377-seti-galaxy-dixon –The Milky Way Galaxy - A grand, sweeping spiral galaxy tilts dynamically across a black cosmic void, its brilliant yellow-white core surrounded by tightly wound spiral arms. The structure is heavily detailed with mottled blue star-forming regions, pink emission nebulae, and complex lanes of dark interstellar dust cutting through the galactic plane. In the deep background to the upper left, the Andromeda galaxy accompanied by a tiny satellite galaxy drifts in isolation. digital painting by Don Dixon for Scientific American
