Re: APOD: Solis Lacus: The Eye of Mars (2020 Oct 01)
All I have to say is "what eye?". Is this supposed to be it? If so, I see instead a hand cupping an eight-ball. It even has fingers (or fingernails) on the left side! https://www.youtube.com/watch?v=i1xsOtCpZPQ https://www.nationalgeographic.com/content/dam/news/2016/10/15/mars-maps/04-ma...

Re: APOD: Filaments of the Cygnus Loop (2020 Sep 28)
… So, does anyone have a guess as to where in the full Veil Nebula this close-up filament is? Not that it matters much, but I'm just curious. I suppose knowing the identities of some of the stars might help. The FoV is ~2.5' x 1.2', the location is marked by the white cursor. The narrow filament ju...

Re: APOD: Arp 78: Peculiar Galaxy in Aries (2020 Sep 18)
It is unclear whether any of these galaxies except for NGC 770 are actual companion galaxies to NGC 772, or have any gravitational influence on it. I suppose you’re right, but the coincident trails sure are suggestive. But of course, “coincidence is not necessarily causation”. Actually, I think the...

Re: Wow, that's a BIG Baby!
There is one caveat to that though: One of the few properties a BH can have is charge. So if two BH where both positively or both negatively charged, there would be an electrostatic force of repulsion working against their gravitational attraction.
