A glow lasting only 1 hour observed in space in 2019 may have revealed a primordial black hole with a mass of 3 moons, associated with dark matter and considered 100,000 times more likely than common stellar objects by scientists in the study.

Event recorded in 2019 in the Large Magellanic Cloud may have been caused by a primordial black hole: researchers analyzed the gravitational microlens, calculated mass equivalent to three moons, and considered the scenario linked to dark matter more likely, without definitively confirming the nature of the black hole called Phoebe.

A glow lasting only 1 hour observed in space in 2019 may have revealed a primordial black hole with a mass of 3 moons, associated with dark matter and considered 100,000 times more likely than common stellar objects by scientists in the study.. A possible primordial black hole with a mass equivalent to approximately three moons may have caused the brightness increase recorded in a star observed in the direction of the Large Magellanic Cloud. The phenomenon occurred on December 18, 2019, and was identified in data from the Dark Energy Camera, installed on the Víctor M. Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile. According to the Spanish portal Xataka, the invisible object was nicknamed Phoebe and returned to the spotlight in May 2026, after researchers presented an analysis of the episode. The study treats the...
