Data from gamma-ray telescopes and our gravitational-wave detectors showing the coincidence of GW170817 and GRB 170817A

It has been, somewhat unbelievably, just over seven years since we detected #GW170817, which was notable for just how many firsts it represented in astronomy:
+ First observed merger of two neutron stars
+ First observation of #GravitationalWaves and light from the same event
+ First confirmed kilonova from a neutron star collision.
You'll find lots of coverage in the fediverse from @LIGO, but I'll leave you with this infographic I made, and my colleague translated into Glasgow dialect...

GW170817: binary neutron star merger
A LIGO Virgo gravitational wave detection with associated electromagnetic events observed by over 70 observatories
Distance: 130 million light years
Discovered: 17 August 2017

#GW170817 is the #GravitationalWave with the closest source. It is one of our loudest detections

Binary neutron stars are lower mass than black hole binaries, so their chirps are much longer

#GW170817's source was identified as in galaxy NGC 4993. It was observed using telescopes for all parts of the electromagnetic spectrum, making it one of the most studied astronomical events ever! It's afterglow was still visible years after the merger

#Astrodon

Localization of GW170817 and identification of the kilonova 10.9 hours after the merger

Combining data from LIGO Livingston, LIGO Hanford and Virgo, we localized #GW170817's source on the sky. Having 3 detectors is crucial for this

Using this localization, teams of astronomers from around the world were able to successfully hunt for GW170817's kilonova

Happy birthday to #GW170817 our first binary neutron star detection, and the first #GravitationalWave with electromagnetic counterparts!

The gamma-ray burst following the merger was spotted by the Fermi and Integral telescopes and later many other telescopes

#Astrodon

Artistic representation of the merger of two neutron stars. The neutron stars emit gravitational waves, inspiralling together. After they merge, they emit large jets (a gamma-ray burst) and a fireball of ejected material (a kilnova)

HAPPY BIRTHDAY GW170817!

I didn't have time to make new art, and other accounts are already doing a great job of posting about the science-y parts, so instead I'll post my BNS-inspired art 😊

Happy Birthday, GW170817! Six years ago today, @LIGO and Virgo observed gravitational waves from merging neutron stars for the first time, and many other telescopes observed the electromagnetic radiation produced by the event.
