‘Ultrahigh Energy’ Neutrino Found With a Telescope Under the Sea
The team announced its “ultrahigh energy” neutrino on Wednesday, in a paper published in the journal Nature. The finding brings physicists and astronomers one step closer to understanding just what, exactly, is out there thrusting particles to such unfathomable speeds.
A neutrino telescope spots the signs of something cataclysmic
A neutrino telescope, therefore, is a giant exercise in statistics. Observe lots of atoms for a long time and sooner or later you will see a collision. Detectors like Super Kamiokande, in Japan, or ICE Cube,
A deep-sea neutrino telescope spots the most energetic ghost particle yet
A neutrino detector submerged in the Mediterranean Sea has sniffed out the most energetic ghost particle yet, scientists reported Wednesday. The newly detected neutrino is around 30 times more active than the previous recordholder.
How our team spotted the most energetic neutrino detected to date
Recent research on lightweight particles called neutrinos might have passed you by—much like the more than 10 trillion neutrinos passing through your body each second. Now, our new paper—with 21 countries,
High-energy cosmic neutrino detected under Mediterranean Sea
Using an observatory under construction deep beneath the Mediterranean Sea near Sicily, scientists have detected a ghostly subatomic particle called a neutrino boasting record-breaking energy in another important step toward understanding some of the universe's most cataclysmic events.
Record-breaking neutrino is most energetic ever detected
Although still under construction, the sea-floor KM3NeT detector spotted a neutrino 20 times more powerful than any previously detected.
First ultra-high-energy neutrino detected in deep-sea telescope
An extraordinary event consistent with a neutrino with an estimated energy of about 220 PeV (220 x 1015 electron volts or 220 million billion electron volts), was detected on February 13, 2023, by the ARCA detector of the kilometer cubic neutrino telescope (KM3NeT) in the deep sea.
Most energetic neutrino yet seen smashes through seafloor detector
For context, the most powerful particle accelerator on Earth, the Large Hadron Collider, accelerates protons to an energy of 7 Tera-electronVolts (TeV). The neutrino that was detected had an energy of at least 60 Peta-electronVolts, possibly hitting 230 PeV. That also blew away the previous records, which were in the neighborhood of 10 PeV.
