Milky Way flipped in collision with dwarf galaxy 10bn years ago, astronomers say
Astronomers suggest the Milky Way may have flipped sideways following a collision with a dwarf galaxy 10 billion years ago.
The brief
The Milky Way may have undergone a dramatic rotation of more than 90 degrees. This event was triggered by a collision with a dwarf galaxy described as sausage-shaped roughly 10 billion years ago.
Coverage from The Guardian, ScienceAlert, and IFLScience emphasizes the scale of the rotation and the nature of the colliding galaxy. The Royal Astronomical Society and Phys.org refer to the event as "cosmic gymnastics." Future focus remains on the mechanisms of this dramatic flip and the impact of the encounter with the sausage-shaped galaxy.
