The violent encounter would have stripped away most of the dwarf galaxy's stars, but it also could have compressed the gas around its central black hole, triggering a new wave of star formation.

That suggests a wave of star formation that travelled down the arms, set off by the collision with IC 4970, with the newest stellar neighbourhoods pushing the galaxy into the top spot in terms of size.

What is more interesting is this final fifth wave is showing a pattern that looks like a wedge-like formation, commonly known in Elliott Wave circles as a diagonal triangle.
