Scientists using the MeerKAT Radio Telescope have discovered a mysterious object in the NGC 1851 globular cluster, 40,000 light-years from Earth.

The object's mass lies between that of neutron stars and black holes; it could potentially be a massive neutron star or a low-mass black hole formed through a merger of two neutron stars.

The object, accompanied by a pulsar, might be a pulsar-black hole binary system.

The object has a mass of 2.5 times that of the sun, which surpasses the upper limit for neutron star mass, suggesting it could be a new type of star or the lightest stellar mass black hole ever found.

Further research is needed to determine the true nature of the object, which could enhance understanding of neutron stars and black holes.

The discovery could offer new opportunities to test Einstein's general relativity and gain insights into the properties of black holes.

Researchers plan to continue observing the pulsar with other telescopes to gather more information.

This discovery has potential to provide valuable insights into gravity, core physics, our understanding of matter and the universe.
