These “explosions” are produced in a process known as magnetic reconnection, something well studied at Earth and is an important part of Space Weather, involved in energising the radiation belts and producing displays of the Northern lights. Space Physicists led by Lancaster University used data to show that Cassini had passed through the region at Saturn where magnetic reconnection was occurring, which has never before been observed.

One of the mysteries this gives us clues to answering is how Saturn’s magnetic bubble, known as its magnetosphere, gets rid of gas from Saturn’s tiny icy moon Enceladus...
