The type of star cluster that forms from tightly packed group of older stars is called “The Globular cluster.”
Globular cluster is known to contain large group of old stars that are tightly and closely packed accordingly in a symmetrical but spherical form.
<h2>Further Explanation</h2>
Globular clusters are the largest and most enormous star clusters, and are known to usually appear in roughly spherical forms.
Globular clusters are usually formed through molecules of giant cloud, or enormous masses of gas that form stars due to their collapse. Notably, globular clusters cannot form today as a result of the current limited availability of free gas compared to its abundance at the early stage of the universe.
Globular clusters are found to be the oldest objects existing in the Galaxy. Globular clusters are said to contain between hundreds of thousands and millions of stars, and are heavily distinguished among other clusters due to their old age uniformity.
The relative ages of elements in globular clusters ranges from 11 billion to 13 billion years after being determined by comparing stellar population of globular clusters with stellar evolutionary models.
It should be noted that they could be as young as 9 billion years old based on modern developed research models.
