That's one of my favourite hints in Outer Wilds. You will see a Supernova. Not with a fancy telescope, it's visible to the naked eye, and if you watch the sky you'll see another soon enough. You can see this right at the start, and unlike the random direction of the probe launch you don't need any game lore to, if you're smart enough, put two and two together.
It's funny, I noticed I happening and thought it was proof of the opposite - that there had to be some artificial cause for the supernovae (including the Sun), because a real supernova takes many years to progress, not 20 minutes.
Even after visiting the Sun Station I didn't believe it and thought it was a narrative red herring....so the ending was a surprise to me. Somehow.
Honestly one of those rare games that makes you feel like a real explorer, not just someone following a path the devs laid out.
Truly one of the most purest of video games in terms of player freedom, I’m still sad that I didn’t think to record my own playthrough as everyone’s path of discovery is more or less unique.
The freeform gameplay and incredible ending makes OW easily my pick for best game of all time, even though it’s also my least replayed favorite game.
I hope that game will be treated like LothR or Shakespeare, it is truly special experience.
