Exoplanet atmosphere characterization is built on a foundation of lab data and chemistry. We need more reaction rates, cross sections, & line lists, at a broader range of conditions than the Solar System. Got together with Earth/planetary scientists to comment on this: www.nature.com/articles/d41...
How to understand exoplanets — space scientists call on lab-based chemists to help
Stronger links between researchers who work on Earth’s and other planets’ atmospheres, and between the experimental, modelling and observational communities, will help to interpret the astronomical da...

Fresh off the press: lightning activity in high-res simulations for TRAPPIST-1e! Just a nice little study that began as James's and Lottie's undergraduate research project. We find less lightning for higher surface pressures. It's only one model though!

ABSTRACT. Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules i

PhD project: A chiral molecule is one that can also exist in its mirror-image orientation, with the pair often having very different properties. This project will explore the environmental importance of chiral molecules emitted by the Amazon forest. edin.ac/4ilOY4v @jacquirickard.bsky.social

So excited to share our observations with everyone. Understanding our Solar System planets is key to supporting future exoplanet observations, especially at unique geometries that we can’t view from Earth!
Excited to participate in this paper by Samantha Hasler @sammyhasler.bsky.social about the ice giant Uranus: combines the power of Hubble 🔭 with the unique viewing geometry when U is detected by the New Horizons spacecraft 🚀 from WAY out in the Solar System hubblesite.org/contents/new...

My first Venus paper is out! Key findings: the Venus deep atmosphere moves really, really slowly, but it may have really, really big waves. Many thanks to my co-authors and the reviewers. 🌔🍻https://iopscience.iop.org/article/10.3847/PSJ/ad76a8
