Citizens of the city of Victoria, Australia, where shocked when a mysterious hole in the sky appeared on brought daylight. The unusual event surprised, sacred and even terrified some who thought it would be an alien spaceship. The strange phenomenon immediately went viral, and some blamed global warming.
Nevertheless, this is not the first time an event like this is recorded in Australia. It is a weather phenomenon known as Skypunck or Fallstreak hole. This is produced when the clouds´ water temperature is below zero but still do not freeze. As a result, a large circular or elliptical area appears. This change in temperature can be enough to make water drops freeze and fall off the clouds, leaving behind this distinctive pattern. When the ice crystals are formed, the surrounding water evaporates healing a hole behind.
In November 2014, a similar phenomenon was also recorded; just that it had colorful splashes in it. Many used the popular social network Reddit to publish images of the strange event, having it become almost immediately viral worldwide. Thousands of people let their imagination run wild trying to explain this beautiful natural phenomenon.
For some reason, this phenomenon was related to UFOs, having many suggest that aliens were involved. Nevertheless, it is all due to the Bergeron process, which is when water cooled to a freezing point, simply drops from the sky.
The Bergeron´s theory is the most plausible to explain this weather phenomenon. According to Wikipedia, “The rationale is that the relative humidity is higher than a surface of ice over a water surface. This means that every cloud top is below zero degrees”. Allowing to this theory, some scientist have tried reproducing this natural phenomenon to validate the theory and have actually succeeded.
This natural phenomenon, like many others, is proof of the wonders and beauty nature.
