Story summary

Researchers have found a supermassive black hole in Segue 1, a faint dwarf galaxy near the Milky Way, weighing about 450,000 solar masses.
This finding challenges the idea that Segue 1 and similar dwarfs are dominated by dark matter.
The study, led by Nathaniel Lujan of the University of Texas, indicates that other faint dwarfs could host massive black holes and evolve differently.
