A team of Australian scientists believe they have uncovered the cause of one of nature's most bizarre phenomenon - ball lightning.

Ball lightning is typically the size of a grapefruit and lasts up to 20 seconds.
"Ball lightning has been reported by hundreds of people, for hundreds of years and it has been a mystery," said CSIRO scientist John Lowke, lead author of a new study published in the Journal of Geophysical Research Atmospheres.
