Scientists Confirm Long-Held Theory About Source of Sunshine

It is always good to confirm a long-standing understanding of anything. This is such a case done at Gran Sasso National Laboratory near L'Aquila, Italy. By observing the low-energy neutrinos from the sun, they have verified the type of nuclear reaction going on inside the sun that generates all of the energy.

"Our observations essentially confirm that we understand how the sun shines," said Frank Calaprice, a professor of physics and principal investigator of the Princeton team. "Physicists have had theories regarding the nuclear reactions within the sun for years, but direct observations have remained elusive. Now we understand these reactions much better."
