Re: APOD: Messier 66 Close Up (2021 Jan 28)
If M99 is a cluster breaker distorted by the headwind of the intergalactic media in the Virgo Cluster,
why should M66 be distorted by the other galaxies of Leo triplet? Can M66 be a crusher too?
It has its blue in plenty. Even a Great Blue Pocket.

Re: APOD: Central NGC 1316: After Galaxies Collide (2021 Jan 26)
come to think of it the dust in Cen A can be a disk rather than a tyre and still look like a tyre because of the same visibily trick that make dust streaks in NGC 1316 look so superficial. Then it is no coincedence that the radius of the tyre is the radius of the halo part of the bulge. Our side of ...

trying to imagine a 3d, it's easy to see dusty outskirts as wide tyre around a thin plate wheel. The part near the core is more puzzling. There surely is a large ghostly shine bulge through which we see the far side of the arms' ends. But what are the dusty lanes seen very close to the core due to t...

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...
