  • Exploratory borehole in Lusatia

    On 29 April, representatives from the federal and Saxon parliaments, relevant ministries, the region, and the scientific community visited the first exploratory borehole for the Einstein Telescope at the potential site in Lusatia. They were briefed on the current status, ongoing progress, and upcoming steps.The borehole, located in Hoske near Wittichenau, is being used to investigate the geological characteristics of the Lusatian granite and to assess the site’s suitability for the Einstein Telescope. It is planned to reach a depth of 300 metres and will be equipped with state-of-the-art sensors for long-term monitoring. Drilling has currently reached a depth of around 85 metres. The project is financed through federal funding.…

  • First International Latin American Conference on Gravitational Waves: 10 years since first detection September 15–19 2025 at INPE Sao Paulo

    First International Latin American Conference on Gravitational Waves: 10 years since first detection September 15–19 2025 at INPE Sao Paulo A decade ago, science witnessed an extraordinary milestone: the first direct detection of gravitational waves, predicted by Albert Einstein in his Theory of General Relativity in 1915. These ripples in spacetime, generated by extreme cosmic events such as black hole mergers, remained merely a theoretical prediction until September 14, 2015, when the LIGO (Laser Interferometer Gravitational-Wave Observatory) experiment captured this historic signal.

  • The Science of ET – Blue book published on arXiv, with large German contribution

    26.05.2025 With the Blue Book, members of the ET Collaboration present a comprehensive discussion of ET´s science objectives, providing state-of-the-art predictions for the capabilities of ET in both geometries currently under consideration, a single site triangular configuration or two L-shaped detectors.  The Blue Book is a milestone paper of the ET Collaboration and a major deliverable of the European ET-PP project. Nearly 200 key contributors have worked on this comprehensive ~600-page study, the result of dedicated efforts by the ET Collaboration´s Observational Science Board, coordinated by Marica Branchesi, Archisman Gosh and Michele Maggiore.

  • The German ET Community Meeting in Hamburg

    31.01.2025 The German ET Community Meeting in Hamburg The Science City Hamburg Bahrenfeld hosted the German ET Community, with more than 150 in-person participants underwriting the strong enthusiasm of the German community to work towards the realisation of the Einstein Telescope and the maximisation of its science. Highlights of the meeting included the keynote talk by Samaya Nissanke about Multi-Messenger Astrophysics today and in the ET era and talks about the status of ET and the ET Project by Harald Lück and Andreas Freise – and the social dinner on the Cap San Diego museum ship, which allowed the hosting city to showcase their strong maritime tradition.

  • ERC Synergy Grant: Making sense of the unexpected in the gravitational-wave sky

    The Max Planck Institute for Gravitational Physics is one of the four partners in the international consortium GWSky, which the European Research Council has awarded 12 million euros to develop a deeper understanding of gravitational waves. Existing and future gravitational-wave detectors will be capable of observing signals with such precision that they may reveal possible deviations from Einstein’s general theory of relativity and the standard model of particle physics. To fully exploit this unique instrumental capability, fundamental advances are required in the theoretical description of black holes and their dynamics, the gravitational waves they emit, their cosmic environment, and the physics beyond the standard model. To provide the necessary theoretical…
