Solar Neutrino Astronomy

We take a break from the bugs, all kind of bugs, and concentrate on the sun. This is the sun again.

The neutrino flux variations on the sun match most exactly the rotation rates of the areas shown in red on this colorful cross-sectional map of the solar interior rotation. The neutrinos are still a mystery to us, but we keep trying to understand. The next big experiment is the Ice Cube in Antarctica.
