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... 😱

New #Euclid image drop from @esa.int and @ec-euclid.bsky.social! 😍

Meet LDN 1641, a ‘dark cloud’ about 1300 light-years from Earth, observed by Euclid back in 2023 to test its guiding systems. ⬛️☁️

Please bear with us as we take a short break from mapping the Universe to turn our attention to pumpkin carving…

#DarkMatterDay #Halloween 🎃

We’ve got more #HumansOfEuclid for you to meet! 🕵️ 🌌

Get ready for the Leiden Entries, beginning this Friday, where we’ll feature some of the scientists we caught up with earlier this year at the @ec-euclid.bsky.social meeting. 🇳🇱

…did someone say bonus content? 🔎 #PetsOfEuclid

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…? 🚗

And while we’re at it, why not simulate a Universe too? 💻

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! 🔎

Get hands on with the Zooniverse’s @galaxyzoo.org and become a citizen scientist. 🌀

You can get up close with Euclid’s first piece of its map of the Universe! 🗺️

Take a whistle stop tour of @esa.int’s Euclid mission exhibit at this year’s GoodWood #FestivalOfSpeed with James, an Outreach Co-ordinator at The University of Edinburgh… (1/6) 🧵
