Hubble.
Edwin Hubble collected large amounts of data compiled from spectra of celestial objects,
and correlated those with other data that could be interpreted as indicating the objects'
distance from us.
The pattern that emerged can be interpreted to imply that
-- There are galaxies of stars that are distant from the galaxy in which we're located.
-- All of the distant galaxies, in every direction from us, are moving away from us.
-- The farther from us a distant galaxy already is, the faster it's moving away.
Hubble proved none of this. But that should not be held against him or his well
deserved reputation as a brilliant scientist, because none of these things ever
can be proven.
In terms of a popular phrase that I love to tweak whenever I can, each of these
statements is "just a theory".
What else can I help you with?
Who proved that other galaxies existed?
Galileo
Who proved that there are galaxies besides the milky way?
Hubble, in his studies of Nebulas which turned out to be galaxies.
What significance does Edwin hubble have to the world of science?
Edwin Hubble was an astronomer.He proved that there are a lot of other galaxies out there.He proved that those galaxies are moving away from us and the universe is expanding.
The scientist who proved the existence of galaxies other than the Milky Way was who?
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
Who is the 20th Century astronomer proved that the universe contained a multitude of galaxies that were moving away from the Milky Way?
william herschel
What are the two important discoveries Hubble made that proved other galaxies exist outside our own?
Hubble discovered that the nebulas were galaxies based on the powerful telescope at Mt Wilson. The second discoveries was the red shift relationship v=HD shows that the galaxies were outside our own galaxies definitely and quantitatively, using light sources in galaxies that were standard sources that could calibrate the distance.

How many galaxies are there in a typical cluster of galaxies?
Galaxy clusters typically have anywhere from 50 to 1,000 galaxies.
How many galaxies are spiral?
Approximately 60% of all galaxies are spiral

How are the centers of many spiral galaxies similar to many elliptical galaxies?
Both have a huge black hole at their center.
How many barred spiral galaxies there?
It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.
