This is an image of two spiral galaxies (NGC 4569 and IC 3583) in the Virgo cluster of galaxies, located in the constellation with the same name.
In red it is possible to see an impressive tail of gas extending far away from the galactic disc. This feature is the effect of the interaction with the actual hot gas inside the Virgo cluster.
The image highlights the importance of the environment to understand how galaxies evolve.
