Scientists reviewing 34 year old data from the Voyager 2 mission found something interesting: a plasmoid.

Plasmoids are clusters of ionized gases from a celestial body's atmosphere. The bursts of material are pushed away from the planet by its magnetic field. This is the first time a plasmoid has ever been recorded from Uranus.

Earth leaks about 90 tons of atmospheric material each year.

This plasmoid measured 127,000 miles by 250,000 miles.
