What's happening with this galaxy


This looks pretty cool, but what is actually happening here?

This looks like the result of a galactic merger, where two galaxies have come together to form one larger galaxy. As the two galaxies sweep through each other on the way to final merger, tidal forces deflect some of the stars outwards into long streams and wisps that can extend many times the diameter of the final galaxy out into space. Continue viewing and you will find many more of these, and some are quite spectacular.

Thanks for letting me know, hopefully I can find some more of those more spectacular ones.
