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. :)
- cubefox 4y agoI think that the unusual thing was that they identified extragalactic neutrinos.
- friendlyasparag 4y agoIceCube also likes to name their events after Sesame Street characters, so you’d get things like Bert and Ernie events. Not sure if they still do since you eventually run out of characters.
- ouid 4y agoits possible you havent been keeping up with sesame street, because no they won't.
- sonofaragorn 4y agoThe energy of the IceCube neutrinos is 2 to 4 orders of magnitude higher than the ones detected by this experiment. But this is still cool because it's the highest energy neutrinos detected from man-made sources.

- hguant 4y ago> IceCube Neutrino Observatory (funny name lol) It's also an incredibly descriptive and literal name - the observatory is a cubic kilometer of photosensitive detectors frozen in ice at the south pole. When a neutrino interacts with the ice, it produces cherenkov radiation, which can be detected and sent up the chain to a server to classify what was actually detected.
- EschatonCometh 4y agoYeah, wasn't it Sheldon Cooper who discovered that? - JK
