Dark matter has been a mystery for decades. A strange 2019 event could be the evidence we were looking for to unravel it

Astronomers reanalyzed a 2019 one-hour brightening event, Phoebe, in a star in the Large Magellanic Cloud.

The data suggest a tiny object passed in front of the star and acted as a gravitational microlens.

Their odds strongly favor a primordial black hole over a rogue planet, by about 100,000 to 1.

If confirmed, it would be major evidence for primordial black holes as a possible component of dark matter.
