After the great success of last year, EGO and the PICO Project , funded by the European Union, are happy to bring back the remote tours to the Virgo interferometer ✨ tinyurl.com/Virgo-virtua...

EGO and Virgo have been undergoing a reorganization to tackle the new challenges of gravitational and multimessenger astronomy. As part of this effort they are proud to announce the creation of the VirgoLab ▶️https://www.ego-gw.it/blog/2025/12/17/ego-and-virgo-reorganize-and-create-the-virgolab/

The ENGRAVE scientific collaboration has been awarded the Into Change prize, in its first edition, by the Danish Ministry of Higher Education and Science. The prize is dedicated to European research groups that have conducted exceptional and innovative studies at the highest international level 🏅

Today marks the end of the fourth observing run of the @LIGO - Virgo - @KAGRA_PR gravitational wave detection network 🎆 It was the longest and richest run ever: 585 days and 250+ significant candidate signals, a huge increase from the 90 events of the three past runs combined🤯

@ligo.org, Virgo and KAGRA have observed 'second generation' black holes for the first time! 🕳️🕳️ In a new paper published today in The Astrophysical Journal Letters, the International Collaboration announced the observation of two very special gravitational signals

This morning the five year renewal of the EGO consortium agreement was signed during a meeting of the EGO Council, formed by representatives of the funding agencies ✍️

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

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 🔭🧪⚛️☄️ #GWTC4

Today we celebrate the eight-year anniversary of a discovery that changed astronomy forever: on this day eight years ago @ligo.org and Virgo detected their first ever neutron star merger, GW170817 💥

Exactly eight years ago Virgo was detecting its first ever gravitational wave signal, the first signal ever caught by three gravitational wave detectors together: the two @ligo.org detectors and Virgo 🤝

We are deeply saddened to hear of the passing of Bob Wilson, world-renowned theater stage director and playwright that we had the honour and pleasure to welcome at EGO and Virgo in 2022, invited by Stavros Katsanevas.

"Merger of two massive black holes is one for the record books" @jenlucpiquant.bsky.social reports on our LIGO @egovirgo.bsky.social KAGRA discovery of #GW231123 arstechnica.com/science/2025... 🔭🧪⚛️

The @ligo.org - Virgo - KAGRA Collaboration is happy to announce the detection of the merger of the most massive black holes ever observed with gravitational waves 🕳️🕳️

In this morning’s plenary at #GR24Amaldi16, Amanda Farah introduces the newest (and most massive and likely most rapidly spinning) @ligo.org - @egovirgo.bsky.social - KAGRA event, #GW231123! Read more about this exceptional event in the discovery paper: arxiv.org/abs/2507.08219

🎉 Happy 50th anniversary to @nikhef.bsky.social! From all of us at @cnrs-in2p3.bsky.social, thank you for being such great partners in science. Here's to many more years of fruitful collaboration, from @egovirgo.bsky.social and the LHC to @km3net.bsky.social and beyond! 🌍 #nikhef50

Comicon Naples was out of this world 🚀 Thousands of people came to our stand and over 800 had the immersive experience of the Big Bang Machine! Thanks to everyone for the enthusiasm, and stay tuned for the next events 🚛

Today in Foligno during the Festa di Scienza e Filosofia the @ligo-sci-collab.bsky.social - Virgo - KAGRA Collaboration received an award, instituted by the Laboratory of Experimental Sciences of Foligno, in celebration of the tenth anniversary of the first detection of gravitational waves.

April Fools' Day! This post was an April Fools joke, thank you for having fun with us 🥳 Although we didn't install 300 balloons on Virgo's arms this year we will indeed celebrate the 10th anniversary of the first detection, with many events. Keep following us to find out 😉

To celebrate the tenth anniversary of the first detection of a gravitational wave signal, on September 14th 2015, the largest installation of flying balloons ever made was inaugurated today at the European Gravitational Observatory in Cascina 🎈🎈🎈

Earlier this month at Sapienza University in Rome a group of PhD students of the INFN Virgo Rome Group, coordinated by Francesca Attadio and Sarah Ferraiuolo, organized a day-long gravitational wave masterclass dedicated to high school female students.

🍾The LIGO - Virgo - KAGRA Collaboration has announced the detection of the 200th candidate gravitational wave signal in this fourth observation period O4!

The European Gravitational Observatory (EGO) consortium is growing, now counting five institutions from four countries! With the signing of a formal agreement during today’s Council meeting the Belgian Research Foundations @fwovlaanderen.bsky.social and FNRS have become members of EGO!

This week we had the pleasure of welcoming Alice Paltrinieri, the artist we are hosting in residence at Virgo this year in collaboration with Spazio Taverna 🖌️

⏳Last days to sign up for Virgo's remote tour, free and in English! Don't miss the chance to virtually explore the largest gravitational wave detector in Europe! 🌍✨ Register here: forms.gle/yBXqfGkQsKnz...

Today the Wikipedia page regarding Virgo is featured on the main page of @wikipedia.org, a recognition of its outstanding quality by the community of volunteers maintaining the world’s most famous online encyclopedia! (1/3)

The LIGO - Virgo - KAGRA (LVK) collaboration recently conducted a new search for extremely faint continuous gravitational waves from isolated neutron stars, specifically 45 known pulsars, using data from the first part of the fourth observing run (O4a). (1/7)

Exactly nine years ago, on the 11th of February 2016, the LIGO - Virgo Collaboration announced the direct observation of gravitational waves to the world (1/4)

Today is International Day of Women and Girls in Science, working every day to make science more…let’s hear it from some of the women of the Virgo Collaboration! 👩‍🔬

As the third portion of the fourth observing run, O4c, is starting the LIGO - Virgo - KAGRA Collaboration is announcing an upcoming break from observing to dedicate some time to maintenance and commissioning work, and therefore an extension of the O4 run, that was previously planned to end in June.

Today is the International Day of Education! 🎓 📚 In 2024 we organised 137 guided tours of Virgo, welcoming almost 10,000 visitors, including thousands of students from 76 schools of all levels, in 15 different regions of Italy and 10 countries around the world 🗺️

EGO and the EU-funded PICO Project are thrilled to offer three exclusive remote visits of the Virgo interferometer mainly dedicated to high schools worldwide and conducted in English🎓✨ 📅 Don’t miss this opportunity!
