Galaxies

A galaxy is a collection of stars, clouds, gas and dust. These elements are scattered throughout space in various shapes and sizes.
There are different types of galaxies; spiral, elliptical, irregular, and peculiar.
All galaxies except the very closest ones are moving away from us.
Many clusters of galaxies are linked together in superclusters. In between the superclusters are giant voids where no galaxies are found. [VH] {SR} {GA}
