On this day, for #LPF10anniversary: following the successful separation from the launch vehicle, the mission operations team at ESOC undertook one of the most complex Launch and Early Operations Phases (LEOP) ever undertaken or an ESA mission. Watch it here 📽️ www.youtube.com/watch?v=maKX...

We completed our setup and used it to characterize the photodiodes (red arrow) to be used in the suspension. @LIGO Livingston

From LISA Pathfinder to LISA: Celebrating 10 years of LPF launch 🛰💛 "A fantastic mission. Everybody who worked with LPF felt in love with the mission." - Stefano Vitale, LPF PI

2015 was a good year for gravitational-wave astronomy 🔭🧪🛰️ #LPF10anniversary #GW10Years

It's been 10 years since our dear LISA Pathfinder (LPF) launched! For the ones who don't know much about it, here's a quick refresher about your favorite mission's precursor 🛰️💛 #LPF10anniversary #LISAMission

The 2025 winner of the LIGO Laboratory Award for Excellence in Detector Characterization & Calibration is Dr. Jane Glanzer in recognizition of critical and timely contributions to both calibration and detector characterization for the fourth observing run www.ligo.caltech.edu/WA/news/ligo...

Our recent low-significance candidate #S251112cm has caught some interest. A false alarm or a big discovery—we will keep investigating. Catch up in these two articles www.science.org/content/arti... by Adrian Cho www.iflscience.com/candidate-gr... by @drcarpineti.bsky.social 🔭🧪☄️⚛️

Sad but pleased to release today our homage to LIGO’s wonderful Rai Weiss, who passed away in September just shy of his 93rd birthday. It is Episode 10 of our 9-year @ligo.org YouTube video series. In our last interview, he insisted that @NSF “is the hero of LIGO.” 🧪 youtu.be/hsiyG6Y0t4M

Our fourth LIGO @egovirgo.bsky.social KAGRA observing run has now drawn to a close. We will be busy analysing data for a while to come—watch out for more discovery announcements. We will be back next year observing.docs.ligo.org/plan/

In half an hour!

In the latest edition of the #LIGOMagazine, Catalina Miritescu told us all about bringing #GravitationalWave noise hunting with @ligo.org[email protected] to the Romanian National Astronomy and Astrophysics Olympiad! Read all about it at (pdf, page 38): ligo.org/wp-content/u...

LIGO, Virgo and KAGRA constantly battle with quantum effects on their mirrors (objects weighing more than 40 kg!), such as quantum radiation pressure noise, that is, fluctuations of the laser field that causes the mirrors to jitter.

Our next webinar will introduce our latest #GWTC4 release and the associated data (papers arxiv.org/abs/2508.18080 and arxiv.org/abs/2508.18079) Tomorrow at 15:00 UTC, with the recording on YouTube after Free registration wisconsin-edu.zoom.us/webinar/regi... ☄️🔭

Congratulations to Patrick for being honored by the American Physical Society! Prof. Brady is a long-standing member of our collaboration and our former Spokersperson

🔭Our fourth observing run is due to end on November 18. However, we now expect to have a 6 month observing run in 2026–27 to begin in the late summer/early fall of 2026, with detectors participating as available observing.docs.ligo.org/plan/ ☄️🧪⚛️

A Halloween visitor!

We are pleased to announce our discovery of #GW241011 and #GW241110 Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger? ligo.org/science-summ... #O4IsHere 🔭🧪⚛️☄️

The Kerr solution is truly remarkable. A mathematical description of black holes with just two parameters—this would make black holes the simplest macroscopic objects in the Universe. And all our observations show that this does describe astrophysical black holes as far as we can tell 🔭⚛️🧪

Happy birthday GW150914! When you were detected I was still an undergrad looking to get into GWs for her PhD (it's important to my internal story of myself that I wanted to do this *before* the detection) It's hard to believe how far we've come since then. 🐡🧪🔭 #GW10Years

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)
