Type Ia supernova
Okay kiddo, let me tell you about type Ia supernova. Imagine a big, round ball in space. This ball is called a star. Some stars are really huge and bright, and they shine in the night sky.
Now, stars are made up of gas and dust. They use their energy to give off heat and light, just like a light bulb in your room. But, all stars eventually run out of fuel and stop shining.
When a star runs out of fuel, something really cool or hot can happen. Depending on the size of the star, it can either shrink down into a tiny, dense ball, or it can explode with a huge blast of energy.
Type Ia supernova happens when a star that's about the size of our sun has run out of fuel and starts to shrink down into a really, really small ball.
But, there's a twist. Just before this happens, the star has a friend. This friend is another star that's also in space. As the first star shrinks down, its friend starts to steal gas from it. This gas is being transferred from one star to another.
At some point, enough gas has been stolen that the first star can't keep shrinking into a small ball anymore. It suddenly explodes with a really bright burst of light and energy in all directions.
These explosions are called type Ia supernova. They are really bright and can even be seen from far away galaxies. Scientists love studying these explosions because they can tell us more about how our universe works.
