This rich and dense star splinter is a massive globular cluster, a gravitational cluster of stars orbiting the Milky Way, according to a statement by the US Space Agency.
Globular clusters are denser and more spherical than open star clusters like the famous Pleiades. They usually contain hundreds of thousands of stars, which are believed to have formed at about the same time.
It is believed that hundreds of thousands of stars were formed within the NGC 6139 over 10 billion years ago, the report said.
As a result, they contain some of the oldest stars in our galaxy that formed very early in the galaxy's history.
Their role in galactic evolution, however, is still a matter of study.
This cluster is seen approximately towards the center of the Milky Way in the constellation Scorpius (the Scorpion).
This constellation is a goldmine of fascinating astronomical objects.
Astronomers have used Hubble multiple times to observe "Scorpius" to observe objects such as the butterfly nebula, surprising binary star systems, and other dazzling globular clusters, the report said.
Earlier this month, Hubble also unveiled the most comprehensive high-resolution ultraviolet light measurements of near star-forming galaxies.
