Pulling then down for you
Ah... the night sky. Beautiful isn't it? Just the way that the stars twinkle, all of the different colors and sizes. It's amazing how far they can be and how far the light can reach, makes you wonder if they really are the way we see them.
There is where stellar variability comes in
It sounds really cool but... what is stellar? is everything related to stars. And a star? a star is a celestial object that makes light on its own! they are the beginning of all the visible light that we can perceive from the universe and they can allow us to understand a lot about the universe we live in.
Now what is stellar variability, it is basically the change in the brightness that we can perceive from the stars from all the universe around, how they change between days and even years! the process is beautiful and magnificent to the human eye even though we can not perceive everything from this light that we get, but no worries, we got the science on our side that help us appreciate and even better understand why this happens and let us predict the future with multiple benefits
