Southern Cross over Chilean Volcano.

Have you ever seen the Southern Cross? This famous four-star icon is best seen from Earth's Southern Hemisphere. The featured image was taken last month in Chile and captures the Southern Cross just to the left of erupting Villarrica , one of the most active volcanos in our Solar System . Connecting the reddest Southern Cross star Gacrux through the brightest star Acrux points near the most southern location in the sky: the South Celestial Pole (SCP), around which all southern stars appear to spin as the Earth turns . In modern times , no bright star resides near the SCP, unlike in the north where bright Polaris now appears near the NCP. Extending the Gacrux - Acrux line still further (from about four to about seven times their angular separation) leads near the Small Magellanic Cloud , a bright satellite galaxy of our Milky Way Galaxy . The Southern Cross asterism dominates the Crux constellation , a deeper array of stars that includes four Cepheid variable stars visible to the unaided eye. Just above the volcano in the image, and looking like a dark plume, is the Coalsack Nebula , while the large red star-forming Carina Nebula is visible on the upper left.
