  1. 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.

  6. 🌖🔭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.
