Now, we have a joint thermal phase curve for the planets, finding no significant heat redistribution from dayside to nightside. Here are the constraints on dayside and nightside temperature (K) for the planets. Dayside is red, nightside is blue, top row is planet b, and bottom row planet c.

gorgeous new JWST spectrum of the rogue planet PSO J318 from @paulmolliere.bsky.social ! Strong absorption at 10 microns likely due to small SiO particles, acting as seeds for cloud formation arxiv.org/pdf/2507.18691

Happy to share the first paper from the SPACE Program, led by my student Angelique Kahle! she observed a hot little sub-Neptune, HD 86226c (Rp = 2.3 Re; equilibrium temp = 1300 K). arxiv.org/pdf/2507.13439
The spectrum is *really* flat ! here's the amplitude compared to other gaseous planets.

Classic astronomy ... when you have more than 6 data points, time to do a demographic study! nice work, Fu et al. :) arxiv.org/pdf/2501.02081

Awesome to see over 100 small (~10m) asteroids discovered in the foreground of TRAPPIST-1! news.mit.edu/2024/mit-ast... The original goal of our observations (and others) was to study the atmospheres of the TRAPPIST planets, but there are also many asteroids zooming by (movie cred: Sebastian Zieba)

Just, you know, hanging out with a gigantic refracting telescope. As one does. Thanks to Uni Vienna for a great visit!

Great week of exoplanet atmosphere science at the 2023 NASA Sagan workshop! All the talks are online in case you missed them :) https://www.youtube.com/@SaganSummerWorkshop/videos
