Journalists are invited to join the National Science Foundation (NSF) as it brings together scientists from the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo collaborations, as well as representatives for some 70 observatories, Monday, Oct. 16, at 10 a.m. EDT at the National Press Club in Washington, D.C.

The gathering will begin with an overview of new findings from LIGO, Virgo and partners that span the globe, followed by details from telescopes that work with the LIGO and Virgo collaborations to study extreme events in the cosmos.

The first detection of gravitational waves, made Sept. 14, 2015 and announced Feb. 11, 2016, was a milestone in physics and astronomy; it confirmed a major prediction of Albert Einstein’s 1915 general theory of relativity, and marked the beginning of the new field of gravitational-wave astronomy. Since then, there have been three more confirmed detections, one of which (the most recently announced) was the first confirmed detection seen jointly by both the LIGO and Virgo detectors.

The published articles announcing LIGO’s first, second, and third confirmed detections have been cited more than 1,700 times total, according to Web of Science citation counts. A fourth paper on the three-detector observation was published Oct 6; a manuscript was made publicly available Sept. 27.

Journalists interested in attending should RSVP to as soon as possible, and by 12 p.m. EDT Friday, Oct. 13 at the latest, to guarantee a response.

Due to seating constraints and security at the venue, journalists interested in attending should RSVP to as soon as possible, and by 12 p.m. EDT Friday, Oct. 13, at the latest, to guarantee a response. We will try to accept RSVPs after that point, but cannot guarantee access. A mult box will be available for broadcast media, and the Press Club is equipped with wireless access.

Reporters interested in receiving embargoed information related to the research being presented can contact the media representative listed below or email; in doing so, please confirm that you and your outlet’s editors honor embargoes. We will then share embargoed material with you Friday, Oct. 13.

To RSVP or request embargoed material, please email Please refer other questions to the public information officers listed in the "Media Contacts" section below. 


For press not based in the Washington, D.C., area, this event will be simulcast live online, and we will try to answer some questions submitted remotely. For details about how to participate remotely, please contact Aya Collins at NSF. 


LIGO is funded by NSF, and operated by Caltech and MIT, which conceived of LIGO and led the Initial and Advanced LIGO projects. Financial support for the Advanced LIGO project was led by NSF with Germany (Max Planck Society), the U.K. (Science and Technology Facilities Council) and Australia (Australian Research Council) making significant commitments and contributions to the project. More than 1,200 scientists from around the world participate in the effort through the LIGO Scientific Collaboration, which includes the GEO Collaboration. Additional partners are listed at

The Virgo collaboration consists of more than 280 physicists and engineers belonging to 20 different European research groups: six from Centre National de la Recherche Scientifique (CNRS) in France; eight from the Istituto Nazionale di Fisica Nucleare (INFN) in Italy; two in the Netherlands with Nikhef; the MTA Wigner RCP in Hungary; the POLGRAW group in Poland; Spain with the University of Valencia; and the European Gravitational Observatory, EGO, the laboratory hosting the Virgo detector near Pisa in Italy, funded by CNRS, INFN, and Nikhef.
