Final answer:
The Milky Way Galaxy is a spiral galaxy that contains billions of stars, including our Sun. It is just one small part of the much larger universe that consists of billions of other galaxies. There are still many unanswered questions about these galaxies and their composition.
Step-by-step explanation:
It is true that the Milky Way Galaxy is a galaxy. Our Sun is one of the billions of stars in this spiral galaxy. Because of its faint glowing appearance in the night sky, it gets its name from the Greek word galaxias, which means milky. It is known that the universe is made up of billions of galaxies, each of which has billions of stars. Despite its vastness, the Milky Way is only a small portion of the universe. Science is still working to better understand the Milky Way and other galaxies, and many questions regarding their composition, evolution, and dark matter content remain unsolved.
