Difference Between Galaxy and Universe
Galaxy
vs Universe
Galaxy, which can be called as a star cluster
or a star system, is a system that
is composed of stars, gas, asteroids, dust, and dark matter. A central force known
as a black hole holds all these together. The universe consists of Earth and
other celestial bodies in outer space. The solar system is part of the
universe.
A galaxy is part of the universe. The universe has a
wider concept than a galaxy as everything is included in it.
A galaxy ranges from giant, with trillions of stars, and
dwarf with millions of stars. These stars are known to move around the mass in
the center. There are many galaxies in outer space. Several theories state that
there are many galaxies in outer space that we are not aware of as they are
invisible.
When talking about the universe, it can be
composed of anything around
us. The Earth, energy, sky, galaxies, and everything that is seen around us
comes under the term “universe.”
“Galaxy” is a term that has been taken from the Greek
word “galaxias” that means “milk.” “Universe” is a word that has been derived
from an Old French word “univers” which has been derived from the Latin word
“universum” which means “turned into one.”
A galaxy comes in different
shapes and sizes. In general, a galaxy has been divided into elliptical,
spiral, barred spiral, and irregular.
As per the Big Bang
Theory, the universe is known to have expanded from an extremely hot and dense phase known as Planck
epoch. Ever since the Planck epoch, the universe has been expanding always. It
is said that the universe has an age of 13.75 billion years.

1.A galaxy is part of
the universe.
