Galaxies Collide Photos

This image shows a pair of interacting galaxies consisting of NGC 5754, the large spiral on the top and NGC 5752, the smaller companion in the bottom left corner of the image. The contrasting reactions of the two galaxies to their interaction are due to their differing masses and sizes. The photos were released to mark the Hubble Space Telescope's 18th launch anniversary.
