Heyaa folk,

Our galaxy "Milky Way" is too bug and large. Scientists still don't know the real length. On a basis of technique they have just taken out the estimation of its size.

=> Our galaxy is 10,000 light years big.


The technique which the scientists used is

=> The farther the star the dimmer it would be and the nearer the star the more bright it would be and on the basis of this technique 10,000 light years is the estimated length of our universe.
