This panoramic image tracing constellations in the southern sky shows off a beautiful vista toward the center of our Milky Way Galaxy. It was recorded just last month near the city of Campos in northeastern Rio de Janeiro state, Brazil. A sugar cane field from one of the historic region's local farms lies in the foreground. From left to right, the view sweeps across the Galactic Center in Sagittarius, bright stars in the tail of Scorpius, the South Celestial Pole above and right of the gap in the sugar canes, the dark Coalsack Nebula, and the Southern Cross. The closest star system, Alpha Centauri, and the giant Omega Centauri globular star cluster also shine in the starry night.
