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://...

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, ...

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...

A Neutron Star Rests at Supernova 1987A’s Center https://www.discovermagazine.com/the-sciences/a-neutron-star-rests-at-supernova-1987as-center The James Webb Space Telescope (JWST) first imaged Supernova 1987A (SN) in September 2022.

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...
