Dark matter is putting the brakes on our Milky Way galaxy’s spin

3 min read



The Milky Way rotates at a whopping 130 miles (210 kilometers) per second, but a new study has found that dark matter has slowed the rotation of its bar by at least 24% since its formation nearly 14 billion years ago. 

“Astrophysicists have long suspected that the spinning bar at the center of our galaxy is slowing down, but we have found the first evidence of this happening,” study co-author Ralph Schoenrich, an astrophysicist at University College London, said in a statement.
