Reply to comment by dickbutt_md in Have you ever thought about what it sounds on jupiter by Western_Home6746

So the metors that plowed into Jupiter years ago just went through? I thought, while small, that in the center there would be a solid something. Not big, because of all the weight and pressure, but something.

No - they didn't "just go through" - they encountered gas that became increasingly denser as one sinks into Jupiter.

There probably is a solid core of rock, but before then you encounter multi-bar pressures, and densities exceeding that of common fluids here.

I wonder if there are layers before the core that have some amounts of solids settled in above higher density gases. So not that it’s a surface but that it’s a layer of solid (even if it’s a dusty consistency) above denser gases

Here are some of the best models we have of Jupiter's near-core:

https://arxiv.org/pdf/1812.07436.pdf

p12 allows for both a sharp discontinuity and a gradual 'fade' from metallic hydrogen to rock. The data we have cannot distinguish between those models.

"The existence of a diluted core, or a steep heavy-element gradient inside Jupiter is actually consistent with formation models of Jupiter (see section 4.3 for details). Giant planet formation models in the core accretion scenario (e.g., Pollack et al., 1996) suggest that once the core mass reaches ∼ 1 − 2M⊕ the accreted solid material (heavy elements) vaporise and remain in the planetary envelope (e.g., Stevenson, 1982). This leads to a structure in which the deep interior is highly enriched with heavy-elements, with no sharp transition between the core and the inner envelope (e.g., Helled & Stevenson, 2017 and references therein)."
