Re: APOD: The Seagull Nebula (2024 Mar 13)
https://apod.nasa.gov/apod/image/2403/Seagull_Lacroce_1080.jpg That's an interesting and very red portrait of the Seagull Nebula. I can't complain. The Seagull Nebula is very red, since it is heavily dominated by 656 nm Hydrogen Alpha, which is of course this color, ███ . Only one other color is im...

ThanX Ann There you made some good points there. It will be exciting to see what future research on this object will reveal as the fog surrounding the central object slowly clears. I think the study above is just a first step and will not be the only one. I like SN 1987A also as WEBBLE ;-) https://...

Re: A Neutron Star Rests at Supernova 1987A’s Center
Thanks for your fantastic images, Jac! I absolutely agree that Sanduleak −69° 202, the supernova progenitor, must have undergone cyclical outbursts. The reason why the outer outlines "from the star to the supernova remnant" are completely unchanged can only mean, the way I understand it, ...

Re: APOD: A View Toward M106 (2024 Feb 22)
Two questions for Ann based on her post above: 1. Don't "jets" from central black holes in galaxies get directed perpendicular to the galactic plane, and if so why would they help to form arms in the galaxy disk? 2. Why do we "have such a good grip on the distance" to M106? Some...
