Two Forming Worlds researchers are at Origins 2026 in Paris this week, the ISSOL astrobiology conference at the Muséum national d'Histoire naturelle.
Emeline Decocq (Kapteyn PhD) is asking what the surface of the Hadean Earth was like 4.4 billion years ago. Using grids of our open PROTEUS model, she finds that a more oxidised interior outgasses more greenhouse gas, often leaving the young Earth too hot for a stable ocean. That sits awkwardly with Earth's oldest zircon crystals, whose oxygen isotopes are usually read as evidence that liquid water was already around. So which gives: have we been reading the zircon record wrong, or are the models missing something fundamental about the early Earth?
Anna Grace Ulses, a PhD student in Josh Krissansen-Totton's group at the University of Washington and visiting the lab for two months, asks when oxygen is a false alarm for life. On worlds with little background gas like N2, the atmospheric cold trap weakens, water vapour climbs high, sunlight splits it apart, hydrogen escapes, and O2 piles up with no biology at all. Worth keeping in mind for the Habitable Worlds Observatory.
The earliest Earth, and the risk of mistaking a lifeless world for a living one. 🌍

Two new master's graduates in the Forming Worlds Lab! 🎓 Congratulations to Lorenzo Cesario and Ioannis Panagiotou, who both defended their MSc theses today at the Kapteyn Institute, University of Groningen, with excellent work.
🔭🌋 Lorenzo worked out how ESA's upcoming Ariel mission can best observe ultra-short-period super-Earths, rocky worlds racing around their stars in under a day, using our PROTEUS model with TauREx to predict the atmospheric signals Ariel could catch. Co-supervised by Quentin Changeat.
🌋⚛️ Ioannis studied sulfur photochemistry as a bridge between a hot rocky planet's molten interior and its atmosphere, showing that photochemically-produced SO₂ is a JWST-detectable fingerprint of the mantle's oxidation state (PROTEUS + VULCAN). Co-supervised by Shang-Min Tsai and Harrison Nicholls.
Both theses are now being prepared for publication, we'll share more once the papers are on arXiv. Huge congratulations, both!

That's a wrap on Exoplanets 6 in Porto! 🇵🇹
The Forming Worlds Lab brought four posters to Porto this week, all sharing one thread: using our open-source PROTEUS model to link what happens deep inside a rocky world (its magma ocean, redox state, outgassing and escape) to the atmospheres JWST can actually measure.
🪐 Emma Postolec: how a young planet's air is set by the tug-of-war between gas escaping to space and volatiles locked into its cooling magma ocean.
🪐 Imre Kisvárdai: on the warm sub-Neptune GJ 9827 d, testing whether its JWST "steam world" atmosphere holds up. Its low density instead points to a hydrogen-rich, reduced world.
🪐 Mariana Sastre: how a mantle's oxidation state reshapes melting, and the atmosphere a super-Earth like GJ 1132 b outgasses. https://arxiv.org/abs/2606.20249
🪐 Harrison Nicholls (now at Cambridge, former co-supervised PhD from Oxford): L 98-59 d, a super-Earth that kept a deep magma ocean for billions of years, with photochemistry explaining its JWST sulfur signal. https://arxiv.org/abs/2507.02656
Until next time, Exoplanets Conference Series! 🔭

Hello, and welcome! 👋
We're the Forming Worlds Lab at the Kapteyn Astronomical Institute, University of Groningen. We study how rocky planets form and evolve, and what makes a world habitable, from early magma oceans 🌋 to the atmospheres of distant exoplanets 🪐. We model planetary interiors and atmospheres together, and we build the open-source PROTEUS framework our science runs on, in the open. 💻
Over the coming days, we'll introduce our group members one by one, and the research projects each of them leads.
After that, expect regularly:
🪐 the wonder of rocky planets and alien worlds

#PPOD: This stunning false-color view of Saturn's moon Hyperion reveals crisp details across the strange, tumbling moon's surface. Color differences could indicate variations in the composition of surface materials. The view was obtained during Cassini's close flyby on Sept. 26, 2005.

#PPOD: Taken by the Japanese spacecraft Hayabusa during its close approach in 2005, this very detailed view shows the strange peanut-shaped asteroid Itokawa. The 500-meter "rubble pile" asteroid features distinct smooth surface regions, such as the MUSES Sea. These areas are formed by seismic jostling that causes size segregation and erodes impact craters. Credit: JAXA

Earth, Sweet Earth ( Science For Everyone) by Ekaterina Radkevich
The book is based on the author’s impressions of her numerous expeditions in the many countries. It is a fascinating narrative rather than a mere record of facts irrespective of how scientifically valid they can be. The book is bound to be appreciated as a piece of absorbing reading by anyone who cares to increase the scope of his or her competence about our sweet home of a planet that must be saved from destruction at all costs.
Ekaterina Radkevich, Corresponding Member of the USSR Academy of Sciences, is one of the most distinguished geologists whose works are well known in her own country and in many other parts of the world. The overwhelming success of her publications is chiefly due to her indefatigable practical activity in the USSR and elsewhere and her unflagging interest in theoretical research which she has been conducting for quite some time at the Institute of Geological Studies in the Far East (Viadivostok).
Note: This book was the last remaining volume in the Science for Everyone Series! This completes volume the SFE series in English.
Many, many thanks to Hassaan Ali who purchased and posted this book to us to complete this series. Much appreciated help!

Running left to right near the terminator is Cashmere Sulcus, and extending north towards the limb is Labtayt Sulcus. Mosul Sulcus is near the left limb. The moon's south pole is in winter night.

#PPOD: Jupiter's moon Europa was captured by the JunoCam instrument aboard NASA's Juno spacecraft during the mission's close flyby on Sept. 29, 2022. As with our Moon and Earth, one side of Europa always faces Jupiter, and that is the side of Europa visible here. Europa's surface is crisscrossed by fractures, ridges, and bands, which have erased terrain older than about 90 million years.

Light curve (Planetary science 🪐)
In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y-axis and with time on the x-axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid variables, other periodic...

Dr. Kimberly Bott received her PhD from the University of New South Wales, working on exoplanet polarimetry (observation and computational modeling). Subsequently, she held postdoc positions at the Virtual Planetary Laboratory and UC Riverside.
Currently, Dr. Bott is investigating the observability of terrestrial exoplanets in polarized light with contemporary and near-future telescopes and how the method might be used to map those worlds.

The "Pink Planet" (GJ504b) is an extremely cold planetary-mass companion located 57 light-years from Earth that possesses an atmosphere enveloped in salt clouds. Roughly 25 times the mass of Jupiter, the object sits near the boundary between giant exoplanets and brown dwarfs.
