Isolated NIRCam and MIRI views of NGC 4449, followed by a composite view with both instrument's data.
Though the small galaxy was ripped apart by the larger NGC 4449, it hasn't been going quietly. Gravitational tidal forces resulting from it being so close to NGC 4449 have created turbulence in the molecular gas across NGC 4449, causing large pockets to gravitationally collapse and form numerous young star clusters.
MIRI's image captures the dusty skeleton of NGC 4449, which traces the bar but also appears more densely concentrated around that bar than the material visible to NIRCam.
