Latest Huygens probe Stories
A 300-mile-wide patch that outshines everything else on Titan at long infrared wavelengths appears not to be a mountain, a cloud or a geologically active hot spot, University of Arizona scientists and Cassini team members say.
Images returned during Cassini's recent flyby of Titan show captivating evidence of what appears to be a large shoreline cutting across the smoggy moon's southern hemisphere. Hints that this area was once wet, or currently has liquid present, are evident.
Saturn's radio emissions could be mistaken for a Halloween sound track.
A team of European and US scientists, using Cassini-Huygens data, have found that Saturnâ€™s smoggy moon Titan may have volcanoes that release methane in the atmosphere.
A recent flyby of Saturn's hazy moon Titan by the Cassini spacecraft has revealed evidence of a possible volcano, which could be a source of methane in Titan's atmosphere. Images taken in infrared light show a circular feature roughly 30 kilometers (19 miles) in diameter that does not resemble any features seen on Saturn's other icy moons.
How old is Titan's surface? For years, Saturn's moon Titan was thought to have mastered the cosmetic surgery of the cosmos, with barely a mark or wrinkle to betray its true age. Close-up views provided by Cassini instruments show that Titan is nearly as flawless as it seems from a distance.
As the large amount of data collected by the European Space Agency's Huygens probe during its descent onto Titan is being processed, new views of this fascinating world become available.
Observations of Titan's atmosphere offer a unique look at how Saturn's giant moon compares to Earth. Titan is the only moon in the solar system with a substantial atmosphere. Like Earth, Titan's atmosphere is primarily composed of nitrogen, but unlike Earth, one of the most abundant constituents is methane (CH4).
During its closest flyby of Titan on April 16, NASA's Cassini spacecraft detected some surprisingly complex organic molecules floating in its upper atmosphere. Specifically, the spacecraft's mass spectrometer picked up the presence of a variety of hydrocarbons, including ethane and even octane.
Saturn's largest and hazy moon, Titan, has a surface shaped largely by Earth-like processes of tectonics, erosion, winds, and perhaps volcanism. Titan, long held to be a frozen analog of early Earth, has liquid methane on its cold surface, unlike the water found on our home planet.
Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...
Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
