Hubble Observatory photographed the heart of a globular cluster

The Hubble mission support team has published a new image obtained by the space observatory. It demonstrates the center of the Terzan 4 globular cluster.

The Terzan 4 cluster is located in the direction of the constellation Scorpius. It is a group of closely gravitationally bound stars that orbit the galactic center as a single satellite. Most similar structures are characterized by a very solid age, which is close to the age of the first galaxies formed shortly after the Big Bang.

Hubble has revolutionized the study of globular clusters. The fact is that due to the dense “packing”, it is extremely difficult for ground-based telescopes to distinguish individual stars in their centers. The task is also complicated by gas and dust clouds, the concentration of which is especially high near the center of the Milky Way. 

It was only after Hubble’s launch that astronomers finally had the opportunity to study globular clusters in detail. Its technical capabilities allowed to determine the age of their stellar population with an accuracy of up to a billion years, which allowed us to shed light on the history of the appearance and evolution of such formations.

Recall that Hubble recently photographed stars spiraling into the center of the Small Magellanic Cloud.
