The application for the ESO Summer Research Programme 2026 has just opened!
It‘s a six week programme in Garching close to Munich where pre-Ph.D students can work on a hands-on project.
Working at @eso.org is a fabulous experience, so please help me spread the word ✨

Update on the atmosphere vs no atmosphere debate for TRAPPIST-1 b and c -- here's a nice and (IMO) conclusive result from Gillon and Ducrot et al.: no thick atmosphere on either planet. arxiv.org/pdf/2509.02128

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…?

The evidence for biosignatures on K2-18b is flimsy, at best
Last week, Cambridge scientists announced the discovery of DMS and DMDS on K2-18b: what they call a "surefire biosignature."
Now, cut through the hype and get to the truth.

A Cambridge-based team claims to find molecules on an exoplanet that are only produced by life on Earth. Don't fall for the unfounded hype.

K2-18b is back in the news, now with a bold claim that biosignature molecules (DMS and/or DMDS) have been 'detected at 3σ'.
Most exoplanet astronomers are extremely sceptical about these claims, let's see why (1/n).

A direct imaging claim by Lagrange+ [https://arxiv.org/abs/2502.15081](“Evidence for a sub-jovian planet in the young TWA7 disk”) - a very clear point source but only one epoch… but it’s in the gap in the disk around the star. Will be exciting to see follow up. 🔭🪐 #astrodon

Hello astronomy hive mind! I'm looking for examples of exoplanet systems where a planet has been found - say at period A - and then a later paper claims that there is no planet at period A but there *is* a planet at period B that explains the data for the original planet claim. Any pointers?
