Clouds and Clarity: Revisiting Atmospheric Feature Trends in...

Over the last decade, precise exoplanet transmission spectroscopy has revealed the atmospheres of dozens of exoplanets, driven largely by observatories like the \textit{Hubble} Space Telescope....

We've long known that clouds and hazes can totally block our view of specific gas absorption signatures in HST/WFC3 spectra, and understanding what's blocking these atmospheres and why has been a major focus of exoplanet atmospheric microphysics.
