Edwin Powell Hubble, the American astronomer, demonstrated the existence of other galaxies besides the Milky Way.
Observations show that all galaxies are moving away from each other and those which are furthest away are moving fastest.

what is the type of star used by the Hubble to measure the distance to other galaxies.
It showed that most gamma ray bursts come from other galaxies, not our own. This means that gamma ray bursts must be extremely powerful.
The universe has not existed in the same state for an infinite amount of time, that would be the steady state theory, which has been replaced by the big bang theory. The galaxies are moving away from each other because the universe is expanding at an increasing rate. It has been expanding since the big bang happened 13.7 billion years ago.
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
