Just looking at them, they appear fairly similar to nebulas within our own galaxy. It took sophisticated spectroscopic measurements to realize they’re actually much further away.

I’m going to leave this here: https://youtu.be/BckqviVaWl0?t=14

If you care to learn orbital mechanics, Kerbal Space Program is a great teacher.

It’s more that 2d projections of 3d objects are wonky and unintuitive.

Many journals are absolute garbage that will accept anything. Keep that in mind the next time someone links a study to prove a point. You have to actually read the thing and judge the methodology to know if their conclusions have any merits.

Scientific papers should be timeless. Can you imagine the hell of having to research the pop culture and slang of an era just to understand a paper written in it?

It’d have to be exceptionally large to clear its orbital path at that distance from the sun. It’ll probably join Pluto in the dwarf planet category.

That’s pretty obviously fake. This is what the real markings look like: https://www.archives.gov/files/isoo/training/marking-booklet-revision.pdf

Documents marked “not for public release” aren’t classified. They’re what’s called controlled unclassified information (CUI). It’s anything from PII, law enforcement victim records to sensitive (but unclassified) technical manuals. There’s dozens of categories if anyone cares to look at them: https://www.archives.gov/cui/registry/category-marking-list

They shouldn’t be sitting out there, but it’s also not a crime.

That comment is so idiotic and/or bad faith that I totally get removing it. Better to remove it than clog up the comments with a dozen people trying to explain why they’re wrong and the OP likely sea lioning them all.
