STAR CLUSTERS

Star clusters are both the youngest and oldest easily recognisable objects in the Galaxy. Globular clusters, like the magnificent southern naked-eye cluster 47 Tucanae (alongside) are the oldest star clusters known, with ages comparable with the age of the Universe itself. In contrast, young clusters such as NGC 3292 (AAT 10) are just a few million years old, brash newcomers in the Milky Way, and still associated with the gas and dust from which they have so recently formed. It is by study collections of stars such as these that astronomers can unravel the the complex story of stellar evolution.
