1. The Local Group is a group of galaxies that includes our Milky Way galaxy.2. Abell 2029 is an elliptical galaxy.3. We live in the Local Group.4. When clusters of galaxies group together, it is called a supercluster.5. There are approximately 100-200 galaxy clusters in the Virgo Supercluster.6. Groups of superclusters are called the Sloan Great Wall.7. We can see objects that are currently 46 billion light years away because the universe is expanding.

Explicación

## Step 1The Local Group is a group of galaxies that includes our Milky Way galaxy. It is a part of the Virgo Cluster, which is a part of the Virgo Supercluster.## Step 2Abell 2029 is a type of galaxy known as an elliptical galaxy. Elliptical galaxies are characterized by their elliptical shape and lack of spiral arms.## Step 3We live in the Local Group, which is a part of the Virgo Cluster, which is a part of the Virgo Supercluster.## Step 4When clusters of galaxies group together, it is called a supercluster.## Step 5The Virgo Supercluster contains approximately 100-200 galaxy clusters.## Step 6Groups of superclusters are called the Sloan Great Wall. If they are linear, they are called filaments, and if they are planar, they are called walls.## Step 7We can see objects that are currently 46 billion light years away because the universe is expanding. This expansion causes the light from these objects to take longer to reach us, allowing us to see them as they were 13.8 billion years ago.
