New Observations By NASA’s Juno Spacecraft Are Shaking Up Theories About Jupiter’s Auroras

Jupiter features the largest and most powerful auroral display in the Solar System. As spectacular as they are, however, very little is known about these dancing displays of Southern and Northern lights. A recent survey by NASA’s Juno spacecraft is providing new evidence about Jupiter’s auroras — and it’s becoming increasingly clear they’re not at all like what we expected.

>>>Jupiter’s auroras are powerful, to say the least. The gas giant’s magnetic field, the totality of which is known as the magnetosphere, is 10 times stronger than Earth’s

The stronger the magnetic field, the larger the magnetosphere. Some 20,000 times stronger than Earth’s magnetic field, Jupiter’s magnetic field creates a magnetosphere so large it begins to avert the solar wind almost 3 million kilometers before it reaches Jupiter. The magnetosphere extends so far past Jupiter it sweeps the solar wind as far as the orbit of Saturn.

10 times stronger vs 20,000 times stringer.
Could the difference be due to Jupiter’s bigger surface area? ie. local field strength vs total field strength?
Will check it out.

Well spotted.
