This artist's illustration shows the internal structure of a lava planet in a cold state, showing a day‑side magma ocean overlain by a mineral atmosphere. The arrows indicate the direction of heat transport within the planet’s interior and the thermal radiation emitted from its night side. Credit: Romain Jean-Jaques (Instagram: @romainjean.jacques)
