Re: APOD: Mystic Mountain Monster being Destroyed (2020 May 25)
In the lower right there is a rather interesting warped dust cloud. Is there more to be said about this object?

There are quite a few stars that appear to be surrounded by something red. Is this an illusion created by the optics or something real?

Re: APOD: Southern Moonscape (2020 Feb 06)
Perhaps a naive question but how did the centers of the oldest craters become flat? Tycho seems bowl shaped with a central peak but most of the larger ones don't appear to be like that.

I too think it's an amazing picture and well composed with the ship!
But I must admit, at the risk of some ridicule (at my age of 76), what comes to my mind is it's a giant Sun bra.

Re: APOD: Galileo's Europa Remastered (2019 Nov 29)
I curious if there is speculation about what constitutes the rust colored material filling the cracks. I would presume it is from the interior ocean but perhaps its a reaction between the rising 'slush' and solar radiation.

Re: APOD: Simeis 147: Supernova Remnant (2019 Nov 21)
Is there any way to estimate the mass of the original star relative to our Sun? I'm just musing about whether our star might produce something that beautiful sometime in the future.

Re: APOD: Spiral Galaxies Spinning Super-Fast (2019 Nov 05)
Is it possible to estimate a maximum angular velocity within these galaxies? Stating that "UGC 12591 spins at about 480 km/sec" doesn't give me a sense of how fast it is spinning.

Re: APOD: Molecular Clouds in the Carina Nebula (2019 Oct 02)
Yes - that is why I suggested exactly that in my post. However, there are at least 10 "clouds" with glowing edges in that image. It would seem unlikely that each has a bright star directly behind it from our vantage point.

Re: APOD: Molecular Clouds in the Carina Nebula (2019 Oct 02)
Thanks for that explanation but it begs the question (in my mind) -- why is the illumination just at the edges from our perspective? If the recombination with the ionized boundary layer causes the glow, why doesn't the entire "cloud" appear to glow? Simplistically, it appears that a very b...

Re: APOD: Messier 61 Close Up (2019 Aug 28)
Beautiful image!
FWIW I noted a very cute little (apparently) barred spiral galaxy near the right edge. Presumably much farther away than M61.

Re: APOD: Rumors of a Dark Universe (2019 Aug 04)
Perhaps I'm missing something but I wonder whether the statement "a supernova that occurred in 1994" might more properly be "a supernova that was observed in 1994." Apparently it "occurred" some 50 million years ago.

Perhaps a naive question: is that yellowish object at the visual center of the Ghost the star that is dying or merely a fortuitous foreground object?

Re: APOD: First Horizon-Scale Image of a Black... (2019 Apr 11)
The issue of "ball" versus "disk" is still somewhat a puzzle to me. On the one hand, we're used to things like planetary motion being more or less like a disk around the gravitational center. But galaxies aren't flat so matter would be falling towards a BH from all directions. If...

Re: APOD: Twin Galaxies in Virgo (2019 Feb 01)
There's an interesting object just to the right (2 o'clock) of NGC 4567. Looks like a very small spiral galaxy. Of course it might be very far in front or behind the Butterfly.
FWIW:
