The Universe is the whole thing, while a galaxy is only a part and there are billions of galaxies in the Universe.
universe consists of many galaxies
(astronomy) a collection of star systems; any of the billions of systems each having many stars and nebulae and dust is known as galaxy
Everything that exists anywhere is known as universe
ex:"they study the evolution of the universe"
A 'galaxy' is a collection of stars and planets in one space orbiting a core or a very large star. The 'universe' holds all these Galaxy's and could be infinite.
E.g. We live in one of millions of Galaxy's but all the Galaxy's live in one universe.
(the best way I can explain it in typing.)
The Universe Is the whole, where all the galaxies are, and galaxies are just big clusters of starts, planets and different types of debris.
The Universe contains the galaxy's which contain the solar systems which contain the planets and stars.
A galaxy is made up of solar systems and a solar system is just a part of a galaxy. Our solar system is just a dot in the Milky Way galaxy.
The Universe is defined as "Everything", and includes several billion galaxies.
I donβt know
Universe -> galaxy -> star -> planet
expansion difference
In the galaxy, we are in one of the spiral arms. We do not know where we are in the Universe.
Universe, galaxy,nebula,solar system, star, planet
They are in all three. Planets are in solar systems. There are lots of solar systems in a galaxy. There are lots of galaxies in the universe. So any planet is in a solar system, a galaxy and the universe.
A galaxy contains billions of stars. A universe contains billions of galaxies.
A solar system is a single star in this case the SunA galaxy is an area in the universeA universe is every thing.
The Universe is everything, as far as we know. A galaxy is just a collection of stars. A galaxy is huge - typically about 100,000 light-years across - but the visible Universe contains hundreds of billions of galaxies.
Universe -> galaxy -> star -> planet
The Universe Is the whole, where all the galaxies are, and galaxies are just big clusters of starts, planets and different types of debris.
the universe is bigger than the galaxy because our galaxy (the milky way) is in the universe.
there is no difference. they are both 42.
Actually a galaxy is in a universe
A satellite galaxy is one that revolves around another galaxy.
A galaxy is a tine part of the universe.
A star is one, a galaxy is many.
