About Galaxies in No Man's Sky
The universe of No Man's Sky is comprised of 256 unique galaxies, which are in turn comprised of many regions, each of which contain several star systems. All star systems feature 1 to 6 planets, and often a number of moons. Imagine a massive pizza box floating in space : that’s the basic shape of a No Man's Sky galaxy
There is 4.29 billion regions (the limit of a 32 bit integer) per galaxy. There are about 18 quintillion (short scale) possibilities for planets (the limit of a 64 bit integer), however not all are currently in use.
18 446 744 073 709 551 616 is 264, it is also equal to 1616
1616 ? Coincidence ? I think not !
Players start in Euclid (1), and travel through galaxies in order by reaching the Galaxy Centre. After the player leaves galaxy Iousongola (255), they return to the first galaxy again.
Odyalutai (256) cannot be reached through normal gameplay, the only ways to reach this galaxy are if you join a player who is already there via Multiplayer, visit a player base on Odyalutai through the Nexus, or using a save editor.
On glyphs.had.sh, we use a fake galaxy call "Maybe Euclid ?" (0) when decoding portal address without specifying a galaxy. It default to Euclid (1).
If we store just 1 KB of data for each region, system, and planet, we'd need around 10 PB (10 000 TB, or 10 000 000 GB) to cover all galaxies. And that's just for minimal metadata!
If we added a 1 MB JPG image for each entry, the total storage would jump to over 34 EB (exabytes). Thankfully, we only save data for discovered locations :)
Hello Games managed to pack it all into just a few gigs, with some truly clever (and admittedly obfuscated) maths ! For the better, right?
