Astronomy Picture of the Day: Neutrinos in the Sun
- This image of the sun was made with neutrinos, which are tiny, almost-massless particles that move at nearly the speed of light. Neutrinos are created in nuclear reactions, and were first detected near a nuclear reactor.
The nuclear reactions that power the sun produce lots of neutrinos. In fact, billions of them per second are passing through your hand right now.
For more about the image, see Astronomy Picture of the Day: Neutrinos in the Sun. To learn how the measurement of solar neutrinos led to a change in fundamental physics, check out this PBS webpage.
