Starship Asterisk*

some tendril/counter-tendrils 500 ly long can be seen in radio perpendicular to Milky Way plane

But why a galaxy arm should be an axis for a magnetic lines' tube, I wonder

An interesting question is whether or not the spiral galaxy has a sizable black hole of its own. It may have one, but it also may not. Small local spiral galaxy M33 doesn't have a central black hole, at least not one that can be described as "supermassive" in any way. But if the spiral ga...

To me it looks like the jets are like 45 degrees from perpendicular! 1) The jet and the counterjet line can't lie in the plane of the picture because the counterjet seems much paler than the jet and so must be flowing away from us. 2) The dust gas disk galaxy can't lie in the plane of the picture b...

The jet and the lobe are not directed straight at us, however. If they were, we wouldn't see a jet at all, just a very bright central light source. Ann For M87 the angle between our line of site and the axis of the jet and the counterjet: 17±3°. (using apparent component speeds in the jet, 0.21±0.0...

If the foreground galaxy, NGC 3314B, has outer dusty thorus we would not see it.
The hole or brane or disk central part occupies the whole backlight area.
Or may be there is no outer dusty thorus.

And yes, the brown/blue galaxy against backlight/black is amazing here

What I find surprising about that secretive dusty outskirts beside the fact that it's huge and dwarfing the light-emitting part of the galaxy. It's clearly non-planar. So the normal matter (can not call it light matter any more) part is overall not a disk but an R=200 kly thorus with an R=20 kly dis...

" a small foreground galaxy " has a bar, doesn't it?

By the way, ink-black gobule is easy to tell from deep space black when you have an infrared picture to compare.
Ink-black is quite see-through in infrared.

He has just drawn a puzzle for us: what black is background black and what black is foreground black.

"Ghostly red tiles"? It's a region of ionized hydrogen and it has some linear shock fronts around it (which are common enough). That they coincidentally lie at about 90° to each other makes our brains see structure that has no real physical meaning. linear shock front… Like this? https://...

unusual to see spiked stars in another galaxy. They are bright and the LMC galaxy is near.

I wonder what large ghostly red tiles in the background of the top half of the left cavity can be.
They don't feel astronomic at all.

a stellar globular cluster meets just 2 of 3 conditions: 2) a non-colliding particles (stars with no interstellar gas) globe of uniform density to make a harmonic gravity well 3) some billions of years to make a bar with orbital resonance an outer part of galaxy meets just 2 of 3 conditions: 1) a vi...

So the recipe for a bar is:
1) a viscous gas disk to make stars in it
2) a non-colliding dark particles globe of uniform density to make a harmonic gravity well
3) some billions of years to make a bar with orbital resonance

Like a pendulum! A bunch of pendulums with the same fixed pivot, the same length of their massless rods or strings and the same equilibrium position (in the center of the galaxy). Those pendulums (stars, nebulae) can harmonically oscilate on a line through the center, on a circle orbit or on a symme...

But the bar is a stick rotating in galactic disk plane, isn't it?
