NGC 6397 : Concentration of small black holes discovered
Globular clusters are extremely dense stellar systems, which host stars that are closely packed together

Washington: In an unexpected finding, astronomers have discovered a concentration of smaller black holes, instead of one massive black hole, lurking at the heart of the globular cluster NGC 6397.
Globular clusters are extremely dense stellar systems, which host stars that are closely packed together.
These systems are also typically very old the globular cluster at the focus of this study, NGC 6397, is almost as old as the universe itself.
This cluster resides 7,800 light-years away, making it one of the closest globular clusters to Earth. Due to its very dense nucleus, it is known as a core-collapsed cluster.

A team of astronomers was surprised to come across a cluster of small black holes lurking in the universe 7,800 light-years away.
The Hubble Space Telescope uncovered the mass at the heart of globular cluster NGC 6397, according to NASA.
The cluster is said to be almost as old as the universe. Also known as a core-collapsed cluster because of its dense stellar system, researchers thought the grouping was a massive black hole at first.
