Lenticular or elliptical galaxy
Constellation: Coma Berenices
Pierre Mechain, was a pretty busy astronomer as I am finding out as we
go through the Messier Catalogue. He discovered this galaxy
in 1781. This galaxy was then added to Messier’s catalogue
as a item not to worry about when comet hunting.
Approx 60 million light-years away, it is also approx 125,000
Astronomers think that approximately 4 to 7 billion years ago, this
galaxy merged with another galaxy which is why its outer structure is
pretty complex with ‘shells & ripples’.
(I’m not really sure what that means.) M85, is also very
poor in neural hydrogen and has a relatively young, if you can call 3
billion years young, stellar population near its centermost region.
This bad boy also has, like most galaxies, a central supermassive black
hole, on the order 100 million, I say million, solar masses!
Pretty cool, huh?
