Step-by-step explanation:
globular cluster is group of stars that is curve trajectory of a galactic core,globular cluster are spherical in shape and they are formed in the Halo of galaxy, they have very high stellar densities in their centre.
dwarf irregular galaxy is also called di-galaxy, they are galaxy with high level of gas and low metallicity, One of the common example of this galaxy is the large Magellanic clouds, dwarf irregular galaxy can be sighted in the southern hemisphere.
Spiral galaxy which is also known as sipral nebula is one that has a central nucleos with an extend curved arm, which rotate around the center axis.spiral galaxy exhibit higher luminousity.
An irregular galaxy is one with no specific shape compare to other galaxy such as Spiral galaxy
