How many galaxies are there in the universe?

Kids ASK! about Science & Technology

There are billions of galaxies in the universe! Each galaxy consists of stars, gas and dust held together by gravity. The galaxy that we are living in is called the Milky Way and it is just one of the billions of galaxies in the universe.

Scientists have predicted that our galaxy, the Milky Way, has about 400 billion stars. Therefore, our solar system is only a tiny part of the Milky Way.

Just imagine – if you are given a chance to travel beyond the Milky Way, how does our Milky Way look like? It will probably look like a gigantic pinwheel with a bright center and a thin disk of stars spiraling outward. Our solar system will only look like a tiny, almost invisible speck.
