The @ligo.org – Virgo – KAGRA Collaboration published today a new catalog of gravitational wave events that adds 161 events to the collection, bringing the total number of gravitational wave signals detected to date to 390 🤯

In a paper published today the @ligo.org – Virgo – KAGRA (LVK) detector network describes a new trick up its sleeve to improve the instruments’ sensitivity to gravitational waves: it’s called Astrophysical Calibration and it plays a role similar to auto-tune in music production 🎵

Today is World Art Day, created by UNESCO 🎨 In recent years, we have fostered dialogue between the field of gravitational-wave science and contemporary art, welcoming many artists who have visited Virgo and created works and projects inspired by our themes ✨ 📷Artwork by Pedro Torres

3,000 students from all over the world have visited Virgo remotely during this school year 🤯 This was made possible by the guided tours organised as part of the European project PICO – Physics for All by EGO, with the support of Ellinogermaniki Agogi.

The European Union has approved funding of approximately €350,000 for the PICO – New Horizons project through the MSCA and Citizens 2025 call! (1/6)

April Fools’ Day 🐟 this post was an April Fools’ Day joke, the warp drive remains science fiction for now, but gravitational wave science will continue to let us explore the universe through present and future detectors 🌌

A new patent, filed by the European Gravitational Observatory, will turn the warp drive – the technology that allows the starships in Star Trek to travel faster than the speed of light – into reality 🚀

Why is the @ligo.org - Virgo - KAGRA meeting so important? Why do people from all over the world travel to meet in person? Let’s hear it from the participants of the meeting that took place in Pisa this month 🗺️

We had a chat with Marie Anne Bizouard, @cnrs.fr researcher, just after her election as spokesperson of the Virgo Collaboration, during the @ligo.org - Virgo - KAGRA Collaboration meeting in Pisa 💬 Here’s what she said about this role and the future of Virgo 🎤

We are happy to announce that Marie Anne Bizouard, researcher at @cnrs.fr in Nice, has been elected as the new spokesperson for the Virgo Collaboration, with effect on May 3rd. She is the first woman appointed in this role, since the Collaboration foundation in the late 1980s.

It is with great sorrow that we announce the passing of Alain Brillet, French physicist, who has been one of the founding fathers of gravitational interferometry and Virgo, along with Adalberto Giazotto, who left us in 2017.

We pay tribute to Andrzej Trautman, one of the pioneers of gravitational wave theory and a leading figure in mathematical relativity, who passed away at the age of 93.

🇵🇱 This week the Embassy of the Republic of Poland in Rome hosted the Gravitational Waves and Detection Technologies - PAS Rome meeting 2026, jointly organized by the Polish Academy of Sciences, the University of Perugia and INFN Perugia, and supported by CAOS and EGO.

We’re happy to be hosting at EGO this week a group of @cern.bsky.social engineers working on @einsteintelescope.bsky.social, the future third generation gravitational wave detector, within the collaboration with the Einstein Telescope Organization (ETO).

Last week over 400 scientists of the @ligo.org - Virgo - KAGRA Collaboration met in Pisa, Italy for the LVK Meeting, the biannual gathering of the global community studying gravitational waves 🌟🌍

📢 The international network of gravitational wave detectors LIGO-Virgo-KAGRA (LVK) announces the publication of an updated catalogue of all gravitational events observed up to January 2024, called Gravitational-Wave Transient Catalogue-4.0 (GWTC-4).

From March 9th to March 13th, Pisa will be home to the global gravitational waves community! EGO and Virgo will host the @ligo.org - Virgo - KAGRA Collaboration Meeting, the biannual meeting of the gravitational wave community, for the first time in Italy after more than a decade.

🧐 How many theories can be verified with a single #GravitationalWave signal? At least three, if this signal is GW250114, observed by the @ligo.org - Virgo - KAGRA Collaboration in January 2025. #10yearsofGravitationalWaves #GW10

🍂 What if a black hole born from the merger of two black holes merged with another black hole? We may find out thanks to gravitational waves, such as those observed by the @ligo.org - Virgo - KAGRA Collaboration in autumn 2024. Let's learn about these signals!

Yesterday at the Planetarium of Rome, on the tenth anniversary of the announcement of the discovery of gravitational waves, the film for planetariums "Einstein Telescope, listening to the universe beyond the stars" was screened for the first time.

Yesterday at Palazzo Farnese in Rome, we celebrated the tenth anniversary of the announcement of the discovery of gravitational waves with an event organised by the Italian Ministry for University and Research, the Italian National Institute for Nuclear Physics (INFN), @cnrs.fr and EGO (more below)

Today is the International Day of Women and Girls in Science ♀️ Change is possible and is already happening, but there is still a lot to do, here’s some data to help us understand!

Not all black holes observed in 10 years of #GravitationalWaves were predicted by theoretical models. This is the case for two signals observed by the LIGO-Virgo-KAGRA Collaboration in 2019 and 2023. Let's find out more!

✨In 10 years of #GravitationalWaves, the LIGO, Virgo and KAGRA interferometers have observed some enigmatic, unexpected signals. One of the most interesting of these was observed in August 2019 and involves a black hole and a mysterious object. Let's find out more!

Since its publication, over one hundred years ago, Albert Einstein’s theory of general relativity has revolutionized physics and our knowledge of the universe, and testing its accuracy in different scenarios has been a fundamental mission of experimental physics.

✨Did you know that #GravitationalWaves have also allowed us to observe mergers between #BlackHoles and #NeutronStars?

Gravitational wave science continues to inspire artists, and especially musicians, all over the world 🎶 “The Symphony of the universe” is a project by artist Ana Schurmann and scientists of the Virgo Brasil Group Cássius Anderson Miquele de Melo and Regiley Pimenta Ramos de Oliveira

✨ Gravitational waves have allowed us to detect extreme astrophysical events. Among these, #GW170817, the collision of two neutron stars observed for the first time both through gravitational waves and electromagnetic radiation, has opened a new window onto the Universe.

Congratulations to John Clarke, Michel H. Devoret and John M. Martinis, awardees of the 2025 Nobel Prize in Physics “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit”!

Ondas gravitacionales, fal grawitacyjnych, ondes gravitationnelles, onde gravitazionali, everyone was talking about gravitational waves on European Researcher’s Night 🌊

On September 14th 2015, the @LIGO - Virgo Collaboration finally detected gravitational waves, ripples in the "fabric" of space-time produced by events such as the merger of two black holes. Today we are happy to celebrate the 10th anniversary of this sensational discovery!

Exactly 10 years ago, the signal of a gravitational wave from the merger of two black holes arrived on Earth. It was not a special signal, but one like many that had always reached our planet. On that day, however, for the first time humankind was ready to listen to it. (1/7)

Ten years after the first gravitational wave, there is a new breakthrough: Hawking was right www.nikhef.nl/en/news/ten-... @ligo.org @egovirgo.bsky.social

Just a few days before the 10th anniversary of gravitational wave detection, the @ligo.org - Virgo - KAGRA Collaboration is happy to announce a new major detection 📣 The signal, named GW250114, has provided us with the best observational proof to date of Stephen Hawking's black hole area theorem 🕳️🕳

It is with great sadness that we learn of the passing of Rainer Weiss, one of the fathers of gravitational wave research, founder of @ligo.org and Nobel Prize laureate in physics for the detection of gravitational waves in 2017. Photo credits: MIT/Bryce Vickmark
