What has Juno discovered since it arrived at Jupiter three years ago?

It has now been three years since Juno arrived at Jupiter .

It has recently completed its 21st polar orbit out of a total of 35 planned orbits.

There was some skepticism about whether Juno would last this long due to the intense radiation around the planet.

But thankfully, Juno quickly discovered that the radiation where it orbits was a lot weaker than initially expected.

This means that even the camera is still operational.

Jupiter has the brightest Aurora in the solar system, with a radiant power of 100 terawatts .

Like Earth , Aurora appear as bands around the North and South poles, but unlike Earth , these Aurora are mainly visible in the ultraviolet.

At the north, the Aurora is much more dispersed, looking more like filaments and flares, whereas at the South Pole the Aurora seems to be more structured and round.

At this time, it is believed these alternating currents are produced because of the turbulence in the magnetic field.

Juno has had the opportunity to orbit directly over the Great Red Spot , where it discovered something very interesting.
