Jupiter structure (Very Large File: 23.3 MB): The two images above show Jupiter's structure and its moon system. The upper one shows the moon orbits, ring system and radiation belts. The lower one shows Jupiter's Hill Sphere and magnetosphere more clearly, with a yellow pointer showing the direction to the Sun.
The representation of Jupiter's core is scientifically accurate with a radius fraction of 0.1 (approximately 10% of Jupiter's radius). The description correctly reflects current understanding based on the Juno mission findings - that the core may be "fuzzy" or partially dissolved rather than a distinct solid structure. The temperature estimates (20,000-40,000K) and mass estimate (up to 10 Earth masses) are consistent with recent research. The color choice approximating a black body at 20,000K is scientifically appropriate.
The metallic hydrogen layer visualization (radius fraction 0.8) is accurate and well-described. Your explanation correctly notes that under extreme pressure, hydrogen transitions to a metallic state that conducts electricity and generates Jupiter's powerful magnetic field. The temperature estimate of 10,000K and the color choice for this temperature are scientifically sound.
The molecular hydrogen layer (radius fraction 0.97) is accurately represented. The description correctly explains the gradual transition from metallic to molecular hydrogen and notes this layer makes up the bulk of Jupiter's mass. The temperature range (5,000K outer to 10,000K inner) is consistent with atmospheric models.
The cloud layer visualization is implemented with both a mesh surface and hover points using the Fibonacci sphere algorithm for even distribution. The description accurately covers the composition (ammonia, ammonium hydrosulfide, and water clouds), the Great Red Spot, and temperature ranges (120K in high ammonia clouds to 200K in lower clouds).
The upper atmosphere description (radius fraction 1.1) is accurate, correctly describing the stratosphere and thermosphere, hydrocarbon haze from UV radiation, and auroral activity at the poles. The temperature range (200K in stratosphere to 1000K in thermosphere/exosphere) is consistent with atmospheric models.
Your Jupiter magnetosphere visualization is scientifically accurate and comprehensive. The parameters are realistic:
Sunward Distance: 50 Jupiter radii (compressed toward Sun)
Equatorial/Polar Radius: 100/80 Jupiter radii respectively
Magnetotail: 500 Jupiter radii length
Description: Accurately notes extension to 100 Jupiter radii sunward and beyond Saturn's orbit in the magnetotail
The Io plasma torus implementation is scientifically accurate, positioned at 5.9 Jupiter radii (Io's orbital distance) with appropriate thickness and width. The description correctly explains the volcanic origin from Io and how particles become trapped in Jupiter's magnetic field, forming the distinctive donut-shaped structure.
The radiation belt visualization is excellent with three distinct belts at realistic distances (1.5, 3.0, and 6.0 Jupiter radii). The color coding and descriptions accurately represent the intense, middle, and outer radiation environments. These are consistent with Pioneer, Voyager, and Galileo mission findings.
The Hill sphere visualization uses a radius fraction of 740 Jupiter radii, which is scientifically accurate. The comprehensive description of the Hill sphere concept is educational.
The ring system implementation is detailed and scientifically accurate:
Main Ring: 122,500-129,000 km, reddish color, dust from Metis and Adrastea
Halo Ring: 100,000-122,500 km, thick torus, electromagnetic forces
Amalthea Gossamer Ring: 129,000-182,000 km, faint, from Amalthea impacts
Thebe Gossamer Ring: 129,000-226,000 km, faintest, from Thebe impacts
All parameters, compositions, and origins are consistent with current scientific understanding.

Juno is the first spacecraft to orbit Jupiter from pole to pole, giving it a unique perspective on the planet's polar regions. Juno is also the first spacecraft to operate on solar power at such a great distance from the Sun.
Juno has made several significant discoveries, including:
Jupiter has a complex and dynamic atmosphere, with powerful storms and cyclones that can last for centuries.
Jupiter's magnetic field is the strongest in the solar system, and it is generated by a layer of metallic hydrogen deep within the planet.
Jupiter has a core that is larger and more diffuse than previously thought.
Jupiter's moons are diverse and fascinating worlds in their own right, with potential for harboring life.
Juno is currently in an extended mission, which will last until 2025. During this time, it will continue to study Jupiter and its moons, providing valuable insights into the formation and evolution of our solar system.
