Story summary

The Small Magellanic Cloud (SMC) is not rotating as expected after a past collision with the Large Magellanic Cloud (LMC).
The finding, published in The Astrophysical Journal, shows the SMC's stars and gas are in disarray.
Researchers used computer simulations to analyze the collision that occurred hundreds of millions of years ago.
The study suggests the SMC's unusual behavior may provide new insights into dark matter and galaxy evolution.
