Cross-disciplinary, indeed. There’s an asteroid article in Journal of Geophysical Research: Planets vol. 130, #8:
Courville, S. W. Sanderson, H. R. Bierson, C. J. et al. Ferromagmatic Intrusions on Asteroid (16) Psyche May Be Magnetized 2025JE009031
Volcanoes are volcanic, right? Well, not if our notion of “volcano” is tainted by our Earthly experience. Earth is a terrestrial planet, with lava volcanoes… would we recognize an ice world’s ice volcanoes? Asteroid (16) Psyche is the closest we have to a metal world- it seems to be at least partially, nontrivially rock. Would volcanoes on Psyche reflect a metal interior, or does the rock fraction create some hybrid, or maybe something else we haven’t even imagined? Courville et al. do not merely hypothesize: considering the last magma (?) upwellings to flow on Psyche, they produce testable outcomes. Those magmatic deposits, if liquid alloy, may have frozen into place with a given magnetic field. If so, the Psyche mission’s magnetometer may pick up that signature.
This is what science looks like, not (most) science fiction, nor scientism from phonies. If your idea is not testable (even if it would require new technology for the test), it’s a story. Just a story. And let’s not forget that some stories are so freaky, we can barely conceive them. Psyche itself- a body a hundred miles across, made of a natural stainless steel- would have seemed farfetched to a prior generation. A generation before ultra-powerful radar and other observations homed in on a conclusion, a mind-boggling conclusion: our Solar System contains what appears to be a core of a planet, stripped somehow of the rest of the planet.
