With a thick atmosphere, clouds, a rain cycle and giant lakes, Saturn's large moon Titan is a surprisingly Earthlike place. But unlike on Earth, Titan's surface is far too cold for liquid water - instead, Titan's clouds, rain, and lakes consist of liquid hydrocarbons like methane and ethane (which exist as gases here on Earth). When these hydrocarbons evaporate and encounter ultraviolet radiation in Titan's upper atmosphere, some of the molecules are broken apart and reassembled into longer hydrocarbons like ethylene and propane.
NASA's Voyager 1 spacecraft first revealed the presence of several species of atmospheric hydrocarbons when it flew by Titan in 1980, but one molecule was curiously missing - propylene, the main ingredient in plastic number 5. Now, thanks to NASA's Cassini spacecraft, scientists have detected propylene on Titan for the first time, solving a long-standing mystery about the solar system's most Earthlike moon.
NASA Planetary Scientist Conor Nixon explains his discovery of propylene on Titan, Saturn's largest moon. Scientists have known about the presence of atmospheric hydrocarbons on Titan since Voyager 1 flew by in 1980, but one molecule, propylene, was curiously missing. Now, thanks to new data from NASA's Cassini spacecraft, propylene has been detected for the first time on Titan.

Ocean Worlds: The Search for Life
Read moreNASA scientists discuss the search for life on the ocean worlds of our solar system and beyond.Watch this video on the NASA Goddard YouTube channel.Universal Production Music: “Superluminal” by Lee Groves and Peter George Marett; “Earthrise,” “Prism Lights,” and “Uncertain Ahead” by Ben Niblett and Jon Cotton; “Infinite Sky” and “Human Architecture” by Andy Blythe and Marten Joustra; “Imagine If” by Paul Werner || Life as we know it requires three ingredients: energy, organic molecules, and liquid water. Our search for life beyond Earth is a search for planets, dwarf planets, and moons that harbor substantial liquid water. We call these places “ocean worlds.” We’re learning that ocean worlds could be ubiquitous in the galaxy. Just in our solar system, we have found evidence of oceans on Saturn’s moons Titan and Enceladus; Jupiter’s moons Europa, Ganymede, and Callisto; Neptune’s moon Triton; and on Pluto. We also believe that Venus and Mars may have had oceans billions of years ago. Could they have supported life? NASA’s research on oceans also includes our own planet and helps us to better understand the role of Earth’s ocean in our planet’s climate system. As we learn more about our own oceans, we will better understand worlds beyond Earth. Discover more about ocean worlds. ||

Cassini's Infrared Saturn
Read moreSince arriving at Saturn in 2004, Cassini has used its Composite Infrared Spectrometer (CIRS) to study the ringed planet and its moons in heat radiation. Complete transcript available.Watch this video on the NASA Goddard YouTube channel.Music provided by Killer Tracks: "Particle Waves," "Odyssey," "Solaris," "Expansive,""Horizon Ahead," "Ion Bridge," "Outer Space" || The Cassini-Huygens mission arrived at Saturn in 2004, beginning an epic thirteen-year tour of the ringed planet and its many moons. Cassini and its companion probe, Huygens, were an international collaboration between NASA and the European Space Agency (ESA). Cassini carried an impressive array of scientific instruments, including the Composite Infrared Spectrometer (CIRS) built at Goddard Space Flight Center. By studying the Saturn system in heat radiation, CIRS observed hot spots in a giant Saturn storm, discovered a new hydrocarbon in Titan's smoggy atmosphere, found unexpected surface heating on Mimas and Tethys, and even detected evidence of a liquid water ocean under the icy shell of Enceladus. This video explores Cassini CIRS' greatest hits, as told by instrument team members Michael Flasar, Conor Nixon, and Carrie Anderson. Learn more about the CIRS instrument and team. ||

Crude Matter
Read moreWhat do car bumpers and computer speakers have in common? Both can be created from raw materials found on Earth or on Titan, Saturn’s largest moon. Titan is the only moon in the solar system with a significant atmosphere. In some ways its atmosphere is similar to Earth’s, but rather than being rich in oxygen, it’s rich in hydrocarbons—chemical compounds made of the elements carbon and hydrogen. In 1980, NASA's Voyager 1 spacecraft flew by Titan and detected different types of hydrocarbons in its atmosphere, including methane, ethane and propane. Now, NASA’s Cassini spacecraft has added one more to the list: propylene, a chemical building block used in the manufacture of plastic consumer goods. Watch the video to learn more. ||
