Astronomers led by Song Wang from the Chinese Academy of Sciences, have discovered an unusual celestial phenomenon, potentially the smallest black hole ever detected. The discovery was made approximately 5,

In around a billion years, the cluster is expected to dissolve entirely, leaving behind only black holes orbiting the Milky Way's centre.

Astrophysicists have uncovered a possible swarm of over 100 stellar-mass black holes hidden within a stellar cluster known as Palomar 5.

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end

Astronomers have made a groundbreaking discovery: a swarm of over 100 stellar-mass black holes is traversing through the Milky Way within the star cluster known as Palomar 5. This extraordinary cluster,

Black holes hold some of the universe’s greatest mysteries, with giant empty spots in space sucking in whatever enters their gravitational pull. However, the mystery is now growing as astronomers are now saying there could be a swarm of black holes moving across the Milky Way.
