TAIPEI (Taiwan News) – A clip shared on Twitter capturing the stunning view of a “full circle” rainbow last December has received more than 9 million views and been retweeted over 300,000 times.

Keat Grant, a 21-year-old Twitter user from California, posted the footage on Dec. 19 last year, asking “Have you ever seen a full rainbow before?” The location where the rainbow was spotted was not revealed, but the man apparently was standing on a balcony high above the ground when he filmed the footage.

The natural wonder was made even more breathtaking against the backdrop of a clear sky and above an aquamarine bay. “It’s definitely a portal to another universe,” he concluded.

The post has been flooded with comments expressing awe at the unusual sight. Alluding to the folklore that a pot of gold can be found at the end of a rainbow, a Twitter user quipped that since “it’s a circle technically there is no end, so we got bamboozled.”

In fact, rainbows can be circular, but people normally see an arc-shaped rainbow from the ground. It takes rare conditions for the sunlight and raindrops together to form a circle rainbow, and even when conditions are right, the bottom part of such rainbows are often blocked by the horizon. Mountain climbers and pilots are usually the ones lucky enough to see such a wonder, according to EarthSky.
