Rio de la Plata
June 21, 2011
The photo above shows the Rio de la Plata taken with a fisheye lens in the evening twilight from near Buenos Aires, Argentina. The Rio de la Plata is the sediment-laden estuary of the Parana and Uruguay Rivers. Some geologists and hydrologists consider this body of water to be a marginal sea while others believe it's simply an extremely large river mouth -- perhaps the widest on Earth. The distance from one shore (Argentina) to the other (Uruguay) is more than 125 mi (200 km). Note Venus gleaming at top center and the city lights of Buenos Aires visible at far right.
