On December 18, 2019, a star in the Large Magellanic Cloud exhibited a brief increase in brightness, leading astronomers to identify the object responsible as Phoebe. This event, known as gravitational microlensing, occurs when a massive object bends light from a distant star, creating a distinctive brightening pattern. A team from Swinburne University in Melbourne analyzed the data and proposed three possible identities for Phoebe: a rogue planet, a planet from the Large Magellanic Cloud, or a primordial black hole formed shortly after the Big Bang. Calculations suggest Phoebe has a mass about three times that of the Moon, making it too small to be a stellar remnant black hole. Notably, the analysis indicates that Phoebe is far more likely to be a dark matter object than anything associated with normal stars, with a probability factor of 100,000. If confirmed, Phoebe could represent one of the oldest objects detected, having existed for approximately 13 billion years since the universe's infancy.
