Sad but pleased to release today our homage to LIGO’s wonderful Rai Weiss, who passed away in September just shy of his 93rd birthday. It is Episode 10 of our 9-year @ligo.org YouTube video series. In our last interview, he insisted that @NSF “is the hero of LIGO.” 🧪

More discoveries to look forward to, including more overlap with Rubin observations! 🔭🧪
🔭Our fourth observing run is due to end on November 18. However, we now expect to have a 6 month observing run in 2026–27 to begin in the late summer/early fall of 2026, with detectors participating as available
