A grazing encounter between two spiral galaxies, 1999.

This image of two galaxies was taken by the Hubble Space Telescope HST NGC 2207 Milky Way wide field planetary camera WFPC during deep space studies undertaken by Hubble. To the left of the image is the larger galaxy, catalogued by NASA as NGC 2207, the smaller galaxy is IC 2163. Strong tidal forces from NGC 2207 have distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light-years toward the right-hand edge of the image. In addition to the Hubble images, measurements made with the National Science Foundation's very large array radio telescope in New Mexico reveal the motions of the galaxies and aid the reconstruction of the collison.
