385-galactic-atmosphere-dixon – Even the galaxy has a kind of weather, in which fountains of tenuous gas arch high above the galactic plain through vents blasted by supernova explosions. A scientific visualization depicts the high-energy, turbulent gas dynamics within a galactic atmosphere or circumgalactic medium. An intense, linear orange-red horizon of hot plasma bisects the composition, venting loops and tendrils of cool purple and magenta gas into the surrounding void. On the right, a brilliant white energetic flare ionizes a broad swath of the interstellar medium, creating a dense, glowing purple cloud structure. digital painting for Scientific American, © Don Dixon
