Every wave carries a story. When one story ends, another begins.

On 2–3 November, the Einstein Telescope Preparatory Phase (ET-PP) consortium gathered in Barcelona for its final Annual Meeting, looking back on four years of collaboration, celebrating what we have achieved together, and looking ahead to the next chapter of the Einstein Telescope.

A big thank you to all consortium partners for this journey!

🔬⚙️ 🦆Science, technology, industry and ducks at .

The Einstein Telescope has been at the Big Science Business Forum ( ) in Maastricht this week.

Our experts Andreas Freise, Patrick Werneke, Romano Meijer, Jan Harms and Harald Lück took the stage to introduce the project and discuss some of the technological challenges involved in building the next-generation gravitational-wave observatory.

Meanwhile, at the ET booth, visitors could meet our team, discover opportunities for collaboration and join our "Duck the Vacuum" contest!

Building the Einstein Telescope will require close cooperation between science and industry. Many opportunities to get involved are already emerging through the consortia of the candidate sites.

🌍 | What's been happening across the Einstein Telescope community?

🇩🇪 Listening to the ground
In Lusatia, one of ET's candidate sites, seismic monitoring is underway at seven locations. Instruments at the surface and 240 metres underground are recording tiny ground movements to assess local seismic conditions.

🇳🇱 Sensors for ET
The Dutch consortium has reached an important milestone. Its first highly sensitive sensor prototype has been successfully tested, while Nikhef (National Institute for Subatomic Physics) has commissioned a new high-vacuum test setup. A step towards keeping ET's mirrors virtually motionless.

🇮🇹 Science meets industry
ET Italia participated in the Borsa della Ricerca Forum in Catania (19–21 October). Through the project, researchers met with companies to explore technological collaboration in fields ranging from sensors to energy and engineering.

🇵🇱 ET at CETEF'26
ET was represented as one of Europe's major research infrastructures at the Central European Technology Forum - CETEF'26 in Poznań (19–20 October), connecting science, industry and innovation.

💫 ET governance
The 15th meeting of the ET Board of Governmental Representatives (BGR) took place in Rome. On 20 October, delegates also visited the GSSI - Gran Sasso Science Institute and INFN's underground Gran Sasso National Laboratories. The BGR will play an iportant role in deciding ET's future location.

🔜 Next stop: Maastricht!
This week, from 27 to 30 October, ET will be widely represented at Big Science Business Forum 2026 ( ), one of Europe's most important events bringing together major research infrastructures and high-tech industry.

🔭 Einstein Telescope heads to Dublin!

ET is joining the AI in Science Summit (AIS26) at University College Dublin, the flagship EU conference on putting the European Strategy on AI in Science into action, where Gianluca Inguglia, ET researcher, after reviewing the status of the field, highlighted the importance of AI for a crucial project as ET.

Why AI? ET will be 8-10 times more sensitive than today’s gravitational wave detectors and will generate enormous amounts of data. AI is already helping search LIGO/Virgo data for black hole and neutron star mergers, and it will be essential for ET.
That’s why the ET Collaboration has launched AI-for-ET, a new division, coordinated by G. Inguglia and T. Andric, that connects efforts across all boards, explores agentic AI and advanced ML, and is preparing a dedicated LLM. 🤖

Our goal is to put ET at the forefront of responsible AI in European science, ready to uncover the deep secrets of the Cosmos. 🌌

The ground is never completely still - even when it seems quiet... But what does that mean for the Einstein Telescope?

Meet Shi Yao, our researcher and research associate at Technical University of Dresden, currently based at Karlsruher Institut für Technologie (KIT), with a background in geophysics and computational seismology.

Since joining Einstein Telescope in 2025, Shi has been modelling seismic waves and the tiny changes in gravity they produce - disturbances that can affect the telescope's sensitivity.

💬 “I started out using seismic waves to understand the Earth. Now I use that experience to help ET listen to events across the universe. For me, the most exciting part is the connection between geophysics and astrophysics: seeing how knowledge and methods developed to study our own planet can help us explore the universe."

🌎 Beyond research, Shi enjoys travelling, discovering new cities and countries, and occasionally swapping adventures for a quiet evening with a good film.

Big Science cannot be built alone.

Thats why the Einstein Telescope will be at the Big Science Business Forum 27-30 October. Discover more about the opportunities the Einstein Telescope can bring for industry by attending one of the talks, or visit our booth!

On October 7, 2026, the Geometry Comparison Report was submitted to the Einstein Telescope Board of Governmental Representatives.

More than 200 experts from over 20 research institutions contributed to the report over six months. The Einstein Telescope Organisation coordinated the effort.

The document covers site-independent information on all relevant aspects of the potential geometric configurations. It doesn't conclude which configuration is better. Instead, it provides consolidated information to support that decision.

Across the candidate regions, work is moving forward: underground, above ground, and together with local communities.

📍 Sardinia
🔹 At Sos Enattos, construction of ET-SUnLab - the Einstein Telescope Sardinia Underground Laboratory has officially begun. The new multidisciplinary centre will support ET R&D, low-noise physics, geophysics and astronomy, as well as education and outreach.
🔹 Community engagement continued: “Einstein Telescope Meets the Residents” reached Oniferi, while ET researchers and communicators joined activities across Sardinia.

📍Euregio Meuse-Rhine
🔹 The ET-EMR Project Office presented new underground seismic-noise measurements from Hoof and Beusdael. The results strengthen the geological assessment of the investigated corner points; subsurface measurements from Asse are still pending.
🔹 The region is also taking a closer look at a possible L-shaped ET configuration. After an earlier desk study identified a possible trajectory, the project team will now investigate whether such a layout is physically feasible. This is important because both triangular and L-shaped configurations are being considered in the preparation of future ET site proposals.
🔹 On 27 September, a participatory exhibition in Montzen, Belgium, invites residents to explore ET’s possible impact on the landscape, infrastructure and local communities - through science, architecture, art and discussion.

📍 Lusatia
🔹 All 57 towns and municipalities in the Bautzen district have submitted letters supporting the region’s Einstein Telescope candidacy. The letters were handed over to the Einstein Telescope Lausitz team at TU Dresden during the mayors’ conference in Königsbrück.

What does it take to build 120 km of beam pipes for the Einstein Telescope?

ET will detect gravitational waves by measuring incredibly small changes in the distance travelled by laser beams. To make such precise measurements possible, the beams must travel through an extremely clean ultra-high-vacuum environment.

At first glance, a beam pipe may look simple - just a very long metal tube. In reality, the vacuum system of the Einstein Telescope is a major scientific, engineering and industrial challenge.

At CERN, a full-scale 36-metre pilot sector is being built and tested. Carlo Scarcia, Paolo Chiggiato and Anité Pérez explain why solutions that work over a few metres become a very different challenge when scaled to 120 km.

On 2-3 September, astroparticle physics representatives from throughout Europe met in Geneva to fine-tune input for the future European Astroparticle Physics Strategy 2027-2036.

The Einstein Telescope was included in the draft roadmap that served as input for this meeting, referred to as the next major flagship project for gravitational-wave astronomy, and recognised for its value for multi-messenger astronomy and role in the full astroparticle physics landscape. In the community survey feeding into the roadmap, the Einstein Telescope was also the most frequently cited next-generation infrastructure to be included.

During the meeting, the Einstein Telescope, represented by Michele Maggiore, featured prominently in the session on multi-messenger astronomy.

The final APPEC roadmap 2027-2036 is expected to be delivered by the end of this year. A moment to look forward to!
