Comet smash behind mysterious water on Jupiter
The mysterious traces of water in the upper atmosphere of Jupiter came from a comet that smashed into the largest planet of the solar system in 1994, the European Space agency (ESA) has found.
ESA’s Herschel space observatory solved the long-standing mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994.
