Spacecraft Juno to Study Jupiter

Great documentary.
Turns out Jupiter is mostly liquid hydrogen 3000 miles below the surface. So its not really a ball of gas.
Also there is the great blue spot which is a magnetic hot spot not previously detected.
Flux Tubes, powerful rings of radiation leading to Io and other moons
Fantastic documentary - I really enjoyed watching it, and thanks for sharing.
Completely agree; awesome, astonishing, and absolutely gorgeous, beautiful and breathtaking, all at once.

Using its green filter, the spacecraft’s JunoCam visible-light imager captured almost an entire side of the water-ice-encrusted moon. Later, when versions of the same image come down incorporating the camera’s red and blue filters, imaging experts will be able to provide a color portrait of Ganymede. Image resolution is about 0.6 miles (1 kilometer) per pixel.
In addition, Juno’s Stellar Reference Unit, a navigation camera that keeps the spacecraft on course, provided a black-and-white picture of Ganymede’s dark side (the side opposite the Sun) bathed in dim light scattered off Jupiter. Image resolution is between 0.37 to 0.56 miles (600 to 900 meters) per pixel.

“The conditions in which we collected the dark side image of Ganymede were ideal for a low-light camera like our Stellar Reference Unit,” said Heidi Becker, Juno’s radiation monitoring lead at JPL. “So this is a different part of the surface than seen by JunoCam in direct sunlight. It will be fun to see what the two teams can piece together.”
