Detection of CH3C3N in Titan's Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N2 and CH4 , with lesser amounts of hydrocarbons and nitrogen-bearing species.

Titan Has The Ingredients For Life

Catherine Neish is counting the days until her space launch. While the Western planetary geologist isn't space-suiting up for her own interstellar voyage, she is playing a key role in an international mission - dispatching a robotic drone to Saturn's moon Titan - set to blast-off in 2027.

Lakes on Saturn's moon Titan, composed of methane, ethane, and nitrogen rather than water, experience density driven stratification, forming layers similar to lakes on Earth.

We outline a flagship-class mission concept focused on studying Titan as a global system, with particular emphasis on the polar regions.

We present Cassini VIMS observations of sun glitter -- wave-induced reflections from a liquid surface offset from a specular point -- on Kraken Mare. Sun glitter reveals rough sea surfaces around Kraken Mare, namely the coasts and narrow straits.

Transit spectroscopy is a key tool for exoplanet atmospheric characterization. However, transit spectrum observations can be limited by aerosol extinction when gas opacities are weak.

Saturn's moon Titan is the only extraterrestrial body known to host stable lakes and a hydrological cycle. Titan's lakes predominantly contain liquid methane, ethane, and nitrogen, with methane evaporation driving its hydrological cycle.

Researchers from Chalmers University of Technology, Sweden, have made a new contribution to the ongoing search into the possibility of life on Titan, Saturn's largest moon.

We have studied the pressure and temperature dependence of solubility of nitrogen in methane and ethane using vapor-liquid equilibrium simulations of binary mixtures of nitrogen in methane and ethane for a range of pressures between 1.5 atm and 3.5 atm and temperatures between 90 K and 110 K, thermodynamic conditions that may exist on the Saturn's moon, Titan.

Dust Devils On Titan

Conditions on Saturn's moon Titan suggest dust devils, which are convective, dust-laden plumes, may be active.

Titan has an abundance of lakes and seas, as confirmed by Cassini. Major components of these liquid bodies include methane (CH4) and ethane (C2H6); however, evidence indicates that minor components such as ethylene (C2H4) may also exist in the lakes.

The complex organic chemistry harbored by the atmosphere of Titan has been investigated in depth by Cassini observations.

Thanks to the Cassini spacecraft onboard instruments, it has been known that Titan's ionospheric chemistry is complex and the molecular growth is initiated through the photolysis of the most abundant species directly in the upper atmosphere.

Scientists studying the weather and climate of Titan, Saturn's largest moon, have reported a significant seasonal variation in its energy budget - that is the amount of solar energy absorbed by the celestial body and the thermal energy it emits.

The first map showing the global geology of Saturn's largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains.

The Cassini/Composite InfraRed Spectrometer (CIRS) instrument has been observing the middle atmosphere of Titan over almost half a Saturnian year.

Titan is unique in the solar system as it hosts a dense atmosphere mainly made of N2 and CH4. Cassini-Huygens revealed the presence of an intense atmospheric photochemistry initiated by the photo-dissociation and ionization of N2 and CH4.

In situ exploration of the planetary atmospheres requires the development of laboratory experiments to understand the molecular growth pathways initiated by photochemistry in the upper layers of the atmospheres.

We have analyzed spectra recorded between 50 and 650 cm−1 by the Composite Infrared Spectrometer (CIRS) aboard the Cassini spacecraft at low and high emission angles to determine simultaneously the H2 mole fraction and ortho-to-para ratio in Titan's troposphere.

Some of the major discoveries of the recent Cassini-Huygens mission have put Titan and Enceladus firmly on the Solar System map. The mission has revolutionised our view of Solar System satellites, arguably matching their scientific importance with that of their planet.
