With the launch of the James Webb Space Telescope, astronomers can now constrain the atmospheres of cool rocky planets by analysing their thermally emitted light. However, while the low-mass host stars provide observational advantages, they also expose their planets to intense ionizing radiation that could strip away their atmospheres. Indeed, the first wave of data is consistent with a pattern of airless or thinly blanketed worlds. One of this decade’s major scientific findings will be whether these planets will herald a galaxy that could be teeming with life or further indicate the rare convergence of conditions required for an Earth-like habitat. My theoretical paper on this topic, “Novel Physics of Escaping Secondary Atmospheres May Shape the Cosmic Shoreline,” co-authored with Ray Pierrehumbert, is currently under review at the Astrophysical Journal.
