After a long and tedious ascent I finally made it to Monte Troodelöh - Cologne’s highest mountain at a whopping altitude of 118 m. #cologne

Fantastic news that my colleague Amina Helmi, from Groningen Univ., won this year's #Kavli Preis in astrophysics! She did great stuff in identifying streams of stars coming from smaller galaxies that were devoured by our Milky Way. Congratulations!! https://www.kavliprize.org/prizes/astrophysics/2026

Today at ESTEC, not for WAMS26, who have a much cooler poster admittedly, but we are talking about imaging black holes from space, which is not too bad either …

This weekend we went to Erfurt to present our book „Kekskrümel unter dem Himmelszelt - wie entstand die Erde“ about how the Earth was formed in the theatre. This was part of the children’s book week and we had a sold out crowd of many curious kids. Parents told us: yes, he/she is always asking questions. This is want we want to encourage: ask questions, be curious!

A conversation I had with four Canadians while out cycling in Mallorca yesterday.

They asked me what I did & I said “I’m an astronomer”.

They were amazed & said they’d never met one before.

I replied “that’s funny – I meet them all the time” 🤪

Dad jokes aside, it makes sense: there’s roughly only one professional astronomer for every million people on the planet, so the chances are slim.

And asking every astronomer to have an individual chat with a million people would be a challenge 🤓🖖

🧵 Big news for particle physics this week, and honestly for me personally too.

The CERN Council has officially adopted the updated European Strategy for Particle Physics, and the recommendation is clear: FCC-ee is the preferred next flagship collider after the LHC. 1/4

Hij leerde de taal, kent het land en werkt er als gastprofessor. Microbioloog Mike Jetten, die afscheid neemt van de Radboud Universiteit, is een nieuw leven begonnen in Zweden. Maar hij blijft nooit langer dan twee weken achter elkaar in Lund. Dan wordt zijn vrouw in het Nijmeegse verpleeghuis onrustig.
