I‘ve started interviewing cool people for @egu.eu again! This is Kaja! 👇

🌌 What a night at Astronomy on Tap Bern! Corinne Charbonnel and Mark Gieles, researchers of the ISSI International Team 636, had us listen to the universe's most dramatic events (literally!). Thank you all 💙, and see you at the next one! 🔭 #AstronomyOnTap#Bern#Astrophysics

Mendeleev dreamt up a table. 150 years later, we are still filling in the gaps – and finally colouring it properly. [No rainbow gradients were harmed.] 🧪⚛️ s-ink.org/discovery-of... #sciart 🐡 📊

🌌 How fast is the Universe expanding? A new international study, born from an ISSI Breakthrough Workshop, offers the sharpest answer yet: PRESS RELEASE: www.issibern.ch/hubble-const... 🔭 @eso.org @nasaupdates.bsky.social @stsci.edu @noirlabastro.bsky.social @mpi-astro.bsky.social and others!

There are many colorblind-friendly, perceptually uniform colormaps (e.g., cmocean, @fabiocrameri.ch), yet many papers at @agu.org still use rainbow variants. Not just aesthetics — they can create artificial structures (see plot). Better options exist.

🎬 Meet Dr Sara Gasparini, space physicist and aurora researcher, and former ISSI Visiting Scientist ahead of leading her own ISSI International Team. youtu.be/NgQUyzfJlw4 #ISSIcast #auroras ✨🔭

Your favourite graphic just got updated: Here’s the colour-vision deficiency friendly periodic table of elements: s-ink.org/periodic-tab... Now including electron configurations and featuring a refined design. ✨

I had the pleasure to (finally) meet @franckghomsi.bsky.social in person and talk to him about his work, Global South perspective, and academia. 😇

QGIS users: ATTENTION! We now have a convenient #QGIS plugin to integrate the latest version of the Scientific colour maps directly into the style manager: plugins.qgis.org/plugins/scie... Shout-out and big thanks to Silvain Théry. ⭐️ Happy mapping, everyone! #UseBatlow 🐡

In what format do you do the best science? - Rhetorical question, because I see the answer day in, day out 👇

I had a school class over at the International Space Science Institute. 👫👭👬👫👭 Here‘s what I learned from their feedback about Science Communication. 👇

I had the pleasure to talk to these two inspiring and kind (truly the best combination!) space scientists and witness first hand how science bridges the generational gap.

For the latest ISSIcast, I talked to Ben Poulter, former Deputy Director for Greenhouse Gas Measurements and Monitoring at the White House Office of Science and Technology Policy. 👇

Assemble your dream team and come collaborate at ISSI! Free coffee, meals, and hotel room included. 💥

Persistent river heatwaves are emerging worldwide under climate change By the 2090s, nearly half of the world’s rivers could be in a year-round heatwave state, threatening ecosystems and communities, disproportionately in low-income regions, such as the Congo basin www.nature.com/articles/s41...

From Earth’s warm heart to its surface glow, Heat flows like time, constant in its flow, ~46 TW from below. New year, new graphics to make hidden mysteries known, Open, clear, and accessible to now call our own! ❤️‍🔥 s-ink.org/earth-intern...

What happens when world-class solar scientists meet a cozy bar in Bern? ISSI teamed up with Astronomy on Tap Bern for an unforgettable evening with 3 amazing talks, a full house, and even a debate on whether the heliosphere is shaped like a croissant 🥐, or not. www.issibern.ch/astronomy-on... ☀️🔭

The latest version of the Scientific colour maps is now available for ArcGIS Pro, thanks to Craig Williams. 🫶 Download them here: www.arcgis.com/home/item.ht... @arcgispro.bsky.social #UseBatlow

✨ Meet @issibern.ch at the exhibition of #EPSCDPS2025, discover their amazing science and space projects!

Come say hi, if you are at #EPSCDPS2025! 👋

It is the word of the town. ISSI is on tour again. If you are too, come say hi during this week’s #EPSC2025 here in Helsinki! – You know where to go, just follow the blue. @europlanetmedia.bsky.social @spacemarschall.net @kokotanekova.bsky.social @fabiocrameri.ch #EPSCDPS #EPSC-DPS2025

I wrote a piece for @egu.eu about academic evaluation and how the resulting incentives for academics are destructive. I think it can be done better. 🕸️ But only if you want it, too. 🫶 blogs.egu.eu/divisions/sm... #Academia #AcademicEvaluation #ScienceMetrics #ProAc

During the last 30 years, our telescopes improved and became more. We discover more of what lies beyond our sky. Exoplanets, planets outside our solar system, might host life or tell us more about our own planet. Here are 4999 of them perfectly to scale. 😮‍💨

Lovely paper out by Benjamin Hatchett about colour consistency in pyrocartography 🔥🗺️: doi.org/10.5194/gc-8... #UseBatlow

Such a great short course on different aspects of #DataViz at #EGU today! The room was absolutely packed — people were sitting on the floor (hey, @egu.eu maybe consider a bigger room next time?😉) And it's always a pleasure attending @fabiocrameri.ch's presentations! #endrainbow, yep.

I am looking for some first-time attendees of the EGU General Assembly 2025 …to answer some easy questions in another ‚We Are EGU’ video (see youtube.com/playlist?lis...). If you know anyone interested, please DM me or send me an email with their contacts. Thank you!

Nice to hear, Andrew. 😇 ⚠️ Two points to clarify: 1) Turbo is NOT perceptually even (don’t know why people think it is – research.google/blog/turbo-a...) 2) Our preference for certain colours cannot trump the argument for scientific accuracy or inclusivity (Not sure why people think it does).

Great news! The scientific figure design cheat sheet that @fabiocrameri.ch and I created for @wearetektonika.bsky.social is now available in Español 🇪🇸and Deutsch 🇩🇪 Use it, share it, and make beautiful figures!

🐡

Do you make scientific figures? Then check out this handy little guide that @fabiocrameri.ch and I have put together for our editorial piece in the newest volume of @wearetektonika.bsky.social ✏️ The figure is available from @s-ink.org - download it, share it, use it!

@drlperezdiaz.bsky.social and I wrote a little mighty piece on how #geoscience visuals need to be different today than 60 years ago.

Don't use red and green data lines/surfaces in the same panel please #chemsky. It can be difficult for some colorblind readers to differentiate them. I've accepted (in principle) 2 papers today, and both sets of authors were asked to remove red/green colour contrasts www.nature.com/articles/d41...
