Medicine & TechnologySaturn is the second largest planet in our solar system and has developed quite a reputation because of its impressive ring system, but it also has 62 moons. The largest moon, Titan, is the only one that actually has its very own atmosphere. NASA now has plans to take a closer look at what is going on down on Titan, but not by using a spacecraft. Instead it will use a submarine.
If life can exist in these types of conditions here on Earth, the possibility that it also exists elsewhere in our solar system increases dramatically. For instance, what could lie beneath the ice of Jupiter's moon Europa or perhaps Saturn's moon Enceladus?
In a new study published this week by researchers from Cornell University, the team of researchers has modeled a new methane-based life form that can metabolize and reproduce, similar to the oxygen-based life forms here on Earth. And more than that, the researchers say that these life forms could flourish in the harsh, cold environment of Saturn's moon, Titan. Titan's surface is filled with seas of liquid methane that researchers believe could harbor these methane-based cells.
Beneath the glaring surface and choppy waves, many secrets are hidden here in the oceans of Earth. The vast depths hide species unknown to men, lost treasures at the seafloor and perhaps even a cryptid or two. And while terrestrial studies of planets may have been interesting in the 20th century, space agencies are looking to aquatic surveys which may one day reveal the origins of life even farther out in space.
While researchers have long known of Saturn’s largest moon, Titan, and its sandy surface, new research presented this week in two separate studies published in the journal Nature reveals that the 300 foot sand dunes on the moon’s surface may have originated from very different circumstances than those on Earth. Titan, which is much like the Earth, is one of the most intriguing moons our solar system has come to offer. But while it is the only other celestial body that has standing reservoirs of liquid on its surface and fields of dunes like those of the Sahara desert, astronomers are now finding that the events leading to Titan’s surface are far unlike what happened here on Earth.
