In respiration we oxidize substances, but if it there was a way of respiration that uses reduction, so CO2 could be used as a fuel, even if the organism lives in an oxidized environment? With this we could have a planet that most of it's atmosphere is CO2, so the organisms will have plenty of fuel ...

I dont know if a premature release will be good. all this waiting actually is producing something that is worth it.

I don't know. I love what the previews show. Even if certain terrain updates aren't fully implemented, 9.9.0 will be great.

I've found a couple cool low pressure high oxygen worlds, RS 8474-253-8-15053162-512 3, RSC 8474-1192-4-2250-24 3, RS 8474-1792-8-9448635-211 4, and HIP 11337 5.4. Although I am using a couple visual mods, a bunch of ship mods, and a couple planet addition mod, but I don't think those would change ...

I suspect it's some sort of anomalous tidal heating. That's still a little buggy in this version as I understand. I had a similar problem when I tried to make a ternary planet-moon system.

Apparently Cassini got pictures of ringshine on Saturn not long before the end of its mission.

The number one thing I'm looking forward to is ringshine. When that is implemented, will rings also be included in calculating the apparent magnitude of a planet?

I know that every galaxy in SE has a supermassive black hole at its center. So far the most massive black holes I've found are about 5*10 8 solar masses. I know that some central black holes in the real universe can exceed 10 9 and even 10 10 solar masses, but I have not found any. Do such massive b...

I figured it might not have to do with SE specifically. It's interesting since the catalog rings are in png format. IIRC the ring texture files I made are edited copies of Chariklo's ring file.

I found an odd bug a while ago when I created ring textures for some of the planets I made: the gaps in the rings were not displaying properly when lit from behind. Even when tried to make doubly sure that that part of the texture was transparent, it would not appear properly. I had originally made ...

Another thing I'd like to see is the ability to export ring textures. I know you can export the general parameters such as radii and brightness, but it doesn't capture the color or distribution of gaps. I know you can create your own files (I simply copied and edited Saturn's rings from the catalog)...

Since the upcoming version of Space Engine will feature lakes and seas of liquids other than water, it brings to mind the sorts of precipitation these planets and moons would have. One question it raises for me is what snowflakes of carbon dioxide, methane, or some other volatile look like? Snowflak...

One thought I had for the bounds of the temperature categories with 647 K (the critical temperature for water) as the lower bound for hot planets and 1300 K as the lower bound for torrid, as it is a reasonable value for the solidus of basaltic rock.

I think it's a work in progress, which SE is in general. Back when I started with 0.972 some dwarf moons were hot enough to glow like stars.
