New Ocean Life Discovered at the 'Hadal Zone' (Deeper than Mount Everest is High)

A black smoker In the "hadal" zone, which at 11,000 meters is deeper than Mount Everest is high – the pressure rises to 1,000 bar, or a ton per square centimeter. And as there is practically no light, and plants cannot grow, there is little food. It offers a glimpse of what life on Jupiter's moon, Europa, might look like. A new species of archaebacteria, Pyrococcus CH1,was recently discovered thriving on a mid-Atlantic ridge within a temperature range of 80 to 105°C and able to divide itself up to a hydrostatic pressure of 120 Mpa (1000 times higher than the atmospheric pressure). Excedrin Migraine won't help down there.

This discovery was made by an international team of microbiologists of the Microbiology of Extreme Environments Laboratory in partnership with the Institute of Oceanography of Xiamen (China) and the Earth Science Laboratory. This archaebacteria had been isolated from samples by a Franco-Russian team that explored the mid-Atlantic ridge for six weeks searching for new hydrothermal vents.

The piezophilic microorganisms constitute a subgroup of extremophiles. Discovered on the site “Ashadze”(2) at 4100 meters depth, the deepest vent field explored so far, the CH1 strain was successfully isolated and assigned to the genus Pyrococcus, within the Euryarchaeota lineage of the Archae domain. The discovery extends the known physical and chemical limits of life on Earth.

The reason scientists believed for so long that life did not exist in the deepest parts of the sea is because the oxygen that filters down is centuries old, having formed near the surface through photosynthesis by microscopic plants known as phytoplankton.

Pyrococcus CH1 is only one on many examples of extremophilic microorganisms on our planet, all of which point vividly to what we might eventually discover as NASA's future probes explore the moons of Saturn and Jupiter.

Extremophiles are the ultimate adventurers. These organisms thrive where other microbes don’t dare venture: boiling water holes, freezing lakes, and toxic waste dumps. Researchers have sequenced the genomes of two extremophiles that live at the bottom of Ace Lake in Antarctica, where there is no oxygen and the average temperature is a brutal 33 degrees below Fahrenheit.

Extraterrestrial life is the most interesting thing ever, bar nothing.  We have two possible life-locations right here on our solar system doorstep - but we have to choose which to check.  We want to go everywhere, but with a price-tag of billions of dollars per outer-planet probe we have to decide and flipping a coin just won't cut it.

Option Number One is Jupiter's Europa, the favored satellite son of many exobiologists and even Arthur C. Clarke himself.  While distinctly non-Terran, huge sub-surface lakes probably heated by tidal stresses, and even an extremely tenuous oxygen atmosphere make it a leading contender.  Hot water and even some air?  Is there a more likely life-site without tiny bacteria-sized jacuzzis?

Number Two is Saturn's Titan, a very-Terran option whose surface lakes, shorelines, seasons and relatively thick nitrogen atmosphere mean it's viewed as an early-model Earth.  And 100% of all know Earths have awesome life on them!  The significantly lower temperature is a bit of a stumbling block (it's ten times as far from the sun as us), but the possibility of subterranean microbial life - or even a prebiotic "Life could happen!" environment - would be a massive result.

Wow, truly amazing stuff dude. Seriously.

This is horribly written.

"And 100% of all know Earths have awesome life on them!"

wtf?

OK, I'll bite; why is Enceladus not mentioned in this article? The best I have heard is a paraphrase from a Nat Geo special..."Enceladus has everything! Liquid water spewing from it's south pole with a sign saying, FREE SAMPLES, COME AND GET THEM!" Don't need to drill through 10/30/60/? MILES of ice as on Europa. Just set a couple of Mars rovers type robots near the vents, fly a sniffer/sampler type robot around the plumes that are spewing water for thousands of miles into space and see what's up. The interest is the layer where the subsurface water, heated by interior forces, meet the top layer ice and all that friction! Cheaper, easier, faster. What's the problem?

Regarding the photo.....Didn't BP cap those? (just kiddin')

nice to see Luke's byline on a story, even if it lacks his usual humor...I was starting to wonder if you'd fired your resident smart-ass...but i thought you guys hired a proofreader? I mean, " brutal 33 degrees below Fahrenheit"? C'mon!

Was on of the most very important discovery Medical Solution for many Contacious Disease such as HIV, CANCER etc, THIS Revelation i had made it in a Dream when i was in Malaysia on August 2008.

My dream talk about the solution for long life, will be discover in Mount Hadal.

Alert the World Scientific that the hold a solution for many year problem.


Rev John


i've send you this for my homework but if it ok i kan do it only.

beautifully written...so much information!!
