What planets do we study? #Earth & #Mars are some of our favs, but the @JohnsonCloudLab has expanded to include small astronomical bodies like #Titan + our #Moon, and #Exoplanets. If there is an atmosphere we want to use #CloudMicrophsics to explore it! (📸: Martin Vargic)

ICYMI: Purdue University is now a host site for the 51 Pegasi b Postdoctoral Fellowship! 17 faculty mentors from @PurdueEAPS & @PurduePhysAstro pursuing amazing research in planetary astronomy - myself included for planetary atmos inclined - have been identified. More info in 🧵

The 51 Pegasi b Fellowship applications have opened for 2025, and Purdue is a new host institution! If you are a final-year PhD or 1st- or 2nd-year postdoc interested in origins of life, prebiotic chemistry, or the search for life, my lab might be a fit! bit.ly/40Mr1Mq

A bright and shining example of the suicidal absurdity of technocapitalist society occurs every year at this time, all across the country. 1/n

@AhrensScience @JonesKuma Came to say the same thing 😂

@JonesKuma That’s no moon 👀

Joining the squad of 3D printing planetary bodies 😘

@drdre4000 Love it!

And that’s a wrap on Halloween 2023. Won a contest with my costume of Diva Plavalaguna from the film ‘The Fifth Element’. Let’s see what next year brings 🥰

@stellerarts @PurdueEAPS Thank you! 🥰 It was such a fun costume to make!!

Teaching on Halloween? You know what that means! Time to make yet another atmospheric thermodynamics related costume 👀

Purdue is in here too!!

@NolanFossum I have no doubt it was a great talk! 🤩

It’s just about to start! Come on down to the first floor! #NCTMDC23

@That_Astro_Chic Thank you @That_Astro_Chic 🥰

Seeing my mentor @avblanch on this paper makes me very proud! 🫶🏽

Nitrogen is only ~3% of the atmosphere of Venus, but it holds clues to its past: the abundance can be explained only if there was a period of active tectonics, which lasted >1 Gyr before transitioning into the current stagnant lid. @PlanetaryGeodyn et al.: nature.com/articles/s4155…

Simulations produced by a Brown-led research team suggest the scorching hot and barren planet Venus may have once had tectonic plate movements similar to those believed to have occurred on early Earth. brnw.ch/21wDTBd

An exciting new study led by DEEPS researchers explores the connection between Venus's current atmosphere and surface pressure, shedding light on ancient plate tectonics. @NatureAstronomy @alexjayevans @Dan_E_Ibarra @avblanch

Scientists make the case that the Venus may have had plate tectonics making it more hospitable to life. Dr. Alexandria Johnson, of @PurdueEAPS, is part of the research team discussed in this @nytimes article. @avblanch #thenextgiantleap bit.ly/3scUGjZ

@urban_tom @elonmusk @X I feel this in my bones.

@urban_tom @PurdueEAPS Thank you! Random it popped up now but I will take it 😂 Nice AGU picture!!

Been sitting on this news for a hot second, but as of today your girl is a **tenure track** Assistant Professor @PurdueEAPS! Beyond excited to continue our exploration of clouds in planetary atmos & so very grateful for the support network that never stopped cheering me on.

@stellerarts @That_Astro_Chic @PurdueEAPS Thank you @stellerarts 💕

@johannabrown @That_Astro_Chic @PurdueEAPS Thank you @johannabrown!! 🥹
