The strange phenomenon appeared in Canberra's night sky on January 3, being returned and posted on YouTube.

Besides the mysterious explanations about aliens, there are also explanations based on scientific knowledge.
Red and green light often appears in the sky when there is aurora phenomenon, astronomer Brad Tucker at Australian National University said.

However, aurora occurs only when the solar storm sweeps into the Earth's atmosphere, while the ball of light exists when there are no reports of a solar storm.

In nature there are also some phenomena that emit similar blue light aurora. Scientists say that if a storm carrying thunder interacting with some of the above gases can produce green or red light.
