Johann G. Koehler discovered this galaxy in 1779 along with its
neighbor M59 while he was trying to hunt down a comet in the same
area. Our guy Messier listed them both in his catalog
shortly after their discovery.
Initially, astronomers felt that there were gravitational interactions
because both 59 & 60 were so close together, the only problem was
that there appeared to be no interactions. Thoughts were that
they only appeared to be close as viewed from earth. This
was the belief until the Hubble Space Telescope showed there were some
indications of tidal interactions and maybe it has just begun.
You will see M60 in our M59, I guess we could have just said that but,
what the heck. A separate image talking just about the two seems to be
15 images stacked
