## Executive Summary
Astronomers suggest the Milky Way may have flipped sideways following a collision with a dwarf galaxy 10 billion years ago.

## Intelligence 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.

## Verified Facts & Key Claims
### When did the collision occur?
According to The Guardian, the collision happened 10 billion years ago.

### What was the effect on the Milky Way's orientation?
IFLScience reports the collision might have rotated the Milky Way by more than 90 degrees.

### What was the colliding galaxy like?
ScienceAlert and IFLScience describe the colliding dwarf galaxy as "sausage-shaped."
