This is a picture of a luminous cluster. This cluster is called the Laniakea Cluster. It contains 100,000 galaxies, each galaxy containing billions of stars.
The small red dot is the location of our galaxy, the Milky Way, which contains 300 billion stars. One of these stars is the sun that shines on us every morning.
There are 10 million clusters in the universe like the Laniakea cluster, these 10 million are the cosmic clusters that scientists could only see, which means that there are millions and perhaps billions of other clusters that they did not see.
Imagine that the planet Earth and everyone on it falls within one of these points. Imagine that all people, with their countries, mountains, rivers, problems, wars, conflicts, races and anxieties, fall within one of these points
