Astronomy & Astrophysics is publishing a new statistical study of the so-called 'ultra-compact dwarf galaxies' (UCDs), which are still mysterious objects. A team of astronomers has investigated how many of these UCDs exist in nearby galaxy clusters and groups. They show that the properties of UCDs match those of bright star clusters.
