I also found that Canis Major Dwarf Galaxy is the closest galaxy. . . actually being part of the Milky Way itself, and actually being closer to us than the galactic center :/ I suppose maybe our own galaxy has not devoured it sufficiently to distinguish it as just part of the Milky Way, seems odd to me to have a galaxy within a galaxy which is still distinguishable ..

Well I guess it depends on whether you count Omega Centauri as a dwarf galaxy as well! ;-)

Of course now Omega Cen is “just” the largest, most massive and most luminous of our Milky Way’s globular clusters but it was quite probably the core of it’s own Galaxy once and is located 15,800 light-years versus the Canis Major Dwarfs 25,000 ly distance. (Click on my name for source – wikipedia.)

BTW. Like IC342, most of the Maffei galaxy group including its two main galaxies are obscured by the dust and visually mostly hidden by our own Galaxy too.

That got me questioning once again. . . what is the real Universe and not just my perception of it. More clues usually just add to more mystery, what an infinitely perplexing dilemma this whole Universe thing has turned out to be just glad to be lucky enough to be able to contemplate it.

Yes, indeed. the great philosophical – ontological and epistemological – questions combined in one – what is reality and how do I know that?!

It looks to me as if IC 342 flew past/ had and encounter with some other galaxy is a short period of time since the arms on the left of the pic look fairly balanced and the arms on the right look all distorted and pulled apart. Its facinating. Looking at the new Spitzer pic and the distrabution of the gas/dust arms.

Andromeda is the closest spiral galaxy, but I found some other interesting news from an old Universe Today post. Like, for starters the Local Group is considered to be those galaxies within about 4 million light years. So IC342 I suppose would not be considered part of the local group? Which it is not. It is part of the Maffei 1 Group. I am guessing like everything with mass that somehow IC342 or the Maffei 1 Group is still influenced perhaps by our own Local Group? I crack myself up. I am just dieing to know whats going to happen 100 million years from now :) suppose reincarnation is my best hope for that one. http://messier.seds.org/xtra/ngc/maffei1g.html I also found that Canis Major Dwarf Galaxy is the closest galaxy. . . actually being part of the Milky Way itself, and actually being closer to us than the galactic center :/ I suppose maybe our own galaxy has not devoured it sufficiently to distinguish it as just part of the Milky Way, seems odd to me to have a galaxy within a galaxy which is still distinguishable but I suppose it does take a great amount of time for these colossal collisions to completely connect and become indistinguishable from one another, but the closest galaxy is . . . In our own galaxy. Makes me question whether I am capable of rationalizing astronomical (ooh that might just be an oxymoron) distances. So if Canis Major Dwarf consists of about 1 billion stars and the Milky Way consists of about 200 billion or so, that means there is a lot of space for Canis Major to accompany. That got me questioning once again. . . what is the real Universe and not just my perception of it. More clues usually just add to more mystery, what an infinitely perplexing dilemma this whole Universe thing has turned out to be :) just glad to be lucky enough to be able to contemplate it.
