Rediscovery by the Real M'koi

Scout ship "The Real M'Koi" Redicovers a legendary world long thought to be lost to the vagaries of stellar drift. The ship was inspired by this artwork from John Wallin Liberto https://www.deviantart.com/captflushgarden/art/Awacs-Koi-584227132 Originally the piece in question was here on ArtStation, but has since been removed. Fortunately, there is still a copy at DA. Thank you , John, for posting wonderful and inspirational art!
Can anyone recognise the world in question? Hint; Backgrounds like that will only be visible deep in the core.
