Wow! 🤩 Look at this very nice brand-new representation of our #neutrino detector. It shows real #KM3NeT #data from the Mediterranean #deepsea in a huge physical event display in the #hallway of the #Nikhef institute in Amsterdam, The Netherlands
The ladder gives an impression of the height of display. -
Ever wondered how KM3NeT’s #OpticalModules are built? It’s an elaborate, multi-step process to create these pressure-resistant spheres packed with 31 photomultipliers, power & data electronics, and calibration tools like compasses and nanobeacons.
Last week, KM3NeT collaborators gathered at the newly inaugurated #CAPACITY lab in #Caserta for the 2nd Optical Modules Integration Workshop.

On International Women's Day we put the spotlights on our #KM3NeT colleagues Dr Jutta Schnabel, Dr Lizeth Morales-Gallegos, Prof. Dr Annarita Margiotta and Prof. Dr Katerina Tzamariudaki.

Retour en douceur sur la détection exceptionnelle d’un neutrino d’ultra-haute énergie
https://next.ink/170416/retour-en-douceur-sur-la-detection-exceptionnelle-dun-neutrino-dultra-haute-energie/Une coalition internationale annonce la détection d’un neutrino d’ultra-haute énergie grâce au télescope #KM3NeT installé au fond de la mer Méditerranée. […]
Ils sont très difficiles à détecter. La solution : faire en sorte que le neutrino interagisse pour se transformer en muon. Ce dernier se propage alors « dans l’eau plus vite que la lumière, émet un cône de lumière bleutée, la lumière Tcherenkov ».
Attendez, comment ça plus vite que la lumière ? Rien ne va plus vite que la lumière !? C’est vrai… mais cette affirmation est valable dans le vide.

Rekord-Neutrino mit dem #KM3NeT Teleskop entdeckt.
Warum Rekord?
Weil es eine Rekordenergie von etwa 220 Millionen Milliarden Elektronenvolt hatte https://www.telepolis.de/features/Rekord-Neutrino-entdeckt-Tiefsee-Teleskop-eroeffnet-neues-Fenster-ins-Universum-10280006.html. -- Na dann gute Nacht, Mastodon. -

The neutrino left its trail while the observatory, #ARCA, anchored deep in the Mediterranean Sea, was still under construction.
“We’ve never seen a #neutrino this energetic, & we have been looking for them for a few decades now,” Wissel said. “We’re trying to understand what the #universe is capable of & how it does it — & this one neutrino is exciting.”

#Neutrinos weigh almost nothing & have no charge. They are generated by #nuclear #fusion reactions inside the #sun. Trillions stream through our bodies constantly, without anyone noticing.
But they are also generated outside our #galaxy, & because they rarely interact w/matter, they travel in straight lines from their origins to us—like arrows that pinpoint exactly where they came from. That can help scientists searching the #universe for astrophysical phenomena. -
“It’s incredible, right?” #neutrino physicist Paschal Coyle, a member of the #KM3Net team that did the research, said. “There are these objects in the #universe that can accelerate particles to such extreme energies. How that’s done, we don’t completely understand yet. So every piece of information that gives us a clue of the processes involved in achieving such high #energy — this is one of the main goals of #astronomy.”

Just as astronomers use telescopes that observe the light from stars to explore & explain the universe, scientists have set up massive telescopes deep in water & ice to measure #neutrino. These cosmic messengers can travel undisturbed over vast distances, carrying information about mysterious high-#energy events that generate them.

An international team of scientists announced Wed the detection of an extraordinary, elusive #neutrino — a tiny, subatomic particle that flitted at close to the speed of light toward an undersea detector off the coast of Sicily carrying about 30k times the #energy generated by the largest particle accelerator on #earth.
The observation, unveiled in the journal #Nature, revealed the highest-energy neutrino ever detected.#KM3NeT #astrophysics #science #cool

Our detectors do not build themselves:
As a tribute to the many #technicians and #engineers in the #KM3NeT labs together working on the construction of the #ARCA and #ORCA detectors of our #neutrino telescope, here a sneak peek into the KM3NeT lab at @_nikhef.
