Re: APOD: M100: A Grand Design Spiral Galaxy (2024 May 02)
Am I correct in thinking that M100 is not a "barred" galaxy? And if so, do we understand why some galaxies are barred and others are not?

Any educated speculation about the cause of the rusty coloration of the long, curving fractures?

Re: APOD: Millions of Stars in Omega Centauri (2024 Mar 28)
Is gravitational attraction causing the stars to move toward the center of the cluster? If not, why not?

Looks more rectangular to me, with the longer axis vertical in the image. But then what do I know?

Re: APOD: Jupiter by Moonlight (2023 Nov 03)
Is Jupiter the tiny little dot in the lower left corner of this image? If so, there is no way I'll ever be seeing any of its moons. Sorry, but the effect of this image is disappointing and underwhelming.

Re: APOD: Introducing Comet Nishimura (2023 Aug 21)
Question: Is anyone else surprised that comets are still being discovered by individual astronomers such as in this case? It seems that automated searches are still not fool-proof. https://www.nasa.gov/nasa-soho-comet-search .

Re: APOD: Shells and Arcs around Star CW Leonis (2023 Jul 17)
I'm surprised no mention was made of the seemingly hexagonal shape of some portions of this image, which are reminiscent of Saturn's polar hexagon. See https://en.wikipedia.org/wiki/Saturn%27s_hexagon . Nature seems to like hexagons.

Yes, to all those puzzled by the color business, me too. Among the most interesting features is the "tail," which looks white in the image I'm viewing.

Re: APOD: Find the New Moon (2022 Jul 25)
Start from the black buoy in the water, go straight up halfway to the height of the sky that you can see in this image. And go a little to the right. There is is, the new Moon. Beautiful image! Ann Yes, it is, and thank you for your help; I'd not have found it without your directions. That said, th...

Re: APOD: A Large Tsunami Shock Wave on the Sun (2022 May 22)
This is my question, too. I get a brief, gif-like animation when I first pull up the APOD website, but then there's no way to see it repeated. (No "play" icon).

Chris Peterson, thank you for this excellent reply/clarification! Makes sense! Might have been good to have added a word about this to the original APOD discussion, but glad to have it now.

". . . this comet will likely not return to the inner Solar System." And the reason for this is . . . ? Would be nice to answer this obvious question! Why/how is this comet different from other comets that do return to the inner Solar System?

Re: APOD: Jupiter's Swmimming Storm (2020 Sep 10)
Has anyone calculated the "ground speed" at which the storm is traversing the planet? Appears that it would be quite fast, relative to the typical ground speed of hurricanes on earth, for example. Fascinating!
