Ответ:

Would you like to travel in space? If so, you have to choose where to? It is difficult to imagine that there are about 20 stars for each human being on our planet. A group of stars is called a galaxy. It will take of you  100,000 years to travel from one edge of it to the other. But people hope they will travel through spase on huge starships far from the Earth.
