Abell catalogue
The Abell Catalogue is like a big book of galaxies that astronomers use to find and study space things. It's kind of like looking at a bunch of pictures in a photo album, except instead of pictures of people, it's pictures of galaxies and clusters of galaxies.
Scientists named George O. Abell made the catalogue by looking at pictures of space taken by telescopes. He found over 4,000 clusters of galaxies and made a list of them in his book. The clusters are numbered with the name "Abell" and a number, like "Abell 1060."
Each cluster has its own description, including how big and far away it is, how bright it is, and how many galaxies are in it. Scientists can use this information to learn more about the universe and how it works.
Basically, the Abell Catalogue is a very helpful tool that astronomers use to understand and explore our universe.
