Twitter user @pmxpvrtmx posted images of an astonishing spherical cloud over the city of Fujisawa, south of Tokyo.
"When I saw the cloud it was an even more spherical shape, so I regret not taking the photo more quickly," she told Rocket News 24.
While it's certainly an amazing photo, the roundness may be an illusion. An individual in Fujisawa posted a photo reportedly of the same cloud from a different angle.
"While I can’t verify the origin of this image (just above), or whether it was even of the same cloud, it appears that the cloud only appeared spherical from one direction," University in Melbourne atmospheric scientist Todd Lane told ScienceAlert. "That is, the photographer was lucky to be in the right place to capture an interesting image of what is likely an uninteresting cloud. It looks to me to be some form of cumulus fractus cloud."
