Scientists have confirmed that Saturn’s moon, Titan, does indeed have a giant lake containing liquid. According to Space.com:
“This is the first observation that really pins down that Titan has a surface lake filled with liquid,” said lead researcher Robert Brown of the University of Arizona‘s Lunar and Planetary Laboratory in Tucson.
Called Ontario Lacus [because it is larger than North America's Lake Ontario], the lake extends 150 miles (235 kilometers) and covers an area of about 7,800 square miles (20,000 square kilometers). The lake structure is filled mostly with methane and ethane, hydrocarbons that are gases on Earth but liquid on the bone-chilling surface of Titan.
What does this mean? Well, what it means is that Titan could eventually show signs of life. It is also the only moon we’ve discovered to support a planet-like atmosphere. The deeper we explore the universe, the more exciting and frightening it is. Here’s one of my favorite film interpretations of the depths of space. It’s the opening sequence to the film CONTACT and one of the loneliest, most frightening, most exhilarating arguments in favor of life beyond Earth.
