An image from the NASA/ESA Hubble Space Telescope apprehends the sparkling globular cluster named NGC 6569 in the constellation -Sagittarius. Hubble examined the heart of this cluster with both its Wide Field Camera 3 and Advanced Camera for Surveys, reflecting a gleaming pile of stars in this astronomical treasure trove.

Globular clusters are durable, tightly bound clusters including tens of thousands to millions of stars and are linked with all types of galaxies. The strong gravitational attraction of these compact clusters of stars implies that globular clusters have a regular rounded shape with a densely occupied center.

These observations are found from an analysis of globular clusters which exist close to the heart of the Milky Way. Earlier surveys avoided these objects, as the dusty center of our galaxy obstructs their light and modifies the colors of the stars residing in them. A star’s color is extremely important for astronomers studying stellar evolution and can provide astronomers with insights into their ages, compositions, and temperatures.

The astronomers who formulated these observations combined data from Hubble with information from astronomical archives, enabling them to measure the ages of globular clusters, including NGC 6569. Their study also delivered insights into the structure and density of globular clusters at the heart of the Milky Way.
