Scientists help discover the highest-energy light coming from the sun

New research details the discovery of the highest-energy light ever
observed from the sun.
Up to 10 TeV gamama radiation
A 10-TeV _gamma_ from the Sun?
That reporter must specialize on climate issues.

Why wouldn\'t a 10 Tev gamma reach the earth\'s surface?
They are conjecturing a lot from a few flashes in a water
tank.

Getting that sort of energy in a proton is a possibility for cosmological
sources, at least. There have been reports of cosmic ray showers whose
total energy is on the order of 10**20 eV, and cosmological mechanisms have
been proposed to explain them.
AFAIK all involve extreme magnetic fields and large distances. The Sun is
too small, and its fields too weak and chaotic to be an effective
accelerator, so solar protons top out at nuclear-type energies (10 MeV for
a juicy one).
But I know of no mechanism whatsoever capable of producing TeV _gammas_.
You canât accelerate a gamma. Gammas come from annihilations, which top out
around 1 GeV, and from inelastic scattering events, which are much lower.
