A process called photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized exoplanets can provide insight into and characterize which mechanisms drive this evolution and at what times they dominate. AU Mic b is one such exoplanet, slightly larger than Neptune. During one orbit observed with the NASA/ESA Hubble Space Telescope, AU Mic b looked like it wasn’t...
