Unfortunately, KM3NeT led to the discovery of the Pauli anglerfish, which emits Cherenkov radiation to prey on neutrino researchers.

KM3NeT [Explained]

Transcript Under the Cut

[Ponytail is presenting to Cueball and Megan on a drop down screen.] [On the screen is a side view of a deep-water telescope, attached to the bedrock, floating in the ocean. It looks like four series of circles stringed together from the ground.] Ponytail: The KM3NeT deep-water telescope detects the flashes of Cherenkov light from neutrino interactions. Cueball: How do you know you aren't just seeing bioluminescent fish? Ponytail: Cherenkov radiation is only emitted when things exceed the local speed of light, so it can't be produced by under-c life.

Ghost Particle from the Cosmos: Scientists May Have Solved the Mystery of the Most Energetic Neutrino Ever Detected

More than two miles below the surface of the Mediterranean Sea off the coast of Sicily, an extraordinary observatory called KM3NeT sits in total darkness and it has been quietly rewriting the record books. In February 2023, it recorded the most energetic particle of its kind ever observed: a cosmic neutrino nicknamed KM3-230213A, carrying an estimated energy of 220 PeV (220 quadrillion electron…

🌊⚛️ Beneath 3,450 metres of Mediterranean water, KM3NeT registered the most energetic neutrino ever observed: 220 PeV. Ten times more than any predecessor. It could be the first cosmogenic neutrino in history, or it could openly challenge IceCube. I walk you through what the collaboration actually found, what the Nature paper says and why the community has been debating this event for a year.

KM3-230213A: the neutrino that broke the scale

🌊⚛️ Bajo 3.450 metros de agua mediterránea, KM3NeT registró el neutrino más energético jamás observado: 220 PeV. Diez veces más que cualquier predecesor. Podría ser el primer neutrino cosmogénico de la historia, o podría desafiar abiertamente a IceCube. Le cuento qué encontró exactamente la colaboración, qué dice el paper de Nature y por qué la comunidad lleva un año debatiendo este evento.

⚡🔭🌌 The highest-energy neutrino ever detected — recorded in 2023 deep in the Mediterranean by the KM3NeT/ARCA detector — may have been produced by a population of blazars, the most extreme particle accelerators in the universe. A new study in JCAP presents the most physically consistent model to date for explaining this unprecedented event, which surpasses all prior detections by more than an order of magnitude. An open question that multimessenger astrophysics is finally beginning to answer. 🧲💫🕳️

KM3NeT detecta el neutrino de mayor energía jamás registrado: los blazares como posible origen

En febrero de 2023, el detector de neutrinos KM3NeT/ARCA registró en las profundidades del Mediterráneo un evento que no tenía precedente en la astrofísica de partículas. Un neutrino cósmico cruzó el detector con una energía de aproximadamente 220 petaelectronvoltios (PeV), superando en más de un orden de magnitud todo lo observado anteriormente. El evento, catalogado como KM3-230213A, lleva tres…
