Weird New Planet Retained An Atmosphere Despite Its Nearby Star’s Relentless Radiation
A rare exoplanet that should have been stripped down to bare rock by its nearby host star’s intense radiation somehow grew a puffy atmosphere instead—the latest in a string of […]
![Pyrite sulfur δ34S values as a function of the natural logarithm of pore water sulfate concentration (r2 = 0.52). Colors correspond to TOC concentration. The solid black line is the line of best fit, with the equation y = −8.4ln([SO4]) − 3.4.
