We ve spotted a neutrino blasted out by a black hole shredding a star

DESY, Science Communication Lab In a distant galaxy, a supermassive black hole ripped a star to bits, sending out an enormous blast of energy. For the first time, researchers have observed a neutrino that probably came from this type of cataclysm, which is called a tidal disruption event or TDE. Neutrinos are tiny particles that rarely interact with other matter, making them extremely difficult to detect. On 1 October 2019, the IceCube Neutrino Observatory in Antarctica spotted a neutrino with relatively high energy that appeared to come from beyond our galaxy. Advertisement Meanwhile, Robert Stein at the German Electron Synchrotron (DESY) and his colleagues were using the Zwicky Transient Facility in California to watch a star that had got too close to a supermassive black hole. The extreme gravity of the black hole shredded the star, creating a TDE that lasted for months. The TDE and the IceCube neutrino came from the same location in the sky, indicating that the ripped-up sta

Rare cosmic neutrino traced to star-swallowing black hole

Share When a supermassive black hole tears a star apart (imagined here), it produces copious light and maybe neutrinos, too. DESY/Science Communication Lab Rare cosmic neutrino traced to star-swallowing black hole Feb. 22, 2021 , 11:00 AM Neutrinos are everywhere trillions of the virtually massless particles pass through your body every second but they’re notoriously hard to pin down, especially the rare high-energy ones from deep space. Only about a dozen of these cosmic neutrinos are detected annually, and scientists had connected only one to its source. Now, IceCube, the kilometer-wide neutrino detector nestled deep beneath the South Pole, has traced another one back to its far-flung birthplace: a supermassive black hole tearing a star to pieces in a galaxy 750 million light-years away.

Bad Astronomy, Quasar 3C273 was most distant astronomical object in 1962

Foreword: One of the fun things about having written thousands (!!) of articles about astronomy over the past decade or two is going through old posts looking for relevant info. If I’m writing about a black hole, say, then it helps to link to older articles that have background info, saving me the trouble of writing it again. Every now and again I’ll be writing about some particular object and then hit the archives to see what I’ve said about it before. It doesn’t happen often, but sometimes I’ll find… nothing. Meaning, I haven’t written about this particular object before. That’s fine; I can’t write about everything, but what’s weird is when it’s about some famous or particularly iconic astronomical object. A few years ago, for example, I was looking for stuff I had written about Proxima Centauri, the closest star to the Sun, and discovered I had never written an article devoted to it! That was weird, and now happily fixed (many times over).
