	The intro seems to major a little too heavily on the habitability aspect. Only four of the items in the comic mention habitability - five if you count the 'Earth-like data artifact' - plus the title text. That's not even a third of the total items. Astronomers aren't only interested by worlds that might be habitable - they're excited by the vast array of interesting things out there.

-::This is my reading of it too: the planet being within the habitable zone of the accretion disk is (IMO) referencing a very young solar system, discovered at some time before the planets have swept their orbits clear. Therefore although "habitable", it'll be a few hundred million years before even what we hypothesize as the "Late Heavy Bombardment", concomitant with the very earliest traces of life on Earth. In other words, great news for future colonization as long as your hopes for the future are not contingent on there being anyone remotely human still being around...

 I'm a little unsure of this so could someone help me confirm my theory? There is a shape in xkcd: Escape Speed that looks quite similar to the "faint dust cloud that will cause several papers to be retracted" shape (in xkcd: Exoplanet System). I'm wondering if xkcd: Exoplanet System might be a map of the xkcd: Escape Speed world? [[User:RedDragon|RedDragon]] ([[User talk:RedDragon|talk]]) 14:53, 17 June 2025 (UTC)RedDragon
