Shown above is the night sky above the Cesco Observatory in El Leoncito National Park, near San Juan, Argentina. Featured at top center are the Large and Small Magellanic Clouds. These satellite galaxies of our own Milky Way lie approximately 160,000 and 200,000 light-years away, respectively, and are easily visible from the Southern Hemisphere. Several dozen satellite or dwarf galaxies orbit the Milky Way, but only the Magellanic Clouds are naked-eye objects. The glow of the Milky Way is at left.

In the foreground is the Mobile Astronomical System of Telescope- Robots (MASTER), installed as the product of the working agreement between CESCO, the National University of San Juan and Moscow State University. Photo taken on December 1, 2016.
