Web1905 to 1917. – Einstein develops the concept of the light quanta (particles of electromagnetic radiation). 1910. – Bragg demonstrates that gamma rays ionize gas just like x-rays. 1911. – Rutherford discovers the atomic nucleus. 1912. – von Laue, Knipping & Friedrich demonstrate the wave nature of x-rays. 1912. Gamma-ray astronomy is the astronomical observation of gamma rays, the most energetic form of electromagnetic radiation, with photon energies above 100 keV. Radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy. In most known cases, gamma rays from solar flares … See more Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing them.
