no, they divide the sky into constellations
They don't divide it just like a puzzle, th fifteen grouping of stars are galexys between th galaxies the is nothing so their not dividing the sky it's self they're grouping the different places also known as galaxies
Spiral Elliptical Irregular Galaxies is pattern used to divide the sky into star patterns
astronomers did
Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.
They used a method called "representative sampling" to obtain their estimate. The sky is divided into sections of equal size and the number of galaxies in one section are counted. The count from that one section is then multiplied by the total number of sections in the sky
That the galaxy is moving away from us.
It is possible that someday astronomers will measure all the distances of the 100 billion galaxies in the universe.
Galaxy morphological classification is a system used by astronomers to divide galaxies into groups based on their visual appearance.Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1936.he divided the galaxies into 1) elliptical galaxies2)Spiral galaxies3)Lenticular galaxiesSource:wikipedia
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

Billions. (rounded)
They were discovered by astronomers using telescopes.
