Jupiter moon’s ocean is rich in oxygen
Cosmos ^ | 10/13/09

SYDNEY: The globe-spanning ocean on Jupiter’s moon Europa contains about twice the liquid water of all Earth’s oceans combined, says a new study, which finds it’s packed with oxygen which could support life.

Too bad being that near Jupiter is hazardous levels of radiation. or am I wrong on that?

The ping list or the list traveling to Jupiter's moon? :-)

Isn’t this about where the Uranus jokes start to appear?

Darn. We need to find a stargate or something.

For those who prefer the trendier vulgar pronunciation of Uranus, some real estate on the Venus colony awaits them (see C. M. Kornbluth’s “The Marching Morons”).

Luckily, water in liquid or solid form makes a great radiation shield. Submerged deep in Europa’s oceans you should be quite safe.

Sorta sounds like something straight out of Ender’s Game, except they were in an asteroid.

We may not even have to terraform Europa.

Getting there might be a bit of an exposure.

Oxygen suggests plant life, at least.

The surface is exposed to immense levels of radiation, but the ocean is deep under the surface. Practically zero radiation gets down there.

No, oxygen doesn’t necessarily mean life. Oxygen is created on icy worlds by solar energy splitting water into hydrogen and oxygen. It’s at a very low rate, though. And who’s to say that Europa wasn’t created with oxygen-rich seas?

I don’t think there’s any way to say whether life was created elsewhere in the universe, but we need to be realistic about the evidence.

...I concur with that fact...
...But, because the 7th planet has been brought up, for the jokers, Joke #1, Maybe there is more intelligent life there...
...Back to facts. Saturn has 30 plus moons. Read an article today that a small moon has geysers with ice and water vapor emitting from cracks on the surface. Joke#2, cracks,,, Naahh, fractures of the outer core. Liquid H2O beneath the ice holes. Joke#3, ice holes,,, Naahh, the surface...

Add me to the list also. Here is a good site for planet pics:

Some Of Our Oxygen Is Produced By Viruses Infecting Micro-organisms In The Oceans

ScienceDaily (Apr. 6, 2008) — Some of the oxygen we breathe today is being produced because of viruses infecting micro-organisms in the world’s oceans, scientists heard April 2, 2008 at the Society for General Microbiology’s 162nd meeting.

About half the world’s oxygen is being produced by tiny photosynthesising creatures called phytoplankton in the major oceans. These organisms are also responsible for removing carbon dioxide from our atmosphere and locking it away in their bodies, which sink to the bottom of the ocean when they die, removing it forever and limiting global warming.

“In major parts of the oceans, the micro-organisms responsible for providing oxygen and locking away carbon dioxide are actually single celled bacteria called cyanobacteria,” says Professor Nicholas Mann of the University of Warwick. “These organisms, which are so important for making our planet inhabitable, are attacked and infected by a range of different types of viruses.”

The researchers have identified the genetic codes of these viruses using molecular techniques and discovered that some of them are responsible for providing the genetic material that codes for key components of photosynthesis machinery.

“It is beginning to become to clear to us that at least a proportion of the oxygen we breathe is a by-product of the bacteria suffering from a virus infection,” says Professor Mann. “Instead of being viewed solely as evolutionary bad guys, causing diseases, viruses appear to be of central importance in the planetary process. In fact they may be essential to our survival.”

Viruses may also help to spread useful genes for photosynthesis from one strain of bacteria to another.

That’s about as big as science news gets.
