What I find interesting about this is that this transition also happened in highly unrelated languages such as Hungarian, Greek and Swedish, not only in related Portuguese and French.
- In Hungarian, /ʎ/ in most dialects turned into /j/, but the spelling ⟨ly⟩ was preserved, hence lyuk [juk].
- In Swedish, /lj/ turned into /j/ in word-initial positions, but the spelling ⟨lj⟩ was preserved, hence ljus [ˈjʉːs].
- In Cypriot Greek, /lj/ is often pronounced as [ʝː], especially by younger speakers. In Standard Modern Greek, it always surfaces as [ʎ].
I guess people find it hard to pronounce /ʎ/ but are too inert to change the spelling.
The radius of the currently observable universe is about 50 billion light-years and this map depicts a sphere with a radius of about 1 billion light-years, so if my calculamalations are correct, following through with sphere volume V being V=4/3πr³ this map depicts about 0.001 percent of the observable universe.
At least the vegetation seems to have bounced back in the last 10 years.

You're right, it's very far north, next to the border with Sweden.
Antineutrinos don't interact with almost anything. They're just a bunch of wimps. They're harmless. Neat for mapping nuclear reactors tho.
