Every second, almost 100 trillion neutrinos pass through our body.
Scientists working at the IceCube Observatory have detected seven rarely seen “ghost particle” candidates traversing Earth. The observatory buried deep in the ice of Antarctica’s south pole witnessed the phenomenon after 9.7 years. These ghost particles, also known as astrophysical tau neutrinos, function as messengers between powerful celestial events and humans. Neutrinos have zero mass and no charge. They can travel through space at a speed similar to that of light. Due to their parameters, neutrinos barely interact with anything they encounter.
Every second, almost 100 trillion neutrinos pass through our body. But his lightning speed makes it impossible for us to notice, justifying the reason for his ghostly nickname. In fact, even if you were a human-sized neutrino detector, it would take about a century for the particle to forge any kind of interaction with your body.
Astrophysical neutrinos are high-energy neutrinos that come from cosmic sources near the edge of the Milky Way, which were first detected by the Observatory in 2013. Now, with the detection of astrophysical tau neutrinos, astronomers have found a new variation of the cosmic galaxy. Delivery courier.
In a statement, Doug Cowen, co-director of the project, said: “The detection of seven candidate tau neutrino events in the data, combined with the very low amount of background expected, allows us to say that it is very unlikely that funds are colluding. to produce seven impostors of tau neutrinos.”
“The discovery of astrophysical tau neutrinos also provides strong confirmation of IceCube’s earlier discovery of diffuse neutrinos. astrophysicist neutrino flux,” added Doug Cowen, who is also a physics professor at Penn State University.
Digital optical modules, also known as DOMs, are strings of golden balloons buried in ice that the IceCube Observatory uses to identify neutrinos as they travel through the Earth. 5,160 DOM are buried deep under the Antarctic ice, waiting to produce charged particles when neutrinos come into contact with ice molecules. As these charged particles pass through the ice, they release blue light, which is detected by the DOMs.
Only three chains of DOM detectors were used in the current investigation. This discovery will not only help expand the sample of tau neutrinos, but will also allow scientists to embark on the first three-generation investigation of neutrino oscillations.
