NASA model of the Milky Way: gamma-ray study
NASA. LARGE FORMAT. The Milky Way galaxy modeled by NASA scientists. Not counting transient events such as gamma-ray bursts, the brightest object in the gamma-ray sky is the plane of our Milky Way galaxy. This glow results from a vast sea of cosmic-ray particles colliding with interstellar gas and dust, generating gamma rays. To study our galaxy, theorists create models of how these different particles interact with magnetic fields at different locations and with different strengths. Astronomers can then compare these models with actual observations made at radio, infrared, optical, ultraviolet and X-ray wavelengths to see how closely they match the data. 2017.
