I love to look at the stars at night. 
I love stars.  So many are visible to the naked eye from Earth.
That is what is so cool. everyone can see the stars.
Most stars in the Universe, including all of them outside of our galaxy, are invisible to the naked eye!
I did not know that. that is cool. there is a place where there is not light to look at the stars
It is easier to see them from dark places rather than any place with city lights.  However, most stars are invisible from Earth, even using the most powerful telescopes!
are those from other galaxies?
Yes.  For the most part.  The nearest star to Earth is our sun!
