Venus by the Sea

Venus sparkles like a diamond over the Rio de la Plata near Buenos Aires, Argentina. The Rio de la Plata is an estuary of the Parana and Uruguay Rivers.Its so large (125 miles, or 200 kilometers from shore to shore) that some geologists consider the Rio de la Plata to be not a river mouth, but a marginal sea. The lights of Buenos Aires are visible in the far right of this May 28, 2011 photo.
