Galaxies
The Sun and all the stars we see in the night sky belong to a great group of stars that travel through space together. Such a group is called a galaxy. The star group to which our system belongs is called the Milky Way or just the Galaxy. There are about 100,000.000,000 stars in the Galaxy, or about 20 stars for each human being on planet Earth. The Galaxy is like a huge disc with a bulge in the middle. The Galaxy is about 100,000 light years in diameter. This means that it takes a beam of light 100,000 years to travel from one edge of the disc to the other.
The Milky Way is not the only galaxy in space. In fact, there are thousands of millions. But most are too far from the Earth to be seen with the naked eye. On clear, dark nights a small number can be seen without a telescope. People can see the Andromeda landromida] galaxy, the Large and Small Magellanic ,mcq3lWhere will people go after theyve explored their own solar system? Experts say that travel to other galaxies will only be possible in huge quot;starshipsquot;. They will travel through space for hundreds or even thousands of years with many people on board.
Then, when a suitable planet is found, some of these people will stay there and begin a new life. Later, theyll build new starships and go further to investigate the universe.
