For what it's worth, it didn't throw one up for me. Anyway, for anyone wondering what's beyond the slightly clickbaity headline, it isn't about some astronomical phenomenon; the subheading reads "In the past two years, without much notice, solar power has begun to truly transform the world’s energy system." and the article is all about that.
It do not throw up for me either. I was silently hoping that they excluded IPs from more economically behind countries, so we can read. I was happy.
No paywall for me here in the UK. Maybe they consider us an economically behind country too.
