This rich and dense star grip is a massive globular cluster, a gravitational collection of stars orbiting the Milky Way, said the US space agency in a statement.
Globular clusters are denser and more spherical than open star clusters like the famous Pleiades. They usually contain hundreds of thousands of stars that would have formed around the same time.
The hundreds of thousands of NGC 6139 stars would have been formed more than 10 billion years ago, the report says.
As a result, they contain some of the oldest stars of our galaxy, formed very early in the history of the galaxy.
However, their role in galactic evolution is still a subject of study.
This group is seen roughly in the direction of the center of the Milky Way, in the constellation Scorpio (Scorpio).
This constellation is a gold mine of fascinating astronomical objects.
Astronomers have used Hubble to track "Scorpius" many times to observe objects such as the butterfly nebula, startling binary star systems and other dazzling globular clusters, notes the report. .
Earlier this month, Hubble also revealed the study of the most complete ultraviolet light and the highest resolution of nearby galaxies.
