Re: APOD: Animation: Black Hole Destroys Star (2024 Jun 16)
It's quite rare, but it would be fun to see a simulation of a star falling straight into a black hole, a direct hit as it were. It probably makes more sense to visualize that scenario the other way around... a black hole falling straight into the star. And why is that? When I think of this event I ...

Re: APOD: Prominences and Filaments on the Sun... (2024 Jun 15)
I suppose this is pointing out the obvious, but although all the prominences we see in this image are on or very near the planar edge of the Sun we happen to be seeing here, the entire surface of the Sun must in fact be studded with prominences, much like looped carpet piling on a shag rug.

Re: APOD: SH2-308: The Dolphin Head Nebula (2024 Jun 07)
I'm on very shaky ground here, but I think Johnny is right. I think rotation may indeed have something to do with how fast a star exhausts in core hydrogen and turns into a red giant. I think that a sufficiently fast rotation may mix the interior gases of a hot star in such a way that more hydrogen...

It's interesting/amusing that the image at one of the W-R links shows another dolphin-like nebula, this time depicting the entire body: https://earthsky.org/upl/2022/07/Wolf-Rayet-star-WR-134-June-2020-scaled-e1659119484487.jpg Perhaps dolphins like to play near the strong winds of Wolf-Rayet stars! 😊
