come see me in session P41B (right now in 213 south) or at my poster this afternoon at board 3091! I’ll be speaking about plasma waves in Venus’s induced magnetosphere from Parker Solar Probe observations #AGU2023

For decades, scientists have hotly debated whether lightning strikes on Venus. At #AGU23, don't miss LASP @CUBoulder researcher Harriet George's talk on "Non-lightning-generated whistler waves in near-Venus space." Thurs. 12/14, 8:59am in South 213-214. eos.org/articles/lightning-s…

Whistlers were a key piece of evidence in favor of Venusian lightning. New measurements question the connection.

New paper! We studied whistler waves observed by PSP during a Venus gravity assist. These waves are often attributed to lightning on Venus but we found that they were not lightning generated and were instead caused by an unknown process in the magnetotail doi.org/10.1029/2023GL105426

Non‐Lightning‐Generated Whistler Waves in Near‐Venus Space

Whistler waves were observed at an altitude of 0.39 Venus radii on Venus's nightside with planetward Poynting vector Langmuir waves occurred simultaneously with the whistlers, suggesting electron...

This implies that rates of lightning on Venus that are based on observations of whistler waves may be overestimated, and that Venus could have relatively little lightning ⚡️

This paper is the culmination of my career so far - 10 years of software development, sweat and tears - but we did it! @vlasiator @cleanorbits @KumpulaScience

I needed a day to calm from the excitement of reading my name among the newly awarded Academy Research Fellows of @SuomenAkatemia I am so happy to continue my research career here in Finland @KumpulaPhysics @KumpulaScience Looking forward to the next 4 years of #space #physics
