Recommended Posts

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.
