What are galaxies?
Galaxies are large systems of stars, gas, and dust that are held together by gravity. They come in different shapes and sizes, ranging from spiral galaxies to elliptical galaxies to irregular galaxies.
How are galaxies formed?
Galaxies are believed to have formed from the gravitational collapse of smaller structures, such as gas clouds and dark matter. As these structures pulled in more matter, they eventually formed stars and galaxies.
What is the Milky Way?
The Milky Way is the galaxy that contains our solar system. It is a barred spiral galaxy, meaning it has a central bar-shaped structure with spiral arms extending outwards. It is estimated to be about 100,000 light-years in diameter.
How many galaxies are there in the universe?
It is estimated that there are billions of galaxies in the universe. The exact number is difficult to determine, but current observations suggest that there may be as many as 100 billion to 200 billion galaxies.
