However, as Daily Mail reports, the mystery of the hole in the sky was quickly cleared up by meteorologists. They explained that the phenomenon, known as a fallstreak hole, occurs when the water temperature in the clouds is below freezing, but the water, in a supercooled state, has not frozen yet due to the lack of ice nucleation.
Fallstreak formations are super rare and can expand up to 50km, which is why they are often mistaken for UFOs.
