Wow – didn’t think I’d be in tears today, but this message sent home from Gaia as it was shut down forever today hits hard 😭

What you’re seeing is a map of the 106 CCD detectors that Gaia used to measure the positions of billions of stars in the Milky Way for the past 11 years 🛰️✨

They were turned off in a special sequence … 😕

@markmccaughrean Such amazing science!! Thank you, Gaia!

Every solar system small body project I'm involved in uses Gaia data for astrometric calibration, just one of the many science measurements made better by Gaia!
