Sir blue star means newly formed and according to wavelength they are near to earth. Red colour stars means a greater distance. The earth has a very large distance from irregular galaxy, so these stars must appear in red colour because they are far away and they emit red wavelength..
Is it so sir?

In no rotational galaxies, exoplanets would still revolve around there stars even though there is no rotation of the stars themselves?
