Although most galaxies fall into well defined classifications, there are some that defy all attempts at classification. While some strange and bizarre galaxies are the result of gravitational interactions with other more massive, and sometimes less massive objects, they all have one thing in common; they look more like artists’ impressions than real, tangible collections of billions of stars.

This NASA/ESA Hubble Space Telescope view shows some important details of NGC 6861. One of the most prominent features is the disc of dark bands circling the centre of the galaxy. These dust lanes are a result of large clouds of dust particles obscuring the light emitted by the stars behind them.
