    The cosmos fascinates us with its mysteries, and astronomers have just discovered an extraordinary object that remains a puzzle to scientists. Is it a black hole? A neutron star? Or something completely new and unusual?

    This remarkable object is part of a binary system located in the star cluster NGC 1851. It consists of a millisecond pulsar, which spins at a high speed, and a second object with immense mass. It is this second object that is causing confusion among astronomers, as it could have properties of both a neutron star and a black hole.

    Neutron stars are some of the densest objects in the universe. Their density is so enormous that they can collapse in on themselves, forming black holes. To better understand these astrophysical objects, astronomers search for those that are on the boundary between a star and a hole. The observation from NGC 1851 may provide answers to these questions.

    This object is very dark and invisible in most light spectrums, but the millisecond pulsar accompanying it serves as a useful source of information for scientists. Its regular pulses allow for the study of the gravitational field that affects its signal.

    The examination of the mass of both objects in the system has revealed that the unknown object may have a mass between 2.09 and 2.71 times that of the Sun. This classifies it as a “mass-gap black hole,” which falls between the heaviest known neutron stars and the lightest black holes. However, the exact nature of the objects in this astrophysical gap is still unknown.

    If this is the result of a stellar collision, it could be a very light black hole. This would mean that it can freely move within the star cluster, interacting with other objects through its mass and disrupting their systems. Further research will be needed to uncover the true nature of this mysterious object and to potentially discover new astrophysical objects between neutron stars and black holes. Astrophysicists are excited about the opportunity to explore the extreme conditions prevailing in our universe.

    The ongoing discoveries in space show us how much more there is to understand about this extraordinary world beyond Earth.
