Tiny particles forged in the heart of the sun have been detected for the first time, offering scientists a glimpse into the nuclear fusion core of our closest star.
The subatomic particles, called neutrinos, are hallmarks of the dominant fusion process insidethe sun. Created in the first step of a reaction sequence responsible for the majority of the sun’s fusion, the particles have long eluded detection. Now, an international collaboration of more than 100 scientists working with the Borexino detector in Italy has made the first measurements of these elusive particles.
The new findings “allow us to look at the majority of the fusion reactions in the sun’s core in real time, as they happen, minus an eight-minute delay for travel to Earth,” Andrea Pocar, of the University of Massachusetts and part of the Borexino team, told Space.com by email. ”The measurement allows us to strongly confirm the model of the sun, and to take a ‘neutrino photograph’.”
