SUMMARY: The European Southern Observatory has released a beautiful high resolution image of Robert's Quartet; a group of 4 very different galaxies located about 160 million light-years from Earth. Its member galaxies are NGC 87, NGC 88, NGC 89 and NGC 92. Robert's Quartet is one of the best examples of a compact group of galaxies, which can contain anywhere from 4 to 8 galaxies, and interact with each other from time to time. One galaxy in the group, NGC 87, has large regions of furious star formation because of its interactions with its neighbours.

The quartet is one of the finest examples of compact groups of galaxies. Because such groups contain four to eight galaxies in a very small region, they are excellent laboratories for the study of galaxy interactions and their effects, in particular on the formation of stars. Indeed. :D
I like the picture, too.:p

Thank you, Fraser - you really do find some interesting stuff!
