The shapes of this galaxy and the Hockey Stick Galaxy, seen in the lower left from the Whale Galaxy, are distorted, indicating that the two galaxies are gravitationally interacting. These two galaxies are likely to merge into a larger galaxy. The Subaru Telescope’s Hyper Suprime-Cam (HSC), the ultra-wide field-of-view camera, successfully observed the two galaxies in one shot.
