#ET_young #ET_team Meet Carlo Scarcia: since 2021 he’s been designing the ET beam pipe vacuum system, cutting costs with smarter materials & methods. Now leading vacuum tests at the ET pilot sector at @cern.bsky.social. @rwth.bsky.social

ETO’s 3rd General Meeting took place in Isola d’Elba 🇮🇹 — a key moment to reflect on progress, strengthen collaborations & set the course toward the #EinsteinTelescope. ETO is the organisation coordinating the design, planning & implementation of this next-gen observatory. #ETO2025

🌌 Ten years ago today, gravitational waves were detected for the first time. Now, the LIGO–Virgo–KAGRA network is celebrating the anniversary with its clearest detection yet: GW250114, a black hole merger that confirmed Hawking’s Black Hole Area Theorem. #GW10Years

The LVK collaborations released GWTC-4.0, adding 128 new #gravitationalwave events from O4a, including the most massive black hole merger yet. Explore the data and interactive plots here: media.ligo.northwestern.edu/gallery/mass...

With deep sadness, we mourn the passing of Nobel laureate Rainer Weiss, whose vision shaped gravitational wave science and inspired generations. His recent contributions to the ET will continue to guide us. Our condolences to his family, friends, and community. Photo credits: MIT/Bryce Vickmark
