Rare 'Missing Link' Black Hole Possibly Found in Our Celestial Backyard

Astronomers have detected a possible intermediate-mass black hole in Messier 4, a globular cluster located 6,000 light-years away from Earth. The black hole is estimated to be around 800 times the mass of the Sun, falling into a mass range that is rarely seen. The discovery could help solve the mystery of the dearth of intermediate-mass black holes, which would provide clues about the formation of supermassive black holes. Further observations using space telescopes are needed to confirm the existence of the black hole.
