Whether there is life on Titan, the largest moon of Saturn, is currently an open question and a topic of scientific assessment and research. Titan is far colder than Earth, but of all the places in the Solar System, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes, and seas on its surface.

2019年5月10日 · Gravity measurements made during fly-bys by NASA’s Cassini spacecraft revealed that Titan contains an ocean beneath its ice shell, and within this ocean, conditions are potentially suitable for life.

2019年7月15日 · Thanks to the data compiled by Cassini, scientists have now identified Titan as one of the most Earth-like worlds in our solar system. It’s the only place besides Earth to feature liquid rivers and lakes on its surface, and the only known moon with a substantial atmosphere.

2020年3月5日 · If there is life on Titan, it'd have to be pretty darn weird. Saturn's moon Titan has liquid lakes on its surface like Earth, so many have suggested it could have microbes swimming within.

2025年1月19日 · NASA researchers have confirmed the existence in Titan’s atmosphere of vinyl cyanide, which is an organic compound that could potentially provide the cellular membranes for microbial life to form in Titan’s vast methane oceans.

2024年11月3日 · Titan may have volcanic activity as well, but with liquid water “lava” instead of molten rock. Titan’s surface is sculpted by flowing methane and ethane, which carves river channels and fills great lakes with liquid natural gas. ... Although there is so far no evidence of life on Titan, its complex chemistry and unique environments are ...

2024年2月15日 · Titan's underground ocean, and similar oceans inside other icy moons in the outer solar system, may lack the organic chemistry necessary for life, according to new astrobiological...

2015年10月5日 · If there is life in Titan's seas, it is not life as we know it. It must be an alien form of life, with organic molecules dissolved in liquid methane instead of liquid...

2020年11月6日 · Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of scientists has identified a mysterious molecule in Titan’s atmosphere. It’s called cyclopropenylidene (C 3 H 2), a simple...

2020年1月10日 · NASA’s next destination in the solar system is the unique, richly organic world Titan. Advancing our search for the building blocks of life, the Dragonfly mission will fly multiple sorties to sample and examine sites around Saturn’s icy moon.
