How Neutrinos Switch Flavors While Traveling Through the Sun ⚡ экспресс
Solar neutrinos can change their type on their way to Earth — it's like water turning into vapor depending on the air density. Scientists have figured out a way to clean the data from noise to finally see this effect in the JUNO detector. Will we be able to peer into the heart of the Sun differently in 10 years?
Our Sun emits streams of neutrinos — particles that barely interact with matter. Passing through the dense solar material, they change their type — scientists call this 'flavor.' It's like a voice that changes as it moves through a crowd: the thicker the crowd, the more it gets distorted.
This effect was long predicted by theory, but hearing it directly was drowned out by the roar of cosmic noise — as if you were trying to make out a whisper during a rock concert. The JUNO detector in China uses a method that works like a smart noise-canceling system: it filters out the racket and, over ten years, will gather enough data to pinpoint how neutrino energy affects their spectrum of transformations.
Unexpected fact: neutrinos born in the Sun's core almost completely change their type before even emerging. What Earth-based detectors pick up are already the 'foreign voices' of these particles. The discovery will strengthen the Standard Model of physics and support future giant experiments.
