Milky Way from Las Campanas, Chile
July 22, 2009
The photo composite above shows a striking view of the Milky Way, stretching from nearly one horizon to the other, as observed from the mid-latitudes of the Southern Hemisphere. It was captured in April 2009 from the Las Campinas Observatory in central Chile and is composed of more than 40 frames. South is at top and north at the bottom. From the northern and mid-latitudes of the Northern Hemisphere, the brilliant stars in Centaurus and the Southern Cross (Crux), at top, are too far south to be seen in the night sky. Note that the lava-like streams at the very top of the image are actually “time exposed” vehicle lights along a mountain roadway not far from the observatory.
Photo details: Canon Rebel XTi camera; 17 mm lens at 2.8; ISO 1600; guided exposures ranging from 3 minutes to 1 minute.
