Data sent back by the Huygens space  probe from the Saturnian moon Titan show a frozen, orange world  shrouded in a methane-rich haze with dark ice rocks dotting a  riverbed-like surface the consistency of wet sand, scientists  said on Saturday.

NASA and university astronomers are eagerly awaiting  the launch of a&nbsp;space probe bound to collide with a comet and give  researchers a glimpse inside the solar system's&nbsp;icy  wanderers.&nbsp;

Astronomers using a giant telescope atop a volcano have discovered a hot spot at the tip of Saturn's south pole. The infrared images captured by the Keck I telescope at the W.M. Keck Observatory atop Mauna Kea on the Big Island suggest a warm polar vortex &#151; a large-scale weather pattern likened to a jet stream on Earth that occurs in the upper atmosphere. It's the first such hot vortex ever discovered in the solar system.

While earthquakes, steam and magma are getting all the attention on Mount St. Helens these days, the volcano's most unique feature could be the icy epitome of slow motion that has sprouted on its flanks in the last two decades: its glacier.

Mars, the red planet, may not after all be the dead planet. New research yesterday by European scientists suggests that volcanoes on Mars last erupted only 2 million years ago and could erupt again.

Cassini has photographed icy volcanic flows and a large lake of what could be methane on Saturn&#39;s mysterious moon Titan. The observations suggest Titan is geologically active and, and its environment
