| Quote spacer (  ) all of that radiation coming from jupiter? magnetosphere?
Most of it is due to Io. Release of SO2 by volcanism and sputtering of Io's surface produces a tenuous atmosphere. These particles are eventually dissociated and ionized, at which point they are whipped up by Jupiter's magnetic field until they are rotating with it. This process feeds the Io plasma torus, and is the source of most of the energetic particles around Jupiter.
Wikipedia discusses it pretty well.

| juno closest approach to jupiter will be 5000kilometers. wouldnt it be really dangerous to all of the electronics and solar panels of juno?

No. This is below the altitude of the radiation belts (see image)

| Aside from the radiation hazards which are minimized from the highly elliptical polar orbit, what about collision with micro meteoroids while traversing Jupiter's tenuous but existent ring system?
In this NASA's article it is stated that, at closest approach, Juno will be (was) traveling at a speed of ~200K Km/Hr (about ~ 58 Km/sec). I can only imagine what a collision with a 1 cm object could cause  .
I suspect the orbit is highly elliptical so at closest approach it passes way inside of the inner ring and at apoapsis it passes well outside of the outer ring. But still crossing the orbital plane of Jupiter's rings and moons must be a risk..

| I wish it had a hexagon or some other feature on the North pole. So what would jupiter look like without the red spot?

Well, cloudy? 
Otherwise, I think it would be blueish above clouds.
infrared image of southern aurora for the 1rst time ever.
This is so exciting.. !!!
