NGC 4438 contains a very masive black hole that blows huge gas bubbles into space. A closer look at our image shows some parts of the bubble, that is fully resolved only in the Hubble image http://hubblesite.org/newscenter/archive/2000/21/

NGC 4438 may be deformed by its neighbour galaxy NGC 4435 but some other people think that NGC 4438 is already a merged galaxy and NGC 4435 is far behind NGC 4438 and not interacting with NGC 4438.
The image is filled with hundreds of faint background galaxies that belong to a more distant cluster.
