For the first time three gravitational wave detectors have recorded the same event. The detection was made by both LIGO and Advanced Virgo (which has just recently begun collecting data for the first time). From the news release:
The LIGO Scientific Collaboration and the Virgo collaboration report the first joint detection of gravitational waves with both the LIGO and Virgo detectors. This is the fourth announced detection of a binary black hole system and the first significant gravitational-wave signal recorded by the Virgo detector, and highlights the scientific potential of a three-detector network of gravitational-wave detectors.
The three-detector observation was made on August 14, 2017 at 10:30:43 UTC. The two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, and funded by the National Science Foundation (NSF), and the Virgo detector, located near Pisa, Italy, detected a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes.
A paper about the event, known as GW170814, has been accepted for publication in the journal Physical Review Letters.

Did not this happen more than a MONTH ago? I had my gravity surfing board all waxed up and ready to go. So, time dilation, or SoylentNews slipping away, avoiding aristarchus submissions, causing black holes to collide and, "Do you have any idea the powers you are meddling with? Eds? Well, Do ya! Punks?"

One dimensional thinking detected, indirectly of course

But, still, not an August occurance? Oh! First Three detector event! As opposed to the only two detector event, which was not nearly so hyped by the mainstream left-wing pro-gravity media? Is that what you are saying??? OK, my bad.

A man with no subtly or sense of humor I make a black hole joke and you have to go off on some sort of political left/right thing, you know none of that matters to one dimensional objects right?

Wait, you think black holes are one dimensional objects? Wow, not until you get past the event horizon, my chipo! And even then, you are "spagettified", definitely not a one dimensional process. Maybe only two, at the extreme end.
Now, if we are to make political analogies, let us be very clear that these are only analogies, and are not meant to be taken literally. But do you not think that a conservative mindset is something like a black hole? No matter what the information is, it is sucked in and extinguished in darkness. Rather like Fox News! No matter what the information is. This is why Hawkings hypothesis that black holes can emit information is so disturbing. Could it be that conservatives actually have something to say, after being sucked into a singularity of infinite liberality, where we are all one, and everyone has health care and black lives matter?

Clue - Sept 27 was a day back, not a month back (and greetings to my readers on the Pacific for whom it's still the 27th)
Sure, they dropped hints that they had some interesting looking candidates at the start of this month, but, in their own words, "it will require time to establish the level of confidence needed to bring any results to the scientific community and the greater public. We will let you know as soon we have information ready to share."
Do you want press departments pushing upon the world half-baked false positives, or do you want the scientists to be doing science correctly?

I want eds that are not pressured by alt-right leaning birds of carrion. That is all I want. As for this, point taken. Only recently announced, for all three. But the one in Pisa, I suspect, was leaning, slightly.l

"more than a MONTH ago"
Probably, yes.
"located about 1.8 billion light-years away."
I don't know how fast gravity waves travel, but it seems that it actually happened at least a billion years ago. So, yes, old news for sure.
