Using the newly released data from a new, powerful space telescope, University of Michigan astronomers have discovered that the southeast region, or "Wing," of the Small Magellanic Cloud is moving away from the main body of that dwarf galaxy, providing the first unambiguous evidence that the Small and Large Magellanic Clouds recently collided.

"This is really one of our exciting results," said U-M professor of astronomy Sally Oey, lead author of the study. "You can actually see that the Wing is its own separate region that's moving away from the rest of the SMC."
