Re: APOD: Unraveling NGC 3169 (2024 May 23)

This galaxy looks very unique to me. I am a student of galaxies, these look brand new to me. There appear to be ~3 rings around NGC 3169 perpendicular to its plane of rotation. Has the other galaxy circled it that many times? I would love to see the simulation of these 2 galaxies interacting. Note,...

Re: APOD: Unraveling NGC 3169 (2024 May 23)

So, I'm reading that tiny NGC 3165 is also part of this triple, and at about the same distance, yet it doesn't seem to be interacting with the other two at all, either currently or in the past. Why not? Also, I note that NGC 3165 is classified as a spiral too, which would confirm that spirals reall...

[...] According to this site , both NGC 3169 and NGC 3166 have active black holes, and I have to wonder if the jet-like feature emerging from NGC 3166 is a remnant of an outburst of that galaxy's black hole. [...] Ann I think that the "jet" of NGC 3166 is an arm of NGC 3169 that was stret...
