Answer:
Explanation
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems.
-We are in the Milky Way Galaxy . The Milky Way is shaped like a huge whirlpool that rotates once every 200 million years. It is made up of at least 100 billion stars, as well as dust and gas. It is so big that light takes. 100 000 years to cross from one side to the other.
-There are many galaxies besides ours, though. There are so many, we can’t even count them all yet! The Hubble Space Telescope looked at a small patch of space for 12 days and found 10,000 galaxies, of all sizes, shapes, and colors.
