Strange shapes appearing in the skies over large parts of Queensland on Tuesday sparked a social media frenzy after clouds formed an unusual portal-like hole over Brisbane.
It was not an alien invasion, but actually a fall-streak hole, says Harry Clark from the Bureau of Meteorology, where “Ice crystals start to form and fall down out of the cloud”.
Mr. Clark also said airplanes could also be responsible for the formation, siring up the cloud and allowing the ice to start falling to create the uncommon hole in the sky.
