A massive clump of dark matter may lurk in the Milky Way

Scientists detected a massive dark matter clump near our solar system by studying pulse patterns of dead stars called pulsars. The invisible blob, located 3,260 light-years away, has a mass roughly 10 million times greater than the sun and was discovered when researchers noticed gravitational effects on pulsar signals that couldn't be explained by visible matter. This represents one of the first direct detections of a dark matter subhalo and could help scientists better understand the mysterious substance that makes up most of the universe's matter.
