Climate science is the most significant scientific collaboration in history, and its lessons are a massive human achievement. “How We Came To Know Earth,” our new series, is a guide to the modern understanding of fundamental climate science. www.quantamagazine.org/series/clima...

Hi! Today @quantamagazine.bsky.social published a special issue on climate science, featuring stories about how Earth's climate fundamentally works that I needed to read after covering climate impacts for so many years. I hope you'll check it out! <3 www.quantamagazine.org/how-we-came-...

@marattia.bsky.social, postdoc in our group, won the Edith Alice Müller Award 2025 of the Swiss Society for Astrophysics and Astronomy for their outstanding PhD thesis in the fields of Astronomy and Astrophysics. Great achievement @marattia.bsky.social, congratulations! 🥳🎉 @kapteynastro.bsky.social

In our now-published paper we model the early history of three exoplanets to specifically study the role of tidal heating on their capacity to solidify. A physically robust feedback mechanism can keep them molten, even with relatively thin atmospheres, which may extend to lots of rocky exoplanets.

Published in #MNRAS: "Self-limited tidal heating and prolonged magma oceans in the L 98-59 system", Nicholls et al. This is Fig. 1: for the caption & to read the paper please visit academic.oup.com/mnras/articl... @oxfordacademic.bsky.social @royalastrosoc.bsky.social

Globally, roughly a third more power is being generated from the sun this spring than last. If this exponential rate of growth can continue, we will soon live in a very different world, @billmckibben.bsky.social‬ writes.

We performed an analysis of the 2024 NWO VIDI awardees. Conceived to support researchers transitioning from postdoc positions into independent scientific leadership, the VIDI has become more of a mid-career consolidation grant. Read our full analysis and recommendations: ap-net.nl/wp-content/u...

Iris' paper is now published in ApJ at doi.org/10.3847/1538...! @nichollsh.bsky.social

Hola Astro/Geo/Photo/Documentary- BlueSky community! This is my first post soooo: I’m Mariana, I’m a 2nd year PhD Student researching the geophysical evolution of Magma Ocean Exoplanets! I’m in love with volcanoes of this and other planets 🌋👑🌍

In our new paper we model the complete evolution of L 98-59 d from 'birth' up to the present day. We show that it cannot be a gas dwarf or a water world; it's a 'hybrid' planet with an H2-rich atmosphere containing H2S and SO2 (photochemistry!), and a deep magma ocean. @timlichtenberg.bsky.social

📣 Calling all rocky enthusiasts! We are thrilled to announce that the ROCKY WORLDS 4 Conference will take place 19-23 Jan 2026 in Groningen, NL 🇳🇱 This is the 4th Meeting in our series & we can't wait to see you there! Abstract submission is NOW OPEN groningen2026.rockyworlds.org/groningen-2026 🪐☄️🔭

One more week left to apply for the below advertised interdisciplinary PhD position within the context of the Dutch PRELIFE consortium! ⏩🏃‍♀️

The abstract submission for Rocky Worlds 4 is now open! groningen2026.rockyworlds.org/registration... 🌋🔭🧬😱

Just published in JOSS: 'AGNI: A radiative-convective model for lava planet atmospheres' https://doi.org/10.21105/joss.07726

Pretty much sums up it up for me.

New paper on arXiv today: "Absence of a Runaway Greenhouse Limit on Lava Planets" by Iris Boer, @nichollsh.bsky.social, and me (arxiv.org/abs/2505.11149). The runaway greenhouse limit is non-existent on molten planets (which is how planets form), questioning the general "habitable zone" concept.

Within the context of the interdisciplinary PRELIFE consortium me and Wim van Westrenen are advertising a joint PhD position on the surface water levels and atmospheric composition of the earliest Earth: www.formingworlds.space/phdposition2.... Deadline: 10th June. Please share! 🌋🌏🧬

A 9-point action plan to strengthen Europe:

I'll come back later and put some references and readings for those who want to know more. It's really important for us to learn this stuff. Some I summarised here: jksteinberger.medium.com/what-we-are-...

The neoliberal dream of fossil fuel billionaire Charles Koch was always the destruction of US democracy and the elimination of government (except for its repressive organs police, courts, prisons, military ofc), and now he has won. What now? A 🧵. 1/ t.co/FKxxmLyfce

Help us wreck his wealth? We’ll be at 95+ sales centers in five countries all this week. More events coming. Drop sales = drop share price. Elons shares collateralize his loans. We’re destabilizing those. Amplify with a repost? Teslatakedown.com #teslatakedown #teslaboycott

"We’re witnessing the self-sabotage of the United States" from @davidfrum.bsky.social www.theatlantic.com/politics/arc...

I understand why it’s important to state that science is crucial for improving + prolonging lives. But I wish people talked about discovery as being valuable on its own. In this sense science (and humanities!) are also WHY we want to prolong and improve lives. They’re the whole point of being human.

1 week left to apply to do a PhD in the new Exoplanet Atmospheres group at St Andrews 🪐🔭 Feel free to reach out if you're interested in applying!

This is a turning point. We Europeans have the power to push X into irrelevance across our continent. Freeze or delete your accounts now. Media, it’s time to stop citing X. Dozens of universities are leading the way. Let’s limit Elon Musk’s influence in 🇪🇺. #eXit #SciXit #Democracy

Our new paper on atmospheric convection on lava worlds is now on arXiv (accepted in MNRAS). We model the early time-evolution of two terrestrial-mass planets, and find that their atmospheres are not always convective. However, they can still have permanent magma oceans! arxiv.org/abs/2412.11987

Super interesting new study on convection in lava world atmospheres by @nichollsh.bsky.social today on arxiv.org/abs/2412.11987! Two main findings:

It’s really cool to see this in observations, as it’s something we proposed in a recent paper. We explain how phase curves would be optimal in breaking this degeneracy: arxiv.org/abs/2409.04386

Very cool new paper by Ducrot et al, who obtain eclipse measurements of TRAPPIST-1b at 12.8 and 15 microns. They show that getting these two data points is not enough to distinguish between a reflective surface or a hazy CO2 atmosphere: www.nature.com/articles/s41...

🚨 SPECIAL FIRST POST 🚨 Applications to @exoclimes.bsky.social (7-11 July, 2025 at @umontreal.ca) is now OPEN until Jan 24, 2025! Join us for a week of exciting talks on planetary atmospheres interspersed with ample opportunities to discuss and forge new collaborations! forms.gle/mpeZ3LXGoFb9...

Today is the first day of NOVA’s 25th anniversary celebration, and I’ll try to liveskeet most of the talks…

Threats to academic systems are not uniquely Dutch. Across the globe, we see regimes dismantling those equipped to critique them, disrupting the cosmopolitan academic space that resists nationalist and xenophobe policymaking. This calls for solidarity and even more cosmopolitan worldviews! 4/

To those outside of the Netherlands: Yesterday and today, Dutch Christian religious parties sold their souls to the right-wing government in exchange for a few dimes and now support radical and destructive cuts to the Dutch educational system. This makes this, sadly and terribly, a done deal. 1/

Exciting new paper by Mohammad Farhat yesterday on arXiv: "Tides on Lava Worlds: Application to Close-in Exoplanets and the Early Earth-Moon System", by Mohammad Farhat, Pierre Auclair-Desrotour, Gwenaël Boué, Tim Lichtenberg, Jacques Laskar (arxiv.org/abs/2412.07285). 🥳🤯

The right-wing Dutch gov is planning huge budget cuts to (higher) education. I'm posting a picture every (other) day from protests. Protests again today all over the country - in Maastricht at 14:30 @ Plein 1992. Let's fight to stop the Eppocalypse! 🟥 #DoeHetNiet #WOinActie 🟥

Excited to share that our paper on atmospheres on lava planets has been accepted in JGR: Planets! You can find it on arXiv here: arxiv.org/abs/2411.19137

PhD position available at the University of Bristol! Come work with me to model convection in sub-Neptune atmospheres! www.findaphd.com/phds/project...

I have an exciting PhD project (starting September 2025) based at the University of Edinburgh. You will study the exotic world of a Venus-like exoplanet with a focus on the atmospheric chemistry and physics: (ifa.roe.ac.uk/phds-jobs-fe...). Deadline 6th January 2025. @kenrice.bsky.social
