HST: A matter of perspective NASA/ESA | 2024 March 4 https://cdn.esahubble.org/archives/images/screen/potw2410a.jpg Here we see NGC 4423, a galaxy that lies about 55 million light-years away in the constellation Virgo.

Re: A Neutron Star Rests at Supernova 1987A’s Center
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: AM1054: Stars Form as Galaxies Collide (2024 Feb 20)
I'd just say that understanding objectively derived probabilities is an important tool for guiding scientific investigation. If you're going to conduct an investigation, it makes sense to start with the most probable hypotheses. Agreed. Thanks. The pair that make up Arp 256 are two of my favorite g...

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...

Re: Discovery of a large and faint nebula at the Triangulum galaxy
I'm not surprised you discovered a new nebula with such a deep and beautiful photo, congratulations! I personally think it is a planetary nebula in our galaxy that shares the line of sight with M33. A weird coincidence, a new PN discovery near NGC 2403 was announced recently . OK. I agree that ther...

Re: APOD: NGC 253: Dusty Island Universe (2024 Feb 15)
... However, I suspect that core outflows from galaxies may happen from time to time, but I also think that they are transient phenomena. Consider the X-ray bubbles of the Milky Way: https://assets.newatlas.com/dims4/default/082ba88/2147483647/strip/true/crop/1400x933+0+0/resize/840x560!/quality/90...

Re: APOD: NGC 253: Dusty Island Universe (2024 Feb 15)
ThanX Ann I would put that into perspective a bit. In the optical wavelengths, perhaps yes. If we compare with other wavelengths like IR, the oval shape suddenly looks anything but oval and the galaxy is suddenly barred too...
