There are billions of Galaxies in the Universe. Some are very small with only a few million stars. While others could have as many as 400 billion stars, or even more. There are three kinds of Galaxies, Spiral, Elliptical, and Irregular. The only difference between the three is what shape they are.
The Local Group
There are billions of galaxies in our Universe. Most of these are clumped together in small groups. Our own galaxy which is called The Milky Way Galaxy lies within a group of galaxies that we call The Local Group.
The Local Group consists of about 30 galaxies. The three largest are The Andromeda Galaxy, The Milky Way Galaxy, and Triangulum.
A galaxy is a massive group of stars, star clusters, interstellar gas and dust, and dark matter which is all gravitationally bound together.
The Milky Way Isn’t Just A Candy Bar!
While there are, indeed, many truly astonishing facts about the night sky and its many celestial bodies, here are just a few to get you started:
1. The sun that brings us light and warmth, and makes life on earth possible, is just one member of the galaxy known as the Milky Way. In this galaxy, there are between 200-400 billion stars that are each as big as the sun or even bigger. The fact that there are so many larger and hotter stars in this immense galaxy is sure to astonish and amaze any curious little mind.
2. Not only is the Milky Way huge in and of itself, it is only one galaxy among tens of billions of other galaxies. Each of these immense galaxies contain billions of stars. What’s more, even though the Milky Way is quite huge, some of these other galaxies are even larger!
3. Even though the Milky Way is one of the smaller galaxies, it is still bigger than we can reasonably imagine. Let you kids know that if you had a really fast car that could travel at a speed of 5,000,800,000,000 miles in a year, it would still take a hundred thousand years to drive from one side of the Milky Way to the other.
4. The Milky Way is older than old! In fact, scientists believe that it is 14,000,000,000 (14 billion) years old.
