It really is. Also there are many planetary systems existing only in our galaxy!

There are nearly 40 planets of size of Jupiter and or bigger are observed - indirectly. They have also observed that young stars have dust disc surrounding its equator which could be responsible for formation of planets. This way it is thought that many stars would have planets and may be life on few of them!

This is what they think. According to my thinking all stars have planets. They are not formed with the star itself but are obtained when the star is passing through the cool materials cloud of supernova explosion, after may be few million years of explosion!

Many of these star have atleast one life bearing planet. There could be millions of stars having life in advance stage than ours! They visited us many times in past and left information for us to this regards. It is difficult to believe this but it is a fact!
