🌍☀️ Scientists at #ArizonaState and #Caltech used the #JWST to produce the first weather report for WASP-94A b, a gas giant 700 light-years from #Earth.
The #planet has two different #weather sides: a morning edge with #clouds made of vaporized #rock and an almost cloud-free evening edge, driven by temperature differences and powerful winds.

The revised analysis does not fully rule out #Europa plumes, but it substantially weakens the original #HST #Lyα evidence. After accounting for Europa’s extended #hydrogen #exosphere and improved background modeling, the previously reported localized excess emission is no longer statistically compelling.

🌖🔭Roth, Retherford, Saur et al revise their 2014 paper: In a reanalysis of 23 #HST/ #STIS #Lyα observations, the authors revisit & revise their earlier #Europa water plume interpretation.
With improved disk positioning & inclusion of a #hydrogen-#exosphere model, the previously reported localized Lyα excess becomes substantially less significant & may be consistent with noise. The data instead robustly support a persistent atomic H exosphere.
