How many stars are there in the universe? The answer will surprise you! #stars #sciencefacts
73Hello, everyone! Today I'm going to talk about a topic that fascinates me: how many stars are there in the universe? I know you must be thinking: but that's impossible to know! After all, the universe is infinite, right? Wrong! At least, not the universe that we can observe from here on Earth. Scientists are able to estimate the number of stars that exist in the visible part of the cosmos, the one whose light reaches us.
They use powerful telescopes and a lot of mathematics. They choose a specific area of the sky and count how many stars and galaxies they can see in it. Then, they extrapolate that number to the total volume of the observable universe, using some assumptions and formulas.
But what is the result of this crazy calculation? Get ready to be amazed: it is estimated that there are about six hundred sextillion stars in the observable universe! That's a six followed by twenty-three zeros!
