Sad day for the Belgian carbon footprint: the new government confirms the replacement of nuclear plants by new gas plants for 2025. Check out the expected impact on the electricity mix as foreseen by the Federal Planning Bureau. How can that help address the climate crisis?

[Aditya M Arabhavi @adityamarabhavi]

I'm happy to share that my first PhD paper was published today in @ScienceMagazine, featuring the analysis of the #jwst spectrum of a planet-forming region around a young star revealing an extremely carbon-rich gas composition. The paper: https://t.co/OB2757IaJY #ScienceResearch

[ULiège Research & Innovation @ULiegeRecherche]

An international team led by @adityamarabhavi used #JWST to reveal the richest chemical diversity observed to date in a protoplanetary disc and improve our understanding of the diversity of planetary systems. Proud to be part of it ! @Valentin__C

[European Research Council (ERC) @ERC_Research]

In order to ensure Europe’s competitive edge in global science and technology, the ERC Scientific Council calls for a doubling of the budget of the next EU research framework programme (FP10) and maintaining the ERC’s independence.

[Polychronis Patapis @C_Patapis]

Read our latest #research on the spectrum of one of the coldest brown dwarfs taken with @ESA_Webb @NASAWebb published in @Nature! I co-led this work together with @paulmolli and @David_Barrado and contributions from the awesome MIRI GTO team! Cool story by @ETH_physics 👇

[Olivier Absil @AbsilOli]

Great stuff from the whole MIRI-EU exoplanet GTO team! Proud to be part of it.

A team of scientists has successfully measured the isotopes of #ammonia in the atmosphere of #WISEJ1828. This study demonstrates that the isotopic abundance of ammonia can be used to study the formation of giant gas planets. @Nature

1/7 Amazing story about citizen science & why you should make your data public, a🧵... @Valentin__C @astroclaui @MonashAstro

[ULiège Research & Innovation @ULiegeRecherche]

Located 374 light years away from Earth, #HD169142b has been confirmed as the third #protoplanet to date by a team of researchers from @UniversiteLiege and @MonashUni. @OxUniPress @Valentin__C @ESO @AbsilOli @frsFNRS - https://t.co/tDcdLRr4Ss

Registrations open for the VLTI school in Budapest: https://t.co/6kf0EKGlJM

[Olivier Absil @AbsilOli]

@LeoBurtscher Hey I just got that one too! Maybe they found a METIS mailing list? ;-) At least the content was kind of funny.

[Gilles Louppe @glouppe]

📢New paper: Neural Posterior Estimation for Exoplanetary Atmospheric Retrieval -- or how to apply simulation-based inference to study the atmospheres of exoplanets? A team effort with @Vasist47 @FrancoisRozet @paulmolli @AstroEvert and @AbsilOli 👇🧵 https://t.co/0XM4dXGvwu

[Astronomers for Planet Earth @Astro4Earth]

.@ultracricket and @ClimateHuman, two very respected colleagues of ours, were sanctioned for #ClimateAction during #AGU. This is unacceptable retaliation against scientists speaking out for #ClimateJustice. Please sign the letter of support until Sat here: https://t.co/hGiCuOUwE5

[Jason Wang @semaphore_P]

Finally got around to uploading the 12-year HR 8799 time lapse onto my website. You can now download it here: https://t.co/06qpEV9fxy!

Thanks to @AstroWrt for reducing the new data (and check out his paper https://t.co/bJBlGKCcRS)

[Denis Defrère @ddefrere]

We are hiring! The SCIFY team of @IvS_KULeuven is looking for a new postdoc to work on instrumentation for exoplanet imaging https://t.co/ZfT24DzHFe

[Olivier Absil @AbsilOli]

Five 3-yr postdocs open in Belgium to work on JWST data: https://t.co/ZyEXdPow2S The 1st one (@KU_Leuven + @ULiegeResearch) aims to use a new exoplanet atmospheric retrieval tool based on neural posterior estimation, developed with @glouppe and @paulmolli (stay tuned for paper).

[Fossil Fuel Treaty Initiative @fossiltreaty]

🚨 Breaking 🚨 The European Parliament just called for nation-states to “work on developing a Fossil Fuel Non-Proliferation Treaty” in its formal #COP27 resolution.

This is a major development in the global push for a #FossilFuelTreaty.
