Catalogue of Galaxies and Clusters of Galaxies
Okay kiddo, imagine if you had a big box of different kinds of candy. Each kind of candy would be like a galaxy, and the whole box would be like the catalogue of galaxies. Now, imagine if you had many boxes of candy all together. Those boxes would be like clusters of galaxies.
Scientists have studied and catalogued many galaxies and clusters of galaxies in space. They use some special tools to study them, like big telescopes and computer programs. This helps them learn more about how the universe looks, how it works, and even how things change over time.
So, a catalogue of galaxies is a big list of all the different galaxies that scientists have studied and observed, while clusters of galaxies are groups of galaxies that are close to each other. And through studying all of these galaxies and clusters, scientists are able to learn more about the universe we live in.
