Looking at Globular Clusters
Globular clusters are defined as a dense grouping of thousands to millions of stars. They are comprised of young stars at millions of years old to older stars at billions of years old. The stars in these clusters are usually very tightly bound together.
They are ... Optical Features of Telescopes

The History of Astronomy
If you have a passion for star gazing, telescopes, the Hubble and the universe and this thing we call “astronomy”, you are far from alone. Of course, we know that astronomy is a highly respected science that has produced some of the most amazing accomplishments of the twentieth ...
The Universe through a Child’s Eyes
