The galaxy NGC 5775 is a spiral galaxy with a high star formation rate that is in the early stages of a galactic merger with its galactic neighbor NGC 5774, both about 85 million light-years away in the Virgo Cluster.
Astronomers have observed bridges of hydrogen gas at radio wavelenghts connecting this edge-on galaxy with the neighbouring face-on spiral (NGC 5774), see here and here.
There even seems to be a visual connection of the two galaxies visible in this very deep image in inverted mode (below).
The smaller spiral galaxy below is IC1070 situated in a distance of 72 million light-years
