There you go folks:Posted by StandingWave (here)
I dont know if this has been announced anywhere else in the Avalon forum yet, so here goes - big announcement from the European Southern Observatory for Monday 16 October 2017:
ESO Public AnnouncementESO will hold a press conference on Monday 16 October 2017 at 16:00 CEST, at its Headquarters in Garching, Germany, to present groundbreaking observations of an astronomical phenomenon that has never been witnessed before.
Since this result may have very wide interest we are also inviting members of the public to view the press conference online at www.eso.org/live starting at 16:00 CEST.
We cannot take questions from the public during the press conference, but anyone who wishes to interact with the people involved in the discovery can attend a Reddit Ask Science AMA session on https://redd.it/76ne3p , starting 18:30 CEST. Details will be provided from Monday 16 October 2017 16:00 CEST on ESO’s social media channels.
An ESO press release will be published at the start of the conference on ESO’s website at eso.org. Translations of the press release will be available in several languages.

Chandra X-Ray Observatory
GW170817
Published 16th October 2017
Astronomers have used NASA's Chandra X-ray Observatory to make the first X-ray detection of a gravitational wave source. Chandra was one of multiple observatories to detect the aftermath of this gravitational wave event, the first to produce an electromagnetic signal of any type. This discovery represents the beginning of a new era in astrophysics.
The gravitational wave source, GW170817, was detected with the advanced Laser Interferometer Gravitational-Wave Observatory, or LIGO, at 8:41am EDT on Thursday August 17, 2017. Two seconds later NASA's Fermi Gamma-ray Burst Monitor detected a weak pulse of gamma rays. Later that morning, LIGO scientists announced that GW170817 had the characteristics of a merger of two neutron stars.
During the evening of August 17, multiple teams of astronomers using ground-based telescopes reported a detection of a new source of optical and infrared light in the galaxy NGC 4993, a galaxy located about 130 million light years from Earth.
Over the following two weeks, Chandra observed NGC 4993 and the source GW170817 four separate times. In the first observation on August 19th, no X-rays were detected at the location of GW170817. This observation was obtained remarkably quickly, only 2.3 days after the gravitational source was detected.
On August 26, Chandra observed GW170817 again and this time, X-rays were seen for the first time. This new X-ray source was located at the exact position of the optical and infrared source.
All of these pieces of information indicate that this event was produced by the merger of two neutron stars, which, in turn, set off a gamma-ray burst that produced a jet pointing away from Earth. The combination of gravitational wave signals with light detected by various telescopes including Chandra represents a new era in astrophysics.
From ESO:
The signal measured by LIGO and Virgo from the neutron star merger GW170817 is compared here to previously detected binary black hole mergers. All signals are shown starting at 30 Hertz, and the progression of GW170817 is shown in real time, accompanied by its conversion to audio heard at the end of the movie. GW170817 was observable for more than 30 times longer than any previous gravitational wave signal.
