understand why. 

There are many different theories that explain these explosions, and it may take a good astronomer months or even years to come up with a working model. It is widely accepted that supernovae produce high levels of energy (high temperatures) which flare up the gas surrounding the explosions, giving off highly charged particles in the form of radiation waves known as “cosmospheric X-rays.” They can also create very strong magnetic fields, allowing radio signals to be picked up by telescopes orbiting the Earth.

The reason that supernovae explosions can cause this much damage is that they occur at extremely close distances from the galaxy. 

From this distance, it would take just a fraction of a second for a light signal to reach our telescopes on Earth, so the effects of supernovae explosions on our nearby neighbors could be severe. When a supernovae explosion occurs near a galaxy like our own, there could be dramatic changes in both its atmosphere and its magnetic field, which could affect the orbits of satellites circling the field, as well as having a serious effect on any satellites currently in orbit around it.

The two most common types of supernovae explosions are those caused by white dwarf stars and black holes. 

A white dwarf star is similar to our own sun, with a mass about five times that of our planet. It consists of a ring of material surrounding a massive nuclear nucleus, with a solid interior. Because of its massive size, a white dwarf star can only be created when it reaches a maximum distance from the solar system, about eight to ten times the distance to the Sun.

Another type of supernovae is Type IA, which happens when a white dwarf star goes supernova very quickly. 

As it becomes bright, Type Ia white dwarfs (also known as brown dwarfs) produce plasma, which can reach a diameter of more than ten kilometers. These types of explosions are the most common after Type IIa. After the plasma has reached such a large diameter, it can collapse into a black hole, or an even larger “event horizon”. This can happen at any time.

Astronomers know a lot about white dwarfs. They have found them frequently forming with other smaller space debris, and sometimes they seem to go together, or to remain separate. But there’s still much they don’t know. The biggest problem for scientists is determining how these explosions happen. Although astronomers know that the majority of these explosions are caused by a merger between two white dwarfs, they can’t explain why they happen in certain types of explosions.

Scientists use several different methods to study these explosions to learn more about them. One of these is a Very Large Telescope (VL telescope), but there’s also the European Southern Astromaster telescope. Both of these telescopes are designed specifically to see these rare events. One of the most popular ways to observe these events is through gravitational satellites. These are satellites that orbit the earth around the sun.

When astronomers see these supernovae, they also sometimes get a view of the supernova explosion’s shock waves. 

These can be heard by radio astronomers by listening in on the radio broadcasts from these explosions. Astronomers also use optical telescopes like the Very Large Array (Subaru), radio telescopes like the Arecibo dish, and x-ray telescopes like the Swift telescope. Some of these instruments are in space, and others are on the ground observing these celestial bodies around us.

If astronomers do observe a supernova remnant, they can study it to learn more about the explosion itself. If a stellar explosion occurs, a supernova remnant can appear very similar to a normal supernova. But they don’t always do so, and if they do they can give astronomers a clearer image of what was going on at the time of the explosion. Knowing what we can learn about a supernova gives us a better understanding of these explosions, and of the larger universe in general.
