Confirmed: Titan has a Subsurface Ocean!

  Nothing like it has been seen before beyond our own planet: large tides have been found on Saturn’s moon Titan that point to a liquid ocean – most likely water – swirling around below the surface. A possible scenario for the internal structure of Titan, which includes a global subsurface ocean beneath an icy [continue reading]

  NASA’s Cassini spacecraft has spied long-standing methane lakes, or puddles, in the “tropics” of Saturn’s moon Titan. One of the tropical lakes appears to be about half the size of Utah’s Great Salt Lake, with a depth of at least 3 feet (1 meter). Saturn’s rings lie in the distance as the Cassini spacecraft [continue reading]

Cassini Finds Titan Lake is like a Namibia Mudflat

A new study analyzing data from NASA’s Cassini spacecraft suggests that the lake, known as Ontario Lacus, behaves most similarly to what we call a salt pan on Earth. A group led by Thomas Cornet of the Université de Nantes, France, a Cassini associate, found evidence for long-standing channels etched into the lake bed within [continue reading]

Despite many years of space exploration, we have no evidence of the sound of other planets. While most planetary probes have focused on imaging with cameras and radar and a couple have carried [continue reading]

Happy Birthday Titan!

Saturn’s Earthlike Moon – Target of Proposed ‘TiME’ Mission – Discovered in 1655 On March 25, 1655, Dutch astronomer Christiaan Huygens, using a telescope he built himself, observed a small bright dot suspiciously close to the planet Saturn. Huygens correctly surmised that it might be a moon of that planet, and confirmed as much by [continue reading]
