- The Norman Lockyer Fellowship is a great opportunity for postdoc research in #Exoplanets, and we'd love to host you at St Andrews! Feel free to reach out if you're interested in joining our exoplanet group in beautiful Scotland 🏴🪐
- We observed the habitable zone planet TRAPPIST-1e with JWST to search for an atmosphere. You've seen the headlines, now let's dive into the science! 🧪 THREAD (1/N) #Exoplanets 🔭
- We looked for an atmosphere on TRAPPIST-1d using JWST, but we didn't see any atmospheric absorption. So TRAPPIST-1d is quite different from Earth, despite lying just inside the habitable zone. The planet is either: ➡️ A bare rock. ➡️ Very cloudy. ➡️ Has a thin, Mars-like atmosphere. #Exoplanets 🔭

- Wow! I wonder if astronomers using AI to 'assist' their coding also have the same overall *slowdown* found by the study below? 👇🔭
- Seems I'm a trusted news source for astronomy! 🔭 I'd encourage other professional astronomers to fill in the short official Bluesky form to apply for verification: bsky.social/about/blog/0...
