Related: About this forumScientists find neutrinos from star fusion for the first time
It could help understand dark matter and the universe.

Researchers have effectively confirmed one of the most important theories in star physics. NBC News reports that a team at the Italian National Institute for Nuclear Physics has detected neutrinos traced back to star fusion for the first time. The scientists determined that the elusive particles passing through its Borexino detector stemmed from a carbon-nitrogen-oxygen (CNO) fusion process at the heart of the Sun.
This kind of behavior had been predicted in 1938, but hadnt been verified until now despite scientists detecting neutrinos in 1956. Borexinos design was crucial to overcoming that hurdle its onion-like construction and ongoing refinements make it both ultra-sensitive and resistant to unwanted cosmic radiation.
Its a somewhat surprising discovery, too. CNO fusion is much more common in larger, hotter stars. A smaller celestial body like the Sun only produces 1 percent of its energy through that process. This not only confirms that CNO is a driving force behind bigger stars, but the universe at large.
That, in turn, might help explain some dark matter, where neutrinos could play a significant role. Scientist Orebi Gann, who wasnt involved in these findings, also told NBC that an asymmetry between neutrinos and their relevant antiparticles might explain why there isnt much known antimatter in the universe. To put it another way, the findings could help answer some of the most basic questions about the cosmos.

Even the description sounds like science fiction. Made inside the sun. Detected under a mountain.

+1. Really cool. Major particle physics discovery not from the Hydron Collider.
