NASA has released photographs and audio of a powerful lightning storm on the planet Saturn that is eight times the surface area of Earth.
The storm is so long it encircles the giant planet and its head can be seen overlapping with its tail.
Images captured by the NASA Cassini spacecraft show a storm that is about 500 times larger than the biggest storm previously seen on Saturn.
Lightning released by the storm is emitting radio waves about 10,000 times stronger than lightning bursts on Earth and occur more than ten times per second, according to an article on the storm published in the journal Nature.
The sound of the lightning strikes can be heard here.
Storms this size only occur on Saturn about once every 30 years.
