as the result of thermonuclear reactions in the core of the sun and

he announcement on June 18, 2001 of the first physics results from
the Sudbury Neutrino Observatory (SNO) in which it was shown that
solar neutrinos have a mass and can "oscillate" or change
their identity en route from the sun to the Earth made headlines in
newspapers all over the globe. The discovery was even the subject
of an entire broadcast of the popular ABC news show Nightline. |
