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...

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...

I’m about to start my PhD, focusing on stratospheric composition feedbacks on climate and dynamics. I’ll mostly be posting about climate and chemistry-climate feedbacks, but also on subjects bridging earth and planetary sciences due to my background.

I have a background (MSc) in Astrophysics and soon in Environmental Physics (MSc). I am mostly using 3D GCMs (ROCKE-3D) to study terrestrial habitability, including interactive chemistry, with a focus on photolysis and climate.

What are geoengineering and cloud seeding, and what are their implications for future climate mitigation strategies? @karadlamb.bsky.social—research scientist at @columbiauniversity.bsky.social studying aerosols, cloud physics, machine learning—explains: news.climate.columbia.edu/2025/07/17/g...

In ~5 years, we as a species are on track to embark on an incredible era of discovery, unlocking the secrets of the planet Venus. The missions @ESA_Envision, DAVINCI, and VERITAS will reveal Venus as we have never seen her before. But why should YOU care about our sister world?

About that new paper on K2-18b, which headlines with "Scientists hail ‘strongest evidence’ so far for life beyond our solar system," evidently prodded by a Cambridge U. press release. arxiv.org/pdf/2504.12267 . It's not actually any kind of evidence for life, and here I'll give my take on the paper.

Promising hints of life found on distant planet K2-18b Scientists find new but tentative evidence that a faraway world orbiting another star may be home to life.

An astonishing headline reporting on new observations from a team led to Nikku Madhusudhan claims they’ve found ‘hints of life’ on a planet orbiting a dwarf star some 124 light years away. What’s going on? (1/n) www.bbc.co.uk/news/article... 🔭 🧪

Loss of the aging ACE-FTS and MLS satellite instruments will create a “data desert” around stratospheric composition, suggests a paper by @rosssalawitch.bsky.social et al in #BulletinAMS. Observation gaps may hinder understanding of climate change.
