more than enveloped in a bubble there appears a distinctly red column, obliquely aimed at the galactic center to the left, ad perhaps from behind also to the right. Is this a anomaly of the imaging or active galactic center ? M82 has messy jets, and the artists conceive columnar jets always orthogon...

If Triangulum galaxy is 3MLY from us and perhaps orbiting Andromeda, then considering MilkyWay galaxy 2MLY from Andromeda galaxy, with this pair colliding in 2BY, what can one say about the motion and longterm prospects of collisions with the Triangulum galaxy? Any links to 3D representations of rel...

The picture may well contain scientifically useful info, but the pareidolia distracts from it, doesn't amuse me & doesn't add to MY scientific knowledge.

I don't find amusement in pareidolia.
More I am reminded that I do not understand the color variation.
Is it temperature of same gasses, differences in gas concentration, dust or other matter inclusions? Accomplished by what mechanisms?

Less than a year ago the Fermi Bubble were big news. I was amazed to see them here prominently, but wholly uncommented, without noting!

forget for fitting the monitor; my horizon in horizontal!

Seeing two galactic nuclei 'close' to one another only speaks to position. The relative speed in passing has just as much to say about the amount of time until coalescence, as they may swing to highly separated yet again.

and what of volcanic IO?

Comparing the 3ly on a side at the center of the cluster to 4ly to the alpha centauri system: place the Sun at cube center with the centauri system at a vertex, a corner, gives the smallest cube with side length computed: 4^2= sqrt(8)^2 + sqrt(8)^2 for half side length 2sqrt(2), side length 4sqrt(2)

I see, without caption comment, a faint disk DOUBLING the radius of the apparent galactic disk. Any ideas on this larger disk?

regarding the The Tidal Tail of NGC 3628 of July 27: who was the galaxy that stretched the tail out? Is it out of the view of this image, or due to a no longer obvious motion of one of the other 2 [m65 m66] galaxies in the triplet?
