2: Marine life apparently inhabiting a vacuum.
I'm not really sure where you get this idea from, just because some community members dubbed them space jellyfish has no bearing on their origins, marine or otherwise, just their accidental similarity to other known life forms, you may as well criticise other alien life forms for being "brains on trees" because someone calle them Brain Trees because the growths on the end of the branches ressemble brains or trees in vacuum because we dubbed other Bark Cones. Humans are always going to do that, match new things they see with things they already know, we even do it on earth, that's why we have duck billed platypus, it certainly aint a duck!
But whatever, it's sad to see any players leave the game but personally I think the new exploration mechanic is a big step forward, good luck with wherever you end up, maybe you will be back one day, you never know what the future brings.
