Scientists found a galaxy that’s 99.99% dark matter

Astronomers have found a galaxy that is made almost entirely of a mysterious, invisible substance called dark matter. The dark matter galaxy is called Dragonfly 44. It’s roughly the same size as the Milky Way, so you could argue it’s kind of like our evil twin galaxy made of dark matter. Or, as the researchers put it, “Dragonfly 44 can be viewed as a failed Milky Way.” The discovery could help us finally answer 2 big questions about dark matter.
