Weird cloud appears over Australia, scientists not baffled

Is it a bird? Is it a plane? Nope, it's a fallstreak hole.

Is it a sign of the impending apocalypse? Is it a portal to another universe? Is it an anomaly in the space-time continuum? Is this what the ancient Egyptians warned us about?

Um, no. At least according to Australian meteorologists, who say that this rare cloud formation spotted in the country is a perfectly naturaly, if seldom-occurring phenomenon.
