The clip shows the sun in the blue sky, surrounded by a perfectly round circle.
Onlookers can be heard discussing what was causing the mesmerising sight.
But viewers watching online had some very wild theories.
“It’s a sign,” one commented.
Another wrote: “That looks like a passage into heaven!”
And a third went even further, saying: “A major earthquake approaches.”
But it has since been revealed that the sight – taken in the Chilean capital Santiago – was actually a solar halo.
Halos can have many forms, ranging from coloured or white rings to spots and arcs.
The optical phenomenon is produced by light interacting with ice crystals suspended in the atmosphere.
With crystal clear skies and dry air, Chile is a firm favourite for astronomers and those who love to view the skies and many of the world’s most powerful telescopes are housed there.
It comes just days after an equally bizarre phenomenon filmed over Sweden sparked claims it was a “gateway to heaven”.
And conspiracy theorists feared the apocalypse was coming after the sun mysteriously turned red.
