Previous readings from Juno revealed ammonia on the gas giant, which is more than 100 times the size of Earth, was depleted, and experts were unsure what had happened to it.
However, the analysis published in the journal Nature shows that it has been stored in the clouds.
Scott Bolton, Juno’s principal investigator at the Southwest Research Institute in San Antonio, said: “Previously, scientists realised there were small pockets of missing ammonia, but no one realised how deep these pockets went or that they covered most of Jupiter.
“We were struggling to explain the ammonia depletion with ammonia-water rain alone, but the rain couldn’t go deep enough to match the observations.
“I realised a solid, like a hailstone, might go deeper and take up more ammonia.
