2018-10-28 · These are difficult to study because of the high energies involved, they are sometimes very bright in "visible" light, and the fact that our atmosphere protects us from most gamma rays. To "see" these activities properly, astronomers send specialized instruments to space, so they can "see" the gamma rays from high above Earth's protective blanket of air.

This image identifies several blazars and one pulsar (PSR J1312+00) in a 20-degree-wide patch in the constellation Virgo. The view is centered at R.A. 13h 00m, Dec. -2d 00m. The LAT image is a five-year exposure of gamma rays with energies greater than 1 billion electron volts (GeV). Brighter colors indicate brighter gamma-ray sources.

This movie shows one cycle of pulsed gamma rays from the Vela pulsar as constructed from photons detected by Fermi's Large Area Telescope. The movie includes data from August 4 to Sept. 15, 2008. The bluer color in the latter part of the pulse indicates the presence of gamma rays with energies exceeding a billion electron volts.

12.8 days Gamma-ray energies of 152 Eu were measured with the uncertainties of 1.1–7.3 eV in the region of 290–720 keV using Ge spectrometers. To determine the 719 keV γ-ray energy of 152 Eu, we measured the 125 and 592 keV cascade γ-ray energies of 185 Os which provide the 717 keV cross-over γ-ray energy.

When these nuclei drop to the daughter energy level, a 500-keV gamma photon will be emitted. It is the combination of different energy levels and different transition routes that gives rise to the different energies in the typical gamma spectrum.
