This is an awesome update. It was only in 2018 that a high energy neutrino was detected by the IceCube Neutrino Observatory (funny name lol) that was traced back to its source, a blazar. This was a active galaxy with a supermassive black hole at its center. That was the first time ever that scientists had identified the source of a high energy neutrino, and now scientists generated a whole new avenue of research in astrophysics with this. :)
