The Milky Way is around 120,000 light years across.

About The Milky Way

The Milky way is our galaxy and is spiral. The sun happens to be one of 200 million stars in the Milky Way. It is also one galaxy out of just 100 billion in the universe. The Milky Way has a flat disk with a bulge in the center. There is a spinning motion that occurs at the speed of hundreds of kilometers per second. Which causes matter from in the disk to have a certain spiral like shape.

More information on Galaxies

Galaxies are systems in space that are formed out of gas, dust, and so many stars. Galaxies are divided up into three main types. They are spiral galaxies, elliptical galaxies, and irregular galaxies. Some astronomers think that galaxies were created after a cosmic happened to the universe from 10 to 20 billion years ago. After the explosion had occurred clouds of gases had began to collapse and were forced under gravity and started the form of the galaxies. There are some scientists who say small groups of around one million stars, which is known as globular clusters, then formed into galaxies later on. Then others say galaxies were formed first, then the stars later on had gathered into small clusters.

A Similar galaxy called Messier 81

Messier 81

This is a picture of of the Messier 81. Another galaxy similar to the Milky Way, which is also known as a spiral galaxy too. It is the brightest of the galaxies through telescope on earth. Astronomers call is a "grand design" and it's arms curl down to the center. It is 12 million light- years away. It is located in the Ursa Major Constellation.
