“Part of the reason for that shape is that these galaxies are still so close to each other, and NGC 2444 is still holding on to the other galaxy gravitationally,” participating astronomer Julianne Dalcanton, of the Flatiron Institute’s Center for Computational Astrophysics in New York and the University of Washington in Seattle, said in the Hubble statement.
