Across the vast distance separating us from the star WASP-121, astronomers using the James Webb Space Telescope have encountered a molecule that should not exist where they found it — methane, persisting on the nightside of a world where even iron exists as vapor. The discovery, led by Thomas Evans-Soma and colleagues at the Max Planck Institute for Astronomy, suggests that WASP-121b's atmosphere is driven by vertical winds powerful enough to continuously replenish what the heat perpetually destroys. In finding what the models did not predict, the team has not simply added a data point — they
