Hot Topic Solar System Saturn Titan
 
Unlocking Titan's Methane
Topic: Titan
03/05/06
Summary: The presence of methane in Titan's atmosphere is one of the major enigmas the Cassini-Huygens mission is trying to solve. A new model for the source of the methane appears in the March 2 issue of Nature.

Forecasting Titan
Topic: Titan
01/28/06
Summary: Using recent Cassini, Huygens and Earth-based observations, scientists have been able to create a computer model which explains the formation of several types of ethane and methane clouds on Titan.

Purple Haze
Topic: Titan
01/03/06
Summary: With its thick, distended atmosphere, Titan's orange globe shines softly, encircled by a thin halo of purple light-scattering haze.

The Methane Mystery
Topic: Titan
12/10/05
Summary: The methane giving an orange hue to Saturn's giant moon Titan likely comes from geologic processes in its interior according to data from the Huygens Probe. Huygens, which descended through the moon's thick atmosphere on Jan. 14, 2005, also found evidence of liquid methane in the surface material.

Titan: Passport to the Early Earth?
Topic: Titan
12/01/05
Summary: If there is life on Saturn´s moon Titan, it's not producing all that methane in the atmosphere. That is one conclusion in a series of Cassini/Huygens mission reports published online this week by the journal Nature.

Titanic Smog
Topic: Titan
11/18/05
Summary: Looking back toward the sun brings out the thin haze that hovers 500 kilometers (310 miles) above Saturn's moon Titan.

Titan's Rocks of Ice
Topic: Titan
11/07/05
Summary: Saturn's giant moon Titan is so cold that, on its surface, water is as hard as a rock - literally. Chris McKay, a planetary scientist at NASA Ames Research Center, recently gave a public lecture, sponsored by the Planetary Society, about what scientists have learned about Titan from the European Space Agency's Huygens probe.

Radaring Titan
Topic: Titan
11/05/05
Summary: The Cassini spacecraft carried the European Space Agency's Huygens probe to Saturn and released it in December 2004. The probe landed on Titan Jan. 14, 2005, acquiring a set of images using the descent imager/spectral radiometer camera as it parachuted to the surface. As Cassini continued to orbit Saturn, its imaging science subsystem and visual and infrared mapping spectrometer mapped the region where the Huygens probe landed. On Friday, Oct. 28, 2005, Cassini's radar instrument provided the highest resolution orbital data yet of this area.

Titan: Greenhouse and Anti-greenhouse
Topic: Titan
11/03/05
Summary: Earth, Mars and Venus all have greenhouse effects. So does Saturn's giant moon Titan. But Titan also has an anti-greenhouse effect. Chris McKay recently gave a public lecture, sponsored by the Planetary Society, in which he talked about the scientific results of the Cassini-Huygens mission to Saturn and Titan.

Titan Weather: Cloudy Every 15 Years
Topic: Titan
10/31/05
Summary: There is only one moon in our solar system that has clouds, Saturn's giant moon Titan. Chris McKay, a planetary scientist at NASA Ames Research Center, recently gave a public lecture, sponsored by the Planetary Society, about what scientists have learned about Titan from the Cassini-Huygens mission.
