Our paper on PSO J318 is finally out 💪 . I want to thank all of my coauthors who made this study possible 🙇 !! It could be that we see the first cloud seeding nuclei forming at the top of the atmosphere…?

Just shared a new paper on the arXiv, led my @luiswel.bsky.social and me, on the challenges associated with detecting gases in exoplanet atmospheres. As the field pushes towards new and exciting opportunities, we thought it was time to talk about what it really means to “detect” something!

Do you want to do cutting-edge exoplanet science with JWST in a Bavarian castle?
If yes (and why would you say no???) there are still a few spots open for the Ringberg Workshop "Signal in the Noise" (Nov 17 - 21). Register here sites.google.com/view/jwst-ri...
