Back on Earth, our planet's atmosphere and magnetic field work to protect us from the more harmful effects of this space weather. Instead, some of us Euclideans got to see the beautiful northern lights in action - even in light polluted areas! 😍

And, thankfully, space agencies regularly monitor the Sun using satellites so that we can anticipate incoming space weather events like this. Here's a view of last week's incoming storm from the Solar and Heliospheric Observatory (SOHO)... 🕶️

But those are no snowflakes. Instead, Euclid's detectors are being bombarded by the very same particles that caused us on Earth to see the aurora. Instead of a spectacular light show, Euclid sees a cascade of cosmic rays! ⚡️

Remember that lovely aurora last week?
Well...um...this is what Euclid saw... 😱

So that’s Euclid at #FOS 2025. We hope to expand our outreach programme in the coming years, improving access to the dark universe for the public along the way. Where would you like to see us next time…? 🚗

You can become the matter in between Euclid and the background galaxies, distorting the light as it travels towards the telescope and creating a gravitational lens! 🔎
