Galaxy C153

The spiral galaxy rushes with 2000 km/s through the center of the cluster Abell 2125, of which it is its brightest member. There to all appearances the intergalactic matter is very dense, because it snatches away all free gas and dust clouds from the galaxy. Those get trailed in long streams. In maybe 100 million years it will have lost all its gas and its spiral arms.
The snatched gas itself shows a high star forming rate and maybe will form a new galaxy in the clusters' center.
