K218b hazes? The plot thickens...! Really interesting new analysis from @ruohanliu.bsky.social just out on arXiv arxiv.org/abs/2509.10947 #exoplanets 🪐🔭🧪
Hydrocarbon Hazes on Temperate sub-Neptune K2-18b supported by data from the James Webb Space Telescope
K2-18b, a sub-Neptune orbiting in the habitable zone of an M dwarf, has attracted significant interest following observations with the Hubble Space Telescope (HST) and, more recently, with the James W...

Totally get behind this! GitHub pages was super intuitive to set up, and my very minimal html knowledge was more than up to the task with how many templates are out there! joolsclarke.co.uk if you want to check it out for inspo :)

Super exciting to get to meet so many great people at Exoplanets by the Lake III, and to get an opportunity to present a slice of my upcoming machine learning research. I had some great discussions, but if you missed me, please reach out! #exoplanetsbythelake #exoplanets
Big day for the matriarchy! 🥳 Huge congrats to the awesome Prof. Doughtery, lead on the Jupiter-bound ESA JUICE mission & STFC Exec Chair. If anyone's confused on the astro royal hierarchy: Michele and I are the astro equivalents of 🇬🇧Westminster and 🏴Holyrood 🤗 ℹ️: www.bbc.co.uk/news/article... 👩🔬🔭🧪
UK gets first female Astronomer Royal in 350 years
Prof Michele Dougherty is the first woman to be appointed to the influential post.

Finding atmospheres would be great, but not finding them would be profound! (In the case of M dwarfs) - Jacob Lustig-Yaeger #sagan2025 #exoplanets
This, but also at the same time we need to let habitability not be the only motivator for exoplanet studies and move into population level studies. There is so much to be learned from the Jovian short period planets too #exoplanets
Dr Joanna Barstow@drjovian.bsky.social · last yr.We have a grand total of 0 actual Earthlike planets confirmed in the habitable zone of a sunlike star, determining eta Earth requires extrapolation. We need to start filling in the longer period gap, even if we don't get out to the habitable zone. TESS and PLATO long period searches will help #HWO25
Super interesting investigation from Jack Davey on the effect of observation errors in retrievals. Good to know I don't have to panic _yet_, but definitely something to keep an eye on! #exoplanet 🔭 arxiv.org/abs/2507.19223
Investigating the Influence of Asymmetric Errors on Retrievals of Exoplanet Transmission Spectra
In studies of exoplanet atmospheres using transmission spectroscopy, Bayesian retrievals are the most popular form of analysis. In these procedures it is common to adopt a Gaussian likelihood. However...

So 16 y-o's can vote but god forbid they send direct messages on bluesky ooooOoo -- yh it is clear this sudden care about online welfare has come at a very convenient time for the UK government amid crack downs on those in opposition to genocide across the country
Finally got to see these new k218b retrievals from @ruohanliu.bsky.social in person! 🧪🔭🪐 #exoplanets #beacon25
If you're interested in the role of machine learning in exoplanet characterisation, and in more depth about how we can understand these methods, check out what I've been doing in room B at 15:15!! 🪐🔭 #beacon25 #exoplanets
Super exciting stuff! Ariel Data Challenge Launches today! I can't believe it's that time again already, but if you're looking for a bit of a fun coding challenge, check this out, previous years have been a lot of fun. #exoplanets 🔭🪐 www.instagram.com/p/DLhOUXEtKk...

Exciting to see these results from Jack ! Also good to know I don't need to redo my analyses _again_ 🎉
Dr Ryan MacDonald@distantworlds.space · last yr.Davey: using the real WASP-39b data we don't see any major differences or biased (good news!). So no need to re-analyse existing JWST spectra (unless there is majorly asymmetric error bars). #AllTheWavelengths

Ruohan Liu is presenting a new analysis of K2-18b with an alternative model and different results. #allthewavelengths
Excited to see any Ariel updates from Giovanna, looking forward to next week at BEACON25 hopefully as well there will be a few updates released (also nice scarf... 👀🪐)
