Euclid UK @eucliduk.bsky.social · 19/11/2025But 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! ⚡️ 1192 0
Euclid UK @eucliduk.bsky.social · 19/11/2025At the peak of the storm, the increasing cascade of cosmic rays causes the (already huge!) data files to become too large for Euclid to transmit back to Earth and you begin to see the view from some of the detectors appear to disappear entirely! 😳 2100 0

Euclid UK @eucliduk.bsky.social · 19/11/2025This led to a couple of days of unusable data. 😬 Lasting damage is done to the telescope’s sensitive detectors, but this was planned for in the mission’s design and Euclid can take much more damage still before its instruments seriously degrade. 💪 1120 0
