Latest Lakes of Titan Stories
Cassini/Huygens scientists have discovered exactly where on Saturn's largest moon, Titan, the European Space Agency's (ESA) Huygens probe landed last January. Knowing the landing location will allow them to directly compare data from Huygens with remote sensing data from NASA's Cassini orbiter.
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.
Scientists peering through a ground-based telescope say the surface of Saturn's planet-sized moon Titan appears dry and not awash in oceans of liquid hydrocarbons as is commonly believed.
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.
Titan's atmospheric winds, temperature and mixing have been revealed by new observations from the Cassini spacecraft. The thick atmosphere of Saturn's giant moon is rich in organic compounds, whose chemistry may be similar to that which occurred on Earth before the emergence of life.
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).
Arizona's Jonathan Lunine presented a lecture entitled "Titan: A Personal View after Cassini's first six months in Saturn orbit" at a NASA Director's Seminar on January 24, 2005. Lunine discusses the question of missing methane in an edited transcript of Part 2.
Cassini-Huygens supplied new evidence about why Titan has an atmosphere, making it unique among all solar system moons. Scientists can infer from Cassini-Huygens results that Titan has ammonia, said Jonathan I. Lunine, an interdisciplinary scientist for the European Space Agency\'s Huygens probe that landed on Titan last month.
University of Hawaii astronomer Toby Owens spoke with Astrobiology Magazine shortly after the successful Huygens mission had completed. In this part of the interview, Owens talks about the significance of methane in Titan's atmosphere.
One week after the successful completion of Huygensâ€™ mission to the atmosphere and surface of Titan, the largest and most mysterious moon of Saturn, the European Space Agency is bringing together some of the probeâ€™s scientists to present and discuss the first results obtained from the data collected by the instruments.
