What will sun made after explosion
Answers
Explanation:
Dr Chris Manser, a postdoctoral researcher in astrophysics at the University of Warwick, answers this important question posed by a 12 year old.
The sun is a star, and when a star explodes it’s called a supernova. These types of explosions are very bright, and very powerful. They release lots of dust into space, which is used to make more stars and planets. Our solar system was made using stuff from these explosions. Even humans are made of star stuff!
If the sun suddenly exploded like this, the whole solar system would be destroyed. You don’t have to worry though – only stars ten times the size of our sun, or bigger, can explode like this. Our sun will end its life in a different way.
A supernova is like bursting a balloon. But when our sun dies, it will happen slowly, like when you gradually let the air out of a balloon.
The death of the sun
The sun will start to die when it runs out of fuel in about 5,000,000,000 years (that’s five billion years). This is 77 times longer than the Tyrannosaurus-Rex has been extinct … a very, very long time.
When the sun starts to die, it will get bigger and slightly colder, turning into what astronomers call a “red giant”. It will get so big, that it will eat Mercury, Venus and even Earth.
When the sun is a red giant, it will be big and puffy, and start to blow off its outer layers out of the solar system. It will get smaller and smaller, eventually becoming what we then call a white dwarf.
Explanation:
The sun will become the red giant and then a white dwarf over billions of years. This is a very long time. We cannot watch a star do all of this but we can learn how stars are born and die by looking at the stars in our galaxy
