Scientists: Liquid water erupting on Saturn moon
Thursday, March 9, 2006; Posted: 4:06 p.m. EST (21:06 GMT)
LOS ANGELES, California (AP) -- The Cassini spacecraft has found evidence of liquid water spewing from geysers on one of Saturn's icy moons, raising the tantalizing possibility that the celestial object harbors life.
The surprising discovery excited some scientists, who say the Saturn moon, Enceladus, should be added to the short list of places within the solar system most likely to have extraterrestrial life.
Recent high-resolution images snapped by the orbiting Cassini confirmed the eruption of icy jets and giant water vapor plumes from geysers resembling frozen Old Faithfuls at Enceladus' south pole.

"We have the smoking gun" that proves the existence of water, said Carolyn Porco, a Cassini imaging scientist from the Space Science Institute in Boulder, Colorado.
If Enceladus does harbor life, it probably consists of microbes or other primitive organisms capable of living in extreme conditions, scientists say.
The findings were published in Friday's issue of the journal Science.
David Morrison, a senior scientist at NASA's Astrobiology Institute, cautioned against rushing to judgment about whether the tiny moon could support life. Scientists generally agree habitats need several ingredients for life to emerge, including water, a stable heat source and the right chemical recipe.
"It's certainly interesting, but I don't see how much more you can say beyond that," Morrison said.
Scientists believe Mars and Jupiter's icy moons might have -- or once had -- conditions hospitable to life.
Saturn is around 800 million miles from Earth. Enceladus measures 314 miles (505 kilometers) across and is the shiniest object in the solar system.
It was long thought to be cold and still. But scientists now believe it is a geologically active moon that possesses an unusually warm south pole.
The water is believed to vent from fissures in the south pole. Porco said the venting has probably been going on for at least several thousand years, potentially providing a lasting heat source.
The Cassini-Huygens mission is a joint NASA-European Space Agency project. The spacecraft was launched in 1997 and went into orbit around Saturn in 2004, exploring its spectacular rings and many moons.
Cassini made three flybys of Enceladus last year and is expected to fly within 220 miles (354 kilometers) of the moon again in 2008.

ain't that cool

saturn has rings
so does uranus

very interesting... and exciting!... although you cant expect someone like the Murph to appreciate some of the finer points of scientific discoveries
Murphy2006-03-10 05:20:00
oh psh leave me alone i was having some immature fun.
Seriously though it's pretty cool i just felt like making a crude joke at science's expense.

Yay.. now to see how many biodomes we can fit within 300 miles! Hopefully that will solve our problem with over populated prisons!

Screw that why send criminals to space I wann go to space for fun!

I want to be the first person to play Lusternia from space.

Because every sci-fi movie wehre people go to another planet in a biosphere ends in DOOM!

Thats just lies, space is so cool they make stuff like that up to stop the riff raff from trying to go to it.
