We don't even know if life originating in water would end up looking like earthly life. Enceladus seems to have all the things that people have known about, or thought to look for, in asking the question, did life get started elsewhere in our solar system? And, in fact, some of the very, very early observations in which the geysers—or the jets, as I call them—were first seen had been given a title with the word

And the fact that we see salt in the solid particles tells us that the subterranean liquid is in contact with rock.

Our editors will review what you’ve submitted and determine whether to revise the article.For thousands of years humans have wondered whether they were alone in the There are about 200 billion stars in the Milky Way Galaxy. Additional funding is provided by the NOVA Science Trust.CalTech Alumni Association/Cassini Imaging Team, SSI, JPL, ESA, NASNOVA: When were the plumes on Enceladus dicovered, and before the flybys began did you expect to find anything like that?

Even if the ocean or the sea on Enceladus lasts only a few hundred million years, if life only took 10 million years to get started, it could have gotten started there. The basic building blocks of life are present. When and where do those things happen? Venus is 7,521 miles wide (12,104 km). So the only other plausible mechanism left is tidal flexure. We now strongly suspect that the jets are coming from liquid water. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.At the center, gravity pulled more and more material in. If any compound were much more massive, the Cassini instrument would not be able to detect it. People will say, well, we might have life on the surface of Titan.

But Carolyn Porco, the leader of the Cassini Mission Science team to Saturn, believes that the moon Enceladus is the best candidate for finding simple organisms in the solar system in our lifetime.Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. Are we seeing a monotonic decrease in heat output, with Enceladus getting colder and colder with time so that eventually all the liquid freezes and it becomes entirely solid and it never can get warm enough again to become liquid?

It's pretty widespread throughout the solar system, and it's probably pretty widespread throughout the cosmos. 3 / 10. Should life be discovered elsewhere in the Solar System, astrobiologists suggest that it will more likely be in the form of extremophile microorganisms. On Mars they're talking about possibly finding fossilized life. Other moons and planets in the solar system—Mars, Titan… So the answer to your question is, yes, this really has broadened our view of what kinds of environments we might find biotic chemistry in.

And, of course, the general state of the country's finances also puts us and everybody else in a tremendous state of uncertainty. One astronomical unit (or AU) is the distance from the Sun to Earth, or about 93 million miles (150 million kilometers). [< a href=http://www.space.com/15257-titan-saturn-largest-moon-facts-discovery-sdcmp.html>Titan is Saturn's largest moon and the only world in the solar system (besides Earth) known to sport liquid lakes. It's the difference between the way your left hand and your right hand are configured.

In ancient times and throughout the Middle Ages, the common view was that Earth was the only “world” in the universe. Director, NASA Planetary Science Division:

Some moons of Jupiter and Saturn are intriguing, and there's also the chance for some surprises somewhere on Mars.Here are my top six candidates for the best spots to search for primitive alien life in our solar system.In 2005, NASA's Cassini spacecraft photographed geysers of frozen water spewing from cracks in Enceladus' southern hemisphere. They don't even require anything that's been made by sunlight.
