In this image, M65 is top right; M66 bottom right, and NGC 3628 to the left. North is left. Each of the three galaxies is a spiral, however their disks are tilted at different angles from our perspective. M66 and NGC3628 at one time underwent gravitational warping (likely due to M65 passing through).
