The First Picture of a Lake Outside Earth

See that shiny thing? That's a lake. But it's nowhere in Earth. It's in Titan, the largest moon of Saturn, 80% more massive than Earth's moon, and the only satellite with a dense atmosphere. According to Bob Pappalardo, from NASA:

This one image communicates so much about Titan - thick atmosphere, surface lakes and an otherworldliness. It's an unsettling combination of strangeness yet similarity to Earth.

The image of the lake was captured by the Cassini spacecraft on July 8. The probe was looking for this image since it arrived to Saturn in 2004. Previously, Cassini detected liquid methane lakes using infrared data, but this picture shows the 400,000-square-kilometer Kraken Mare lake in a way that has never seen before. So beautiful.
