What in the universe has a temperature of around 1.9*10^11? (C or K, take
your pick.)
According to Wien's law, the peak emission wavelength of a blackbody at
temperature T is
lambda = 0.29 cm-K / T
So the peak wavelength of a blackbody at 1.9e11 is
lambda = 1.5e-12 cm = 1.5e-14 m
Energy = h c / lambda = 1.3e-11 J = 83 MeV
Search the web for something that emits 83 MeV photons!
