Weird crater[edit]

"Weird" bright crater on Ceres.
Oxo crater - context
"Hexagonal-ish" craters on Ceres.

Does anyone have an idea what's going on at the weird bright crater in this image? It looks like it consists of two parts, one of which is distinctly non-round. --JorisvS (talk) 10:06, 3 October 2015 (UTC)

Could it be the "pyramid" mountain? BatteryIncluded (talk) 21:58, 3 October 2015 (UTC)
That image isn't Pyramid-shaped mountain on Ceres. But it is one of the other "bright spots" on Ceres, the ones in Occator crater weren't the only ones. That image suggests to me a sinkhole, which I also notice on Occator's surroundings. I suspect that in both cases an impact created an underground slurry which flowed and then sublimated, undermining the surface. The current bright area in this image could be ice that was exposed by a landslide. I also rather suspect several Ph.D. dissertations are going to be written on the topic, and our guesses here won't answer the question :-). Tarl.Neustaedter (talk) 22:19, 3 October 2015 (UTC)
I was thinking something along those lines as well. I hope we don't have to wait too long for an answer. --JorisvS (talk) 22:25, 3 October 2015 (UTC)
Look at these hexagonal-ish craters (see image above). Start with something like that, then have another crash on top of it, and you might get something like what you see. Tbayboy (talk) 11:59, 6 October 2015 (UTC)
Hmm, funny craters. I also get the impression that the weird crater is on top of a mountain. Or is that just my imagination due to the bright streaks? --JorisvS (talk) 14:03, 6 October 2015 (UTC)
I've identified the crater as an unnamed crater near Ceres's prime meridian, at about 45 degrees north. it either IS or is near Oxo crater. The whole area is low in elevation, and to the resolution of Ceres's topographic map, there is no mountain in the area. Considering the sharpness of the slope, I would say that the crater itself is astronomically young, and the shape mentioned is a collapsed subterranean cave system. exoplanetaryscience (talk) 15:36, 31 October 2015 (UTC)

Checked. Archive use looks good. Tarl.Neustaedter (talk) 05:53, 16 November 2015 (UTC)

Gallery contents[edit]

This is not my area of editing involvement but, somehow the page made it to my watch list. My concern is are we going to list (by link, not display) every image of Ceres that exist ? Seems a better way to do this is to link to Photos of Ceres by Dawn category on Commons. Mlpearc (open channel) 18:41, 4 January 2016 (UTC)

@Mlpearc: Thank you for your comments - and suggestion - yes - agreed - this could be an option of course - the present method of linking to images seems convenient for me (and perhaps others?) to track/sort the very latest images as they become available - however - I'm flexible with this - iac - Thanks again for your comments and all - and - Enjoy! :) Drbogdan (talk) 19:07, 4 January 2016 (UTC)
Yes check.svg Done => Brief followup - as an additional alternative, added a "Photos of Ceres by Dawn on Commons" link to the Gallery/"Mapping orbits" table title in the main article - Enjoy! :) Drbogdan (talk) 17:35, 6 January 2016 (UTC)
I value the work DrBogdan does in all his articles, so it is difficult to me to express agreement with Mlpearc. The list of links to images (about 166) in the Gallery section is unlike anything I have seen in Wikipedia. Cheers, BatteryIncluded (talk) 19:38, 4 January 2016 (UTC)
