Video: Dragonyfly 44 - Newly discovered galaxy is 99.99% dark matter

An international team of astronomers has discovered a galaxy made almost entirely of dark matter and roughly the size of our own.

Astronomers overlooked the galaxy due to its dimness and shortage of stars, but are now calling it the Milky Way’s “Dark Twin.”

Meanwhile, the prevalence of dark matter in Dragonfly 44 is leading scientists to question much of our previous understanding of how the universe was created.
