Measuring cosmic distances with the cosmic distance ladder: a tutorial
Nowadays we know the distance to the moon, the other planets in our solar system, the sun, nearby stars, far-away stars and other galaxies. But how?
**📍 The location of this session might change, please check here again before the session starts. 📍**
Instead, we know these distances by a wondrous interplay of theory and observations known as the cosmic distance ladder, where earlier rungs in the ladder unlock later rungs.
No prerequisites needed. You can try some of the discussed ideas at home. We will also touch on an error committed by the ancient greeks -- which was repeated in the 20th century, until Henrietta Swan Leavitt saved the day.

If you are neurodivergent or looked into the topics ADHD and Autism this might be the session for you. Unsure? No worries. Curiosity is enough to participate. I'll bring some fidget toys, talk a little about stimming and accessibility for neurodivergent minds. Please bring your own topics, life-hacks and toys so we can learn from each other! *CN:* Attendees might want to raise topics that can be triggering. These can be discussed in smaller groups where everyone is okay with it.
