Robert's Quartet,interacting galaxies. This group of four galaxies is located in the constellation of Phoenix,at a distance of around 160 million light years. NGC 87 (upper right) is an irregular galaxy. NGC 88 (centre) is a spiral galaxy with a diffuse envelope of gas or dust surrounding it. NGC 89 (lower centre) is a spiral galaxy with two large spiral arms. NGC 92 (upper left) is a spiral galaxy that has been distorted by its interaction with the other galaxies. A long streamer of stars,gas and dust (centre left) has been pulled out of this galaxy. The other galaxies in this group also show signs of interactions and increased star formation.
