Juno is taking the next step beyond what Galileo foreshowed us which， is the telescope to look at the outside. And we’ve come up with ways of looking at what’s inside of Jupiter. And from this, we’ll understand how it was built and how it came to be.

 

From what we understand, the planet was formed from the disc of gas and dust swirling around our new-born sun. Matter collided with matter. It was a game of gravitational survival of the fattest, a race that Jupiter ultimately won. Planets, like people, are what they eat. Did Jupiter gobble up most of the abundant light-weight gases first before all the solid stuffs started banging around? Or did it form like all the other planets, but grab more than its fair share of ice and gas from the cosmic chiller? The molecules of Jupiter’s first meals, rocks, ice, vapors or dust are still trapped somewhere inside.

 

When the Galileo probe measured higher levels of rare and heavy gases than anyone was expected, things got more complicated.

 

That did not fit any theory of how the planets were made. And so in one quick scoop of time, all the theories of how the planets were made, including the Earth, were not the window.

 

Juno will continue where Galileo left off, trying to unravel the mystery of Jupiter’s formation.

 

We do this by looking down deep in Jupiter and understanding first whether there is a solid core in the middle of it.
