Cloud and Dust galaxy
No wonder that everyone in this world looks at the sky and starts thinking " How many stars might be out there?" It is a fact that there are much more stars out there in the sky than there are grains  of sands here on 
Earth. Now think!!

Out there in the Galaxy which is a huge group of stars they are all held together by the gravity .Some galaxy are eliptical  some are spiral. Among them yet Milky Way galaxy is discovered largest galaxy. Some  hypothesis states that Milky Way galaxy is 100,000 light years from one end to another and let me tell you one light year is the distance travelled by light in 1 year with the velocity
 of 300,000 km/s. It is eatimated to have 4 billion of stars. It is still likely to see 2500 stars at a time as per angle of our eye. Others are impossible to see from earth without telescope. Containing around 4 billion of stars  is our Milky Way galaxy and it is only one. There are more such galaxies out their than you can imagine.There are 40 galaxies  just in local
Spiral galaxy
 group and after that there are lots of them. The nearest one from us is Andromeda Galaxy which is 4.6 light years away.
