"However, even a totally molten planet may not be able to explain the observation of the most extreme low density planets. But on this the research team also has a proposition: Molten planets early in their history can outgas large atmospheres of volatile species that were originally trapped inside the magma in the interior of the planet. This could explain an additional decrease in the observed planetary density. The James Webb Space Telescope (JWST) should be able to distinguish such an outgassed atmosphere on a planet around a cool red dwarf if it is dominated by either water or carbon dioxide."

More reason for onlookers to anticipate the launch and function of the JWST.

Well we've learned about the evolution of stars and galaxies by comparing large samples of both at different points in their respective life cycles. We will soon be able to do the same with planets.

Since the lifetime of a melty proto earth is short, it's going to be quite the trick to find one.
