Jupiter’s wild storms ‘like nothing we’ve imagined’
NASA spacecraft Juno has delivered images capturing wild storms on Jupiter.
Mission chief scientist Scott Bolton of the Southwest Research Institute in San Antonio says the photographs are significant because they reveal Jupiter’s northern polar region is stormier than expected and appears bluer than the rest of the planet.
“This image is hardly recognisable as Jupiter,” he said in a statement.
NASA on Friday released a batch of close-up pictures taken by the Juno spacecraft last week when it flew within 4000km of Jupiter’s dense cloud tops.
During the rendezvous that took Juno from pole to pole, the solar-powered spacecraft turned on its camera and instruments to collect data.
The first glimpse of Jupiter’s poles came in 1974 when Pioneer 11 flew by on its way to Saturn.
The detailed pictures taken by Juno look “like nothing we have seen or imagined before,” Bolton said.
Juno also sent back unique views of Jupiter’s bright southern lights considered the most powerful in the solar system.
The flyby was the first of three dozen planned close passes during the 20-month mission.
Juno is only the second mission to orbit Jupiter.
When it completes its job in 2018, it will deliberately crash into Jupiter’s atmosphere and disintegrate.
NASA planned the finale so that Juno won’t accidentally smack into Jupiter’s moons, particularly the icy moon Europa, a target of future exploration.
